CMMS – Cloud-based versus on-site installs Most CMMS applications fall under two categories: on-site and cloud-based. BY PETER PHILLIPS Computerized maintenance management systems (CMMS) are a hot topic for many corporations and maintenance departments. Maintenance departments may be looking to purchase their first CMMS or upgrading their current maintenance software. Maintenance departments use different tools and resources to maintain equipment, one of the crucial ones is CMMS. Both on-site and cloud-based CMMS solutions are designed to provide an application that can plan and track equipment maintenance. 10 MRO / Winter 2023
Typically, when people think of software, the concept is, there’s an application, you install it on a computer, phone, or tablet, and use it. When a user installs software, it’s typically tied to the device. In the case of a traditional CMMS, it’s deployed onsite and is tied to the on-site hardware and is deployed on each computer across the organization. Cloud-based solutions are entirely the opposite. The application is not tied to the company’s hardware and resources. With cloud-based systems users can access the application on any device that has an Internet
connection. With cloud-based systems, fewer IT resources are required as the cloud-based solutions don’t need maintenance – everything is done by the vendor through a support contract. Finally, cloud-based solutions are typically cheaper to implement and operate.
Benefits of a cloud-based CMMS Unrestricted access
Users are not tied to the premise or the workshop, they can access the app from anywhere and whenever the work requires them to. In contrast, older CMMS requires them to be present on the site.
Device access
Apps can be accessed from smartphones and tabloids, users only need to log-in and have an Internet connection. The maintenance planner, supervisor and technicians can use their mobile devices or workstations to keep track of the maintenance MROMAGAZINE.COM

SOFTWARE
tasks, assign new work orders, and provide feedback when necessary – something that’s not always possible with on-site solutions.
Reduced burden on IT resources
The solution is handled by the vendor. The IT team can show a user or provide a manual on how to access and use the CMMS cloud-based app on their devices. Maintenance team members can start using the app right away after logging in. With on-site solutions, there can be issues, for example, maintenance, implementation, and operating system updates. All of these require servers, hardware, and more IT personnel, incurring costs in the process.
Seamless updates
Major updates can be long, cumbersome, and disruptive. Cloud-based CMMS software, makes updates seamless, users are notified about updates and no other actions are required by IT or users. With on-site solutions, even the smallest updates can be time-consuming, whereas, with cloud-based solutions, the under-the-hood improvements are occurring constantly.
Faster implementation
Organizations need to ensure that required resources like the hardware and servers are available, and CMMS supporting resources and software loaded on the servers. While it might sound simple, getting management to sign off on machinery and software can be time-consuming. Organizations just need to make the recurring application payment to the vendor, and they will provide accounts to use the solution. Users log onto their devices on a secure Internet connection to use it, making implementation faster. With appropriate training and demonstration, maintenance team members can start using it right away.
Reduced costs upfront
Photo: PaulShlykov / Adobe Stock
A dedicated IT person is not required. There are no additional servers or hardware required, the application is easy to implement, and can be used from any compatible device. As a result, organizations that use cloud-based solutions are saving up-front costs. The payment model is quite simple – organizations need to pay a certain amount based on the number of users.
Better support and security
Security and maintenance is taken care of by the vendor. This relieves the IT personnel from having to troubleshoot problems with on-site CMMS solutions. When a user identifies a problem with the cloud-based solution, they only need to report it to vendor support. @MROmagazine
Scalable
A unique benefit for dynamic organizations is scalability. For instance, if an organization has few maintenance team members now, it needs a solution that can match the lower workload. However, if the same organization aims to expand its maintenance team significantly, it needs a solution that must be able to match the increased workload and maintenance tasks.
Enhanced productivity
The maintenance team is completely mobile with work orders on their tablets and access to parts inventory and equipment information through the app. The users just need to log-in to the authorized devices and they’re good to go, they get access to crucial information, such as spare parts availability, assets, vendors, and tasks. These modern maintenance management apps cut down response time to unexpected equipment breakdowns and prevent production disruptions.
Improved collaboration
Cloud-based CMMS applications ensure that asset, vendor, spare parts, and technician information are kept in a centralized location in an organized manner. Moreover, authorized users can monitor the progress of technicians, work orders, and repairs. While the maintenance supervisor can add further work details and schedule work, technicians can update the status of their assigned work orders using the app. Regular workers including production supervisors and operators can also submit work requests. Robust maintenance management apps also allow them to add images
or videos to show the precise problems with the faulty equipment. Maintenance supervisors, upon verification of the work request, can assign technicians to work order for action or can add it to the maintenance backlog. All in all, a cloud-based CMMS helps improve collaboration between the production department and streamline maintenance efforts. CMMS vendors list potential benefits of their software, they include: • Reduce equipment downtime; • Increase productivity; • Lower maintenance costs; • Improve inventory management; • Schedule preventive maintenance; • Increase life of equipment; • Enhance work order management; • Generate custom reports; • Make data driven maintenance decisions; and, • Meet compliance and safety standards. The trick to choosing a CMMS for your company, is finding a system that fits the maintenance department’s needs and ease of use and provides reports and KPIs to guide the maintenance team to effectively maintain the equipment and spare part inventory, and to fit the maintenance department budget.

