~ ~ The design is a logical view which is used as a guide for implementing a system. Although the actual system may differ in many ways from the design, the design is the initial blueprint. Most of the decisions which have to be made in order to implement the complete system are made during the design phase. A properly designed system is easier to implement, because the communication strategy has been determined, and the problem decomposed. With the problem decomposed, the individual smaller pieces can be implemented. The screen layout is needed to simplify the task of building the pieces of the screen. The interactions between various parts of the screen have to be determined before they can be built individually. The difference between the design and the implementation of SNEAKERS is described in the next chapter.
