Selected Projects with References We would like to briefly introduce you some of the projects we have worked on with the references:

RAIFFEISEN BANK AUSTRIA Overview: Raiffeisen bank Austria and McKinsey & Company approached us with a request to develop and set up the infrastructure for an internal project to be used in their banking environment. The goal was to create a simplified version of Raiffeisen bank’s existing banking software, to be used for training employees and monitoring their internal processes. In a challenging pursuit with time and under a very tight schedule (3 weeks), we delivered a working solution, fully-compliant with strict banking standards set by the client.

Based on the client’s satisfaction, our cooperation with Raiffeisenbank Austria has continued on further extensions to the system after the initial pilot.

Technologies used: Python with Pyramids framework, JQuery with JavascriptMVC framework, PostgreSQL, ArchLinux, DebianLinux.

“If all projects built by external developers were developed as well to specification, as quick, and as inexpensive as this one, innovation and advancement in banking would be a lot faster.”

– Ulf Wallman, Product Manager Raiffeisen Bank Austria

Execution methods and planning Our preferred way of approaching client projects is Agile. Having a track-record of more than a dozen of successful Agile projects, our team has a strong preference for working this way; however we are open to different ways of cooperation if required by the customer.

Our approach to planning We acknowledge there are multiple approaches to planning within the existing portfolio of agile methodologies. We are open to follow any of the standard methodologies you would recommend, otherwise we use our company default.

Types of plans. Commonly, we hold two levels of plans for a project: a project plan (broken down into sub plans for milestones/releases if needed) and iteration plans.

Deadlines given by business requirements, along with our initial range estimates are what drives the design of the project plan. As the project progresses, we further elaborate the plan into more detailed, and accurate, iteration plans.

Planning iterations. We regularly engage with the client in a discussion what should we build in the next iteration(s).

Given there are no specific preferences and functional dependencies, we prioritize the epics in our backlog according to the assessed technological risk embraced within the requirements for the epic. This way we are able to collect quick feedback on technologically uncertain parts of the project scope1, rule out the uncertainties early and thus improve the predictability of the overall project plan.

Once the user stories for the next iteration are selected, we start committing to final time estimates. Leveraging the most current knowledge about the codebase, functional dependencies and other emergent factors, we are able to give a specific number of hours required by each user story. We guarantee that this number falls into the range given by the initial estimates.

In case these estimates don’t fit into the time box of the planned sprint, we are always ready to make managerial decisions about resources and scope.

E.g. integration with 3rd party APIs or complex business logic

May interest you: The 95% confidence interval for our iteration estimates is currently at +/-25% of hours worked, averaging on a factor of +1.07 (based on 10 latest iterations on a project team of 5-7 members).

Risk management. Unless we deal with a large or complex project, we only work with simple risk management plans. For small projects we prefer holding an upfront open discussion about the perceived risks with all stakeholders, aiming for a common understanding what the risks are, what is the likelihood of them happening, and what are the strategies for mitigating the risks.

Monitoring. Within iterations, we hold regular stand-up meetings every day where the whole team plans for the following day. This way, the person responsible for the management of the project from our side is able to quickly react on whatever problem may arise.

Our approach to Quality Assurance For Quality Assurance reasons we enforce the following processes: • We unit-test our code. Depending on the complexity of the code we aim for high code-coverage by automated tests. Having all the business logic tested is the entry level of QA we are willing to work on.

• We create automated component, integration and API tests as an integral part of the development process.

• We use GitHub/Bitbucket for pull-requests. This means, at least two pairs of eyes see the code before pushing into the version control system. As a complementary activity we regularly engage developers in pair coding sessions.

• We have a dedicated functional tester, who engages in simulated UAT, exploratory testing and also regression testing upon the end of every iteration.

Our approach to Communication We prefer open, regular and constructive communication with all the relevant stakeholders on the project, either digitally (Skype calls, e-mail, phone calls) or face to face.

7

Our approach to on-site work In our experience, it is beneficial to the success of the project if clients’ internal developers connected to the project are on-site with our team, at least for the beginning of the cooperation.

In case that the client decides to have his employees or external consultants connected with the project working on-site with our team, we are happy to provide them with adequate working space at our offices in Bratislava, Slovakia on our expenses.

We are also willing to have our team work from the clients’ premises, however extra charges apply.

Our approach to Licensing and Intellectual Rights All rights to the deliverables and also the source code of the project are transferred upon iteration acceptance to the client in the full possible manner allowed by the governing law under which the partnership agreement is signed. We do not reserve the right to resell or otherwise use any of the work that is made specifically for the client purposes.
