Chapter 3 Modules “Not everything that can be counted counts, and not everything that counts can be counted.” Albert Einstein.
Modules of an Information System Any information system must be built with enough flexibility to accommodate the specific needs of the project, but at the same time must comply with basic standards that make analysis of the project progress available at all levels of management. Depending of the nature and information complexity of each project, the system will contain a basic core or central module that structures the project’s basic set of information. Each project can then add more complex processes and modules as the specific needs of the project may require it. A PIMS is designed using a modular approach; each module provides a specific functionality and meets a specific goal. The modular approach allows for a structured method to develop and grow the information system based on needs. It also takes into consideration the integration of the different modules with each other to improve the management of information and eliminate redundancies.
An Integrated Approach Most project-information systems are built independent of each other, each designed to specific needs, and each project has a different definition of how to structure information. For example, a project health-information system
