This textbook shows how to develop the functional requirements of information systems. It emphasizes the importance to consider the complete development path of a functional requirement, i.e. not only the individual development steps but also their proper combination and their alignment. Even after decades of numerous bad experiences, many software development projects are still failing on at least one or even all three basic requirements for a project: - Too little (The project delivers inadequate functionality); - Too late (The project is not within time); - Too costly (The project is not within budget). Or, even worse, the project has been ended prematurely, usually after a lot of time and money have been spent, and without delivering any working functionality... The reasons for those failures usually lie at the very beginning: There is no clarity in what the customer really wants and needs, leading to incomplete and even wrong specifications, and subsequently programmers who fill in the functional gaps to the best of their own understanding. So, it is very important to get really clear what the customer wants and exactly needs and to make unambiguous, correct, and complete functional specifications. This book is written for (under)graduate students in software engineering or information systems who want to learn how to carry out adequate problem analysis, to make good system specifications, and/or to understand how to organize and manage an IS-development process.