Creating an effective hearing conservation program Excessive noise in the workplace is a significant health concern, affecting millions of workers across Canada. BY THE CANADIAN CENTRE FOR OCCUPATIONAL HEALTH AND SAFETY (CCOHS)

Hearing conservation programs can help address noise hazards by emphasizing the early detection and control of excessive noise levels through appropriate measures to protect workers’ hearing.
outlines an occupational exposure limit of 85 dBA of continuous noise over an eight-hour period, except for federal workplaces, which have a limit of 87 dBA. When noise exceeds the jurisdiction’s exposure limit, controls must be implemented. Alberta, British Noise exposure limits in Canada Columbia, Manitoba, Newfoundland Across Canada, each jurisdiction and Labrador, Northwest Territories, Nunavut, Prince Edward Island, Saskatchewan, and workplaces under the federal jurisdiction require a hearing conservation program when noise exceeds the exposure limit. While not all jurisdictions have a requirement for a hearing conservation program, the elements of a program, such as training, noise assessments, and audiometric testing, also known as hearing testing, are necessary when workers are exposed to noise above the exposure limit. The CSA Standard Z107.56, Measurement of noise exposure, recommends that the employer conduct a noise assessment if noise levels in the workplace exceed 80 dBA. This recommendation extends to any changes MROMAGAZINE.COM

It’s estimated that over 11 million Canadians aged 19 to 79 have worked in noisy environments, defined as the need to speak in a raised voice to communicate with co-workers at arm’s length. Of those workers, 56 per cent were classified as vulnerable to noise—they were not required to use hearing protection and only did so sometimes, rarely, or never. Constant exposure to excessive noise is a hazard that, in the shortterm, can be disruptive and affect our ability to hear signals, speech, and machinery. In the long-term, it can lead to noise-induced hearing loss, permanently damaging workers’ hearing and affecting their quality of life. Hearing loss can also occur from a single traumatic event, such as a sudden burst of extremely loud noise near the ear. In less extreme cases, excessive noise exposure can still cause damage. Workers can experience non-auditory effects such as increased stress, disruptions to cardiovascular function (changes to blood pressure and/or heart rate), sleep problems, and impacts to their mental health.
in the workplace such as renovation or repair work, when new equipment is introduced, or a modification is made to a work process that may result in a significant change in a worker’s exposure to noise.
Key elements of a program
The first step in any hearing conservation program is to assess workplace noise levels. This step involves conducting noise monitoring to determine the magnitude of exposure in different areas and job roles. Using sound level meters and noise dosimeters help to ensure accurate measurements. One of the primary objectives of workplace hearing conservation programs is to control noise at the source. Substituting equipment with quieter alternatives or implementing engineering measures, such as sound insulation, can help reduce noise levels and minimize employee exposure. Policies and procedures that limit workers’ exposure to excessive noise can also be introduced. This may include limiting the duration of tasks in noisy environments, implementing a job rotation schedule to reduce cumulative noise exposure, and designating rest breaks in quieter areas. When noise levels cannot be adequately reduced, employers must provide suitable hearing protection, such as earplugs or earmuffs. Workers must be trained in the proper use, fit, maintenance, and care of personal protective equipment (PPE) to ensure their effectiveness in reducing noise. Regular audiometric testing is a critical component of these programs. It involves baseline and periodic assessments of employees’ hearing abilities to detect any changes over time. By tracking changes in hearing thresholds, employers can monitor the effectiveness of controls, identify early signs of hearing loss, and take appropriate actions.
health issues like increased stress levels and tinnitus, which causes a ringing or buzzing in the ear. Through these programs, employers demonstrate their commitment to the health and safety of their workforce while fostering a sense of well-being and job satisfaction among employees.
By integrating noise monitoring, effective controls, and audiometric testing into an effective hearing conservation program, employers can protect employees by reducing the risk of noise-induced hearing loss, creating a safer and healthier work environment for everyone.
The Canadian Centre for Occupational Health and Safety (CCOHS) promotes the total well-being — physical, psychosocial, and mental health — of workers in Canada by providing information, advice, education, and management systems and solutions that support the prevention of injury and illness. Visit www.ccohs.ca for more safety tips.
Provide education and training
Make sure to provide education and training on the measures that are in place to reduce exposure and the elements of the hearing conservation program. Workers must be aware of the risks associated with elevated noise exposure and the long-term effects of noise-induced hearing loss. Training should also include the safe use and limitations of hearing protection, covering all elements listed in CSA Z94.2, Hearing protection devices – Performance, selection, care, and use. Education and training should be provided at regular intervals, at least once every two years, or when conditions change.

techniques to monitor the operating condition of equipment. These range from sensory techniques to the application of highly sophisticated technologies such as fast Fourier transform (FFT) analyser, to determine the causes of vibration frequencies in rotating equipment. The use of testing techniques can only be justified if they demonstrate a clear economic benefit. Substantial evidence exists that the intelligent use of even simple testing techniques will provide huge benefits to industry including: 1. Elimination or reduction of catastrophic machine failures and secondary damage where a failure has occurred. 2. Reduction in maintenance costs by avoiding repairs. 3.

