Suppose you are involved in a large project concerning the development of a patient planning system for a hospital. You may opt for one of two strategies. The first strategy is to start with a thorough analysis of user requirements, after which the system is built according to these requirements. The second strategy starts with a less complete requirements analysis phase, after which a pilot version is developed. This pilot version is installed in a few small departments. Further development of the system is guided by the experience gained in working with the pilot version. Discuss the pros and cons of both strategies. Which strategy do you favor?
