    1. High Level Design and Software Architectures

    2. 2 Semester 1, 2008 THE AIM OF SOFTWARE DESIGN Requirements Analysis should yield a description of all the systems that would meet the clients needs and only systems that would meet the clients needs. Design should yield a description of exactly one system that will meet the clients needs. The difference is in design decisions: requirements analysis should avoid making them, while design should not leave any significant design decisions unspecified.

    3. 3 Semester 1, 2008 THE DESIGN PROBLEM If requirements are about what the system must do then design is all about how the system will do it. The Design Problem is to develop a description of a system that can feasibly be implemented by the developers and, if implemented, will meet all of the requirements.