Easy to use testing techniques by operators are useful for troubleshooting equipment
At least annually, a thermographic analysis should be carried out to locate hot spots in electric motors and mechanical devices such as drive couplings, bearings, and gear drives. applied by operators must be gathered when equipment is at operating temperature and taken at the same point on the machine component when the data is collected. The following testing techniques are common, easily applied, and only require that operations personnel have a sound knowledge of their equipment’s operation.
Q | Do the applicable equipment operators understand how contaminants enter a lubricated system?
LOGIC: Contamination of machine systems occurs in four ways, generated by the system itself (by normal wear, poor system or component design, surface fatigue and temperature related chemical reactions), implanted (by welding slag), induced (by careless maintenance practises), and escaped contamination (that enters a lubricated system through poor quality filters or poor filtration system design). An operator’s simple contamination test is to obtain an oil sample in a glass jar allowed to sit overnight. When the jar is turned over, any contaminant will remain visible on the bottom surface of the jar. A decision can be made for further laboratory testing.
Q | Do the equipment operators know
how to determine if water is a problem in a machine system?
LOGIC: Water contamination in a lubricated component can be determined by placing a few drops of oil on a hot plate. If the oil drops crackle or sizzle, there is excessive water present.
Q | Do operators know how to
determine how effective oil filters are?
LOGIC: Every time an oil filter is replaced, it should be cut open, the filter media spread on a bench; and using a good quality magnifying glass or microscope, contaminants and wear metals will be obvious. A magnet passed under the filter media will move all ferrous materials. If any machine damage is suspected, or the level of contaminant or wear metals have increased since the last filter inspection, a ferrographic analysis of an oil sample should be carried out.
Q | Do operators know if a machine’s
operating temperature has increased beyond normal?
LOGIC:Operating temperatures of industrial equipment are often unknown or @MROmagazine

The future of bearing related maintenance
What we are seeing is a move towards a situation where the operating facility changes out a complete assembly or asset, rather than just the bearing. BY DOUG MARTIN
18 MRO / Winter 2023
maintenance structure in Canada (or at least traditional heavy/primary industry) for the decades. That story is exemplified by the anecdotal evidence of new pulp mills built in South America in the late ‘80s early ‘90s. In these facilities, the maintenance department was a contractor. The pulp company was an entity that “made pulp” and any support “departments” were contractors. What does this mean for large facilities like the mine site? For several years, instead of changing a single
bearing on a belt conveyor pulley, the whole pulley is removed. In turn, companies who changed out whole motors when there is a bearing problem had their own motor shops, but now they use an outside motor shop. Today, we are seeing larger assets being changed out and rebuilt off-site by a contracted shop. Even the traditional bearing distributors have developed their own service centres, in which they rebuild these assemblies. It is the way they can continue to sell the bearings, MROMAGAZINE.COM

Recently, I visited a large mine site in Northern Canada on a day that layoffs were announced, and one of the maintenance personnel I was to meet, was one of the casualties. Driving on the site with my hosts, a discussion began about how they will have to depend more on suppliers for technical assistance. This comment clearly defines what may be the future of maintenance. However, this story is not new, it has been hanging over the traditional
seals, and other components, they once sold as individual parts, to the large users. What is the benefit to this transformation? It allows the mining company or pulp company to focus their attention on what they produce, and not trying to manage a maintenance department, or a rebuild department. It may also allow a higher level of quality control. They can write and enforce tighter quality controls over the rebuild than they were able to achieve within their own organization (especially in times when resources were strained). There are also some cases where recognized organizations or consultants will certify rebuild shops on behalf of users, in turn, giving a degree of confidence in quality of the job. Last month, while at a pulp mill assisting with a critical fan installation. One portion of the job was to balance the rotating assembly prior to installation.This is a critical aspect of the job.The rotating assembly was sent out to a sub-contractor and returned within a day. I later asked why the fan was not balanced in house, knowing that they likely had the equipment to do so. The reply was they may have the equipment, but when their crew may only balance two or three assemblies a year, they lack the expertise to do the job quickly and with a degree of quality.
maintained, and replacing any wires that may have been damaged. Another hurdle that condition monitoring/ vibration analysis systems face is the issue of security. Many of the latest technologies offered require an Internet connection to allow access to the software for the data analysis. The benefit of the online software is it removes the need for regular software release to be manually downloaded and installed (maintenance of system), and it allows collaboration within the organization. However, with recent data breaches and ransomware issues, IT departments have become very strict in who and what is allowed to be connected through the network. There are other condition monitoring technology that may provide an alternate. There are online systems that can connect to the local cellular networks and allow communication/data transfer with the cloud, outside of the company’s internal network. The user can access the vibration data through a secure web site that does not endanger the security of the IT system. In terms of less expensive systems, there is a move towards surveillance systems
E
as opposed to diagnosis systems. What a surveillance system can do is monitor basic parameters like overall vibration and temperature, and then with its AI, learn how that machine runs and warns the user there has been a change in the asset. This can lead to inspection and diagnosis of the problem with more complex tools (such as a route-based data collector). The benefit is shifting those in the vibration department from being data collectors to inspectors and troubleshooters of identified issues. I have identified the change that we are in the process of, not made any bold predictions. That is production facilities becoming streamlined, focused on production of their product, and not large organizations with different departments dealing with all aspects of the operation.They will be supported by local vendors and shops that have become experts in their specialty and have the quality systems in place to provide a high level of service.

