In this first assignment, TWO software development methodologies will be examined using the first four laws given in the prescribed text.

Glass’ law Requirement deficiencies are the prime source of project failures. (LI)

Boehm’s first law Errors are most frequent during the requirements and design activities and

Boehm’s second law: In Agile software development, each iteration acts as a prototype of the actual system, and hence user can easily identify the potential problems in the early stage of development. The initial prototype of the system helps the development teams identify the initial set of requirements to start working with. They develop the prototype to capture the requirements and then in each iteration a small number of new requirements are developed and delivered to the customer to get their feedback. If there is a problem in the interface the customer sees it as soon as a new iteration is completed and can easily get it corrected.

Davis’ law: In Agile software development methodology the importance is put on the working software delivered to the customer and all the activities revolve around this. The models are made just to understand and communicate some concepts about the software to be developed. These models can be detailed enough to expand the whole wall of an office or it can be a simple diagram to tell other developers how one has tackled some specific problem. The purpose remains the same; i.e. to help understand and build the system. Any level of model can not be a substitute for everything. There is no “One size fits all”.

2. Your first task is to describe each software development methodology clearly and completely in your own words. You may use diagrams, examples or UML to help you do this. [2 + 2 = 4
