lem into sub-problems in a systematic manner. Each of the sub-problems is then dealt with separately, and the relations between the sub-problems are well defined. (b) Identi- fying the entities involved in each sub-problem and determining how they are related. An organized and systematic analysis of the problem should result in a structured develop- ment process; this serves as a basis for the initial stages of project development, such as