FUTURE OF MAINTENANCE
FEATURE
Next generation of maintenance
MRO spoke with maintenance and asset management experts to get their perspective on what they see happening for the next generation of maintenance. BY MARIO CYWINSKI
MRO: What do you see as the biggest advancement in maintenance in the next five years? Ten years?
Hugh Alley: Five years, there will be more retrofittable sensors that will provide diagnostic data about equipment condition that will connect wirelessly. Some equipment 20 MRO / Winter 2023
manufacturers will start taking data security seriously, and more maintenance operations will be looking for secure connectivity; just being connected will no longer be enough. In 10 years - equipment manufacturers and maintenance service organizations will increasingly provide uptime as a service, as they leverage the data they gather. Richard Kunst: Sensors are getting cheaper, faster and have broader capability. Add to that how the bandwidth and speed of data highways has become, and we will see a migration from preventive maintenance to predictive maintenance through the early detection of subliminal abnormalities for quicker, cheaper, and easier repairs. It is now very cost effective to build several layers of redundancy within an automated system, repairs can be made without incurring any actual processing downtime. The coolest aspect is that we will be aware of a potential problem before we even physically realize it. Susan Lubell: In the next five years, we will continue to see step changes in the use of predictive maintenance for asset health monitoring. As sensors and condition monitoring becomes cheaper to install and can be placed in more hazardous environments, we will be gathering more asset health data on a real time 24/7/365 basis. This analysis will inform our decisions on run, repair, replace for physical assets, providing the information to decide when to maintain physical assets and what the scope of the repair will be. With the advancements seen in the last few years, 10 years out is too far to predict what new data and information the future technologies will enable.
James Reyes-Picknell: In the short term, competitive pressures are driving a push towards productivity and in all but new plant and equipment, they are struggling with reliability issues.This is causing an uptick in focus on reliability currently.Within the next five years, we will see a reset, going back to basics in both reliability (maintenance tactics) and in work management practices. Processes and systems are in place but are often used poorly and to little effect. The workforce has lost a lot of experience with the retirement of large numbers of people during and shortly after COVID-19. With relatively few baby boomers left, and in most cases, no attempts to capture their knowledge, companies are realizing just how much they depended on them. They are repeating old mistakes and realizing that they are not as systematic in their methods as they may have thought. In the longer term (10 years) we will see a shift towards outsourcing of maintenance in small, medium and some larger industrial operations. Attempts to fix the problems above will not be entirely successful due to an unwillingness to invest enough in maintenance, and the continued drain

Greek philosopher Heraclitus is credited with saying “change is the only constant in life.” In his time, the issues we are facing today in maintenance were not around. However, all this time later, the saying still holds true, and in turn, those companies who do not adapt to ongoing change, will be left behind. Many of the technologies that we are seeing in the world today, were only seen in science fiction movies years ago. Like the rest of the world, maintenance is constantly changing and evolving. Obviously, the core values remain, but how things are done, continues to change. We are seeing advancements in artificial intelligence (AI), use of data and diagnostics, moves to outsource maintenance, more focus on predictive maintenance, and focus on many other new technologies. MRO reached out to experts come from across the maintenance and asset management sphere, to get a complete look at what the future holds for the world of maintenance. They include Hugh Alley, president, First Line Training Inc.; Richard Kunst, president and CEO, Kunst Solutions; Susan Lubell, principal consultant, Steppe Consulting Inc.; James Reyes-Picknell president and principal consultant, Conscious Asset; and Cliff Williams, author, and asset management expert.

of experience. Realizing that they are not as good at maintenance as they want to be, and that they are seemingly incapable of managing changes, they will look to outside expertise - not in consulting, but to delegate the whole function. This will open the door to a big shift, particularly in North America, where outsourcing hasn’t been popular, from in-house management of maintenance and reliability to reliance on external specialists who treat it as a business, and not just a troublesome cost centre. Cliff Williams: Obviously AI and machine learning will be the advancements – how effective they will be in mainstream maintenance and reliability is the question. Many lack the basics of good maintenance and reliability, don’t appreciate, or use the data they have – or should have, so there is skepticism around how they will take advantage of the advancements. At the Society for Maintenance & Reliability Professionals (SMRP) Conference, there were more AI technology vendors than any others – but what they were selling was the technology and not necessarily the solutions. These will depend on @MROmagazine
the knowledge and understanding of what drives results in the maintenance and reliability organizations. It will also involve a lot of change in approaches, roles, responsibilities, and we’ve proven time and again to be lacking in change management.
MRO: How do you see AI affecting maintenance operations?
Alley: AI is about multi-dimensional pattern recognition. It demands very large datasets, which are only going to be available to organizations managing large quantities of equipment. This will create challenges for small organizations, which won’t have the analytical capacity, or the quantity of data needed. This will open opportunities for specialist maintenance services to aggregate data, through the better understanding provided by the data, they will be able to offer superior uptime to smaller operations. It will also open opportunities for manufacturers to provide monitoring services, and they will aggregate the performance data from the equipment they build, allowing them to tune where they make improvements and to provide better
guidance about maintenance needs. The manufacturers will therefore be able to develop ongoing revenue streams from sharing the results of a customer’s data with them. Kunst: First, AI is going to be a big benefit to user manuals to insure people properly start and operate machines. In many cases we fail to optimize the capability of our equipment because we get used to using only certain functions. Second, AI will be critical to early detect and resolve potential issues. With AI we can be constantly running diagnostics in the background, while the machine is operating, stealthily detecting, and seeking abnormalities and quietly switching to a redundant process while alerting the organization what and where to perform maintenance. Lubell: The vast quantities of data gathered are staggering. We will need AI techniques to build analytical models and frameworks to harness and analyze the data, turn it into information, and allow us to make business decisions. The maintenance operations space is no different. The Winter 2023 / MRO 21

increased collection of asset health monitoring data needs to be analyzed to be useful for business decisions and this will require AI.
MRO: Do you see any maintenance activities that will be eliminated in the future?
Alley: Routine monitoring activities will become less necessary as it becomes cheaper and easier to connect sensors wirelessly. Time-based preventative maintenance will be replaced by condition-based predictive maintenance. Kunst: If we gauge our maintenance efforts in the form of frequency and severity, I envision that severity will significantly decline due to better early detection of potential problems, before they can create a catastrophic consequence such as a machine breakdown. However, it would be reasonable to expect more minor maintenance requests being performed. The more data you feed AI the more effective your AI will assist you. Like CNC machining, where you can enter “tool wear parameter” so the machine will tell you when to replace 22 MRO / Winter 2023
a specific tool. We need to take a fresh look and develop parameters that we do not actively monitor, temperatures, amp draw, and vibrations, we have the detection technology, but have not created upper and lower control limits. Lubell: With the increased focus on predictive maintenance and asset health monitoring on a real time continuous basis, maintenance activities will shift to more analytics and interpretation of the data and information. The fundamental understanding and performance of maintenance activities won’t go away; however, the emphasis and time spent will shift to more analytic interpretation and deciding how to respond followed by more targeted repair strategies.
We already see that in the realm of electronics, where circuit cards and modules are swapped out to hasten repairs, without knowing if they are flawed. That will expand into the mechanical world, because of the loss of experience and expertise that is well in progress today. Sadly, what will be disappearing in many cases, is that ability to troubleshoot effectively. Williams: No, I hope not, we still see organizations that don’t do what they should be doing, the hope is that we don’t eliminate any activities, but progress to using the right ones for the specific situation.
MRO: What can facilities do to make themselves more technology-ready in the short Reyes-Picknell: Already we see term? Long term? less inclination to perform repairs at the component and assembly level in favour of swapping out parts and assemblies. Some assemblies still get repaired, but less by in-house shops. That trend will continue with two possible outcomes. For those who invest in the ability and knowledge needed to do effective troubleshooting, repair times are likely to shrink and that could potentially contribute to a drop in workload overall. For those who do not invest in those abilities and knowledge, it will lead to higher usage of parts and assemblies, as they are swapped out, not knowing if they need to be.
Alley: It’s all about developing your people. Maintenance staff will always need the wrenching skills, but they will need to know how to tap into the insights from large quantities of data. Those skills are unlikely to be available “on the street.” Hiring the skills, you need was more possible 30 years ago, when controls for most machinery and equipment were mechanical. If you knew how hydraulics and mechanical systems worked, you could fix just about everything. In the coming years that won’t work; every company’s specific needs will be different because their specific mix of equipment and products will be MROMAGAZINE.COM

Reyes-Picknell: As companies shift more towards installed sensors and non-human data gathering the quality of data will improve. This will enable more reliable performance of predictive/prognostic tools that are presently hampered by poor quality maintenance data, that often lacks the granularity needed to be used for reliability analysis. Deterministic algorithms that are in use will become more valuable as the quality of data feeding them improves. With more sensors and data, the door will open to data scientists who can apply more general analytic tools to finding relationships, correlations, and helping to identify where we may find causation of those correlations. We will still need to intervene in making those latter determinations as the analytics don’t “know” what’s going on aside from the numerics. This will all enable shifting towards greater reliance on condition monitoring and may reveal the correlation of excessive inspection work and overhauls to lower reliability to those who remain skeptical today. Reliability engineers will be increasingly needed, and in turn, they will need enhanced analytical/data science backgrounds.
Reyes-Picknell: In terms of IT and OT knowledge and skills, most operations have this already. Many have already deployed technologies that are underutilized or not utilized at all. The technologies that are available, have in many cases, exceeded the ability to use them to much effect. In fact, these systems are often generating work just keeping themselves going. The danger we face is not in lack of technical capability, rather it is in jumping to technological solutions before they really know what they are doing to do with them. I see a bit of “ready, shoot, aim” going on. There is need to do more “aim” and sooner, before deciding on technology and its rollout. It will be necessary to find and/or develop some expertise in production processes, equipment, and industrial systems (not just the IT), working together with maintainers, operators, and reliability engineers to help guide the need for and deployment of technology where it can do some good. unique. Consequently, companies will need to be able to learn these skills as they apply to each of their specific machines. They’ll also need to be able to retain and teach what they’ve learned as staff change over time. Meaning maintenance leaders will need to become better instructors, and better at the skills of developing scientific thinking. These are skills companies can start developing now, and they will have almost immediate payback. For leaders with these capabilities, the new technologies will present lots of opportunity.

Lubell: One of the areas that is starting to get more attention is asset and maintenance information management. We need to think ahead to what questions we want to answer in three or five years and structure our data to allow us to do this. Ask yourself, how complete is your asset register? Do you know what assets you own? Do you know the value that that they bring to your organization? Consider cost, risk, and performance in terms of safety, health, environment, economics, regulatory obligations, social and governance. Information is an asset by itself and needs to be managed as an asset, collecting data without a specific purpose quickly becomes overwhelming to manage and often ignored. @MROmagazine

Educate and inform all who will be involved and manage the change.
processes we employ, the measures we make, and the culture we build – it’s all about people. Updating equipment while employing the flawed practices won’t work, not having the right data or having a way of turning that data into knowledge and eventually into wisdom should be the starting point where we can then, with confidence, understand the asset that needs updating – and not before.
MRO: Anything to add?
Alley: Like many sectors, the world of maintenance is in the middle of losing large numbers of extremely capable technicians as baby boomers retire. A lot of knowledge is walking out the door. For many firms with limited maintenance management systems, this loss can be substantial. I have one client where the entire maintenance staff has turned over in two years and the new supervisor is having to rebuild the entire knowledge base of the facility. Organizations that can capture that knowledge before it leaves will have a significant leg up on the competition.While new technology can help, the underlying discipline of developing standard work depends on leaders who are committed to the objective of delivering reliable uptime, and who are able to convince business leaders of the necessity of maintaining their assets well.
MRO: Can you speak about the assets and those which need updating the most?
Lubell:We are seeing huge advances in the use of technologies, sensors, and data analytics to advance predictive maintenance and asset health monitoring. It’s important to make conscious decisions on what and how we will use the data collected, how we will analyze it, and the maintenance decisions that it enables. Otherwise, we will be drowning in data and starving for information, when we want to be in a position of gathering maintenance and asset data and turning it into information that allows for business decisions.
Reyes-Picknell: There is a lot of aged infrastructure in our “basic industrial” capability (old plants and equipment). Investment in these more basic industries has largely been directed overseas, allowing our capacity to age and degrade. The impacts of COVID-19 on supply chain were a wake-up call about globalization, too much reliance on just-in-time and excessive lean. The world is far less stable that it was just a few years ago. To sustain our capabilities, so that we are less vulnerable to global calamity and disruptions, we need to sustain that basic industrial capability and some of its capacity.
Reyes-Picknell: History repeats itself because of organizations failing to learn the lessons of the past. Don’t under-estimate the impacts of demographics on your workforce, your in-house expertise, your capabilities, and your capacity. Waiting too long to capture what knowledge remains will prolong the pain of reduced capacity and increase the likelihood of repeated mistakes. The younger workforce is smart, tech-savvy, and eager to learn, but quickly losing the experienced guidance you may still have.

FUTURE OF MAINTENANCE
FEATURE
Outsourcing maintenance – is it time yet?
If we ask finance and operational leaders what they think about outsourcing of maintenance, they will admit to being uninformed, therefore unable to give a fact-based answer. If we ask them about their desire for improved asset performance and lower costs, they are interested, but cautious about just how it can be achieved. Finance and operational leaders are aware of problems with maintenance are not going away. The availability of skilled workers is a massive problem globally. The loss of experience, as baby boomers have/are retiring, has resulted in a lot of guesswork and re-learning of old lessons. It has also left the workforce with less experienced middle management, who learned management from that older cohort. Those old school management techniques are not working well with the younger workforce, and the work ethic is different. Management techniques and provisions to accommodate it, have not adapted particularly well. Maintainers are often unhappy that they are treated as low value expense items and unworthy of investment. They are unhappy with inexperienced leadership that doesn’t listen. They do feel a sense of ownership, but seldom get the feeling that everyone who manages them shares that feeling. They want to see things improve but lack confidence in their management ability to affect it. If we ask maintainers and their leaders if they want to be outsourced, the answer is invariably no. Outsourcing has negative connotations that are not necessarily valid. For one, there is a perception that it isn’t core, meaning the function being outsourced is not 24 MRO / Winter 2023
important to the business. Core business functions are those that generate revenues, and in that sense, maintenance isn’t. Maintenance is neither core to most businesses, nor is it truly unique, with relatively few specialty activities that might be unique to the business (e.g. industry or asset specific skills and knowledge). Another connotation is it will result in lower pay, worse working conditions and it could result in the loss of employment.While this has happened when other functions such as IT, HR, accounting and marketing have been outsourced, that does not set a precedent for maintenance. Firstly, it is important to understand that outsourcing is not the same as contracting out.With outsourcing, the service provider becomes a business partner with the owner. A well-constructed outsourcing agreement will lower costs through efficiencies, but it will also result in enhanced revenues through improved asset performance. Both the asset owner and the service provider can benefit if the owner’s revenues improve because of performance improvements. To achieve that, it is imperative that the workforce be motivated to perform.That is not achieved through reductions in pay, working conditions, job losses, or any other disincentives. Unlike IT, HR and accounting, skilled maintainers are not available in big numbers at relatively low cost. They
are valuable, difficult to find and difficult to retain. While the maintainers an owner already has would be valuable, it is fair to say that they may also require additional training, particularly in processes (such as work management) that would change. They may require skills upgrading to use technologies that they were not using before, and to enable them to participate in determining what are the best maintenance tactics to be used in the systems with which they are already familiar. One thing a smart service provider would want to do, is to capture the lessons learned and use them. The sense of ownership over problems and performance could be enhanced as that would become the focus of the outsource service provider. A lot of the concerns about the current state can be addressed and indeed removed in an organization that made reliability and maintenance its business. If outsourcing were used, the service provider would need to have MROMAGAZINE.COM

control over the maintenance that is done, how it is done, and how it is supported. Successful proven practices in those areas would need to be brought to the table. Relying on the owner’s stores and purchasing could be a huge mistake, especially if it is not working well before outsourcing. At PEMAC’s MainTrain conference earlier this year, MRO did a roundtable discussion of the subject to see if perceptions could be shifted and to find out what concerns might exist. We had some very interesting feedback. We found that negative perceptions of risk were largely based on the perception that outsourcing would be like contracting out. In outsourcing, the contractual focus is on outcomes, not activities. In contracting, the scope is well defined, and often very prescriptive. Outsourcing should be based on a clear definition of the desired outcomes and leaving the “how to” to the creativity of the services provider. Imagine the potential if your service provider was specialized in delivering @MROmagazine
highly reliable equipment, rather than merely fixing something that has broken. Concerns about work quality and control over what is being done should disappear as results begin to materialize. Invariably, if the business case for outsourcing is substantial, there are very likely some quick wins that can be used to dispel some of these concerns. A concern was raised about the ability to meet collective bargaining agreement terms, which often include provisions for contracting. Without question, that will be a challenge to deal with, in most cases, but if the overall package, as experienced by the union member is an improvement, the hurdles become much easier to overcome. We heard that communications between maintenance and operations/production departments are already difficult and sometimes almost non-existent. There’s legitimate concern about whether a contractor could achieve better communications or worsen an already bad situation. Often this stems from unprofessional behaviors on the part of the operations
departments. There would be a need to have an enforceable contractual requirement and mechanism (based in good work management practices) to ensure the customer communicates. If problems arise, contractual remedies will need to be enforced. If that had to happen, the pressure from contracts on operations would likely be substantial and their ability to behave badly curtailed. If maintenance, reliability, condition monitoring, engineering, stores, and other personnel, were moved from the “owner” to the “service provider”, there would be a substantial change management challenge. They’d need to learn new ways of working and new systems.Training and coaching would be needed, and all while continuing to deliver the work they were doing before the transition. Both those who are, and are not outsourced, may feel a sense of loss that will need to be dealt with. On the part of those leaving, the overall conditions must be seen to be improving. The owner may need help in dealing with the feelings and Winter 2023 / MRO 25

motivations of those who are left behind and that should be built into the agreement. Business processes that may require participation of both parties will require attention. For example, if stores are outsourced but purchasing are not, then how will communications work. Many companies unknowingly rely on informal relationships and methods that “make up for” the inadequacies of their business processes and systems. Those need to be identified and managed in more formal ways if the full scope of what is needed to be done is not entirely outsourced. If things go wrong, particularly with asset performance, there would be tendency for finger pointing and defensive behaviours. The agreement must make provisions for what happens when performance isn’t up to expectations, including defining what that performance should be. Failures are often caused by human error, both on the part of maintainers (outsource service provider) and operations (owners). Dealing with failures and their causes must be done with an open mind and willingness to accept that the causes could be on one or both sides. More importantly, actions to eliminate causes must be 26 MRO / Winter 2023
mutually agreed and executed. In the short-term, costs could rise. Where there is likely to be a substantial business case for outsourcing, under performance is probably a big problem. A lot will need to change in processes, practices, and training, to turn that around with the same personnel who have just moved from the owner to the service provider.That has a cost. It is likely to be lower than the cost of the owner obtaining help to fix it themselves and deal with all the change management issues that will arise. Most operating companies are bad at that and tend to go far too slowly. They are not consultants, trainers, and masters of managing change; they are not set up to deal with it. Making the changes to gain the business benefits will be slow, much slower than with a competent outsource service provider that can bring experience and those skills to the table from the outset. Intellectual property could be a concern, in cases where production processes or formulations are secrets. Those would need to be dealt with in the agreement and through initiating controls.That said, it is worth pointing out that most maintenance skill and activity does not require knowledge of those secrets and that noting in terms of maintenance skills, knowledge and
practice is unique. The equipment itself doesn’t know the secrets, but it does respond to good maintenance practice when it is applied. Eventually, all equipment will reach the end of its useful life and become uneconomic to repair and maintain. Provisions will be needed for demonstrating where that is a concern and for handling of the capital investment. It would be unreasonable to expect a service provider to commit to reliable performance from equipment that has been under maintained, abused and allowed to deteriorate through continual deferral of needed maintenance. It would also be unreasonable to expect that all equipment be renewed frequently. These are some of the concerns and issues that will need to be dealt with. The challenge is substantial, but it is not impossible. Hurdles can all be dealt with intelligently and with feeling. The benefits that can be realized in the long term, could be well worth the pain of transition in the short term. Photo: Hero Images / Adobe Stock

Unplanned downtime costs businesses nearly quarter million dollars per hour BY MARIO CYWINSKI
Photo and chart: ABB
A survey from ABB has found that 68 per cent of industrial businesses in Canada experience unplanned outages at least once a month. The Value of Reliability survey found that this costs Canadian businesses $242,000 per hour, compared to $170,000 per hour globally. “There’s no typical length for an outage, but consider one that lasts a working day of eight hours – based on the median hourly rate, it would cost a business one million dollars,“ said Hugues Therrien, ABB Canada Motors and Drives Service lead. “With this in mind, industrial businesses should aim to progress from a high-risk run-to-fail maintenance approach to a long-term outcome-based strategy. This will improve reliability, business reputation, competitivity, cut costs, and provide peace of mind – empowering businesses to focus on their core competence.” The survey, which was conducted by Sapio Research in July this year, spoke to 3,215 maintenance decision-makers globally across many sectors. Interestingly, even with the high costs associated with downtime, the survey found that nearly one in five (19 per cent) of Canadian businesses still rely on run-to-fail maintenance.
@MROmagazine
Cover of the Value of Reliability: ABB Survey Report 2023.
Looking at things from a global perspective, 69 per cent of respondents have had unplanned downtime on critical equipment at least once a month (19 per cent a few times a month, 14 per cent several times a week, 14 per cent once a week, 13 per cent once a month, and eight per cent every day), with 14 per cent every quarter, eight per cent yearly, eight per cent less than once a year, and one per cent said never. Most (92 per cent) of respondents said maintenance has increased their uptime over the last year. Breaking it down further, 40 per cent increased by 10 to 25 per cent, 27 per cent by 26 to 50 per cent, 14 per cent by less than 10 per cent, and 11 per cent by over 50 per cent. Furthermore, 75 per cent of respondents said reliability has made many positive impacts on their business. Top priorities when purchasing equipment were reliability (46 per cent), safety (43 per cent), energy efficiency (41 per cent), compatibility with existing equipment (29 per cent), capital cost (25 per cent), total cost of ownership (23 per cent), uptime (20 per cent), recyclability/ circularity (20 per cent), installation
time (18 per cent), and hygiene (17 per cent). Many companies (60 per cent) plan to increase investment in reliability and maintenance in the next three years, with a third planning to boost spending by over 10 per cent. Why are companies putting additional focus on maintenance and reliability of their operations? When asked what the main benefits are, respondents said optimizing quality (43 per cent), ensuring product quality (43 per cent), extending equipment lifetime (39 per cent), avoiding downtime (37 per cent), energy savings (37 per cent), reliable supply to customers (35 per cent), avoiding extra costs (34 per cent), and minimizing waste (33 per cent). Looking into the future, respondents looked at what they believe will impact their maintenance strategy going forward. The top answers were circularity (67 per cent). energy efficiency (65 per cent), digitalisation/IoT/big data/AI (63 per cent), partnerships/supply chain/ collaboration (58 per cent), and augmented reality/VR/digital twin (47 per cent).

MRO Pro Tip Proactive desirable maintenance BY PAUL DAOUST
30 MRO / Winter 2023
MRO Pro Tip
The lost art of alignment BY HOUTAN GHAFFARISARAVI In today’s complex business environment, effective communication is critical for securing necessary investments in maintenance. Key strategies for conveying the importance of maintenance to decision-makers are: Utilize data-driven arguments: maintenance managers should present data and analytics to back their requests. Including historical maintenance records, downtime costs, and impact of maintenance activities on overall productivity. Demonstrating how proactive maintenance can save money in the long term, by preventing costly breakdowns, is a compelling argument for investment. Align maintenance goals with business objectives: it’s important to show how maintenance investments align with the broader business goals. Whether it’s increasing operational efficiency, ensuring compliance, or improving customer satisfaction, making the connection between maintenance activities and these objectives can help executives see the value in the proposed investments. -Develop a compelling ROI case: presenting a clear ROI case can be influential. This involves illustrating
how investment in maintenance will lead to tangible benefits, such as reduced operational costs, extended equipment life, or enhanced safety, which contributes to the bottom line. Use visual aids and reports: visual representations of data, such as charts and graphs, can be more effective than verbal or written descriptions. These tools can help executives quickly grasp complex information and the implications of maintenance activities. Communicate in business terms: speaking the language of business when communicating with executives is crucial. Meaning focusing on cost-benefit analyses, risk management, and strategic planning, not technical jargon. Share success stories and case studies: providing examples of successful maintenance investments from within the organization or from other companies, can serve as powerful testimonials to the value of proper maintenance. By employing these strategies, you can effectively communicate the need for maintenance investment to executives and decision-makers, ensuring the necessary support and resources for optimal maintenance operations.

One of our best maintenance metrics is work identification. Where did the work come from? Many organizations are stuck in a reactive maintenance regime. To them asset management means “fix my maintenance”. Here’s how. Proactive desirable maintenance should comprise about 80 per cent of our work hours: primary time and condition-based and predictive work with secondary work identified from formal tactics. Reactive undesirable maintenance should make up about 20 per cent of our work hours: breakdowns and all requested work that doesn’t stem from formal tactics. We avoid the term corrective work because it has both desirable and undesirable components. Immature maintenance organizations have a high degree of breakdown work.
