Answer THREE questions. All questions carry equal marks.
Q1. “Prescriptive process models define a distinct set of activities, actions, tasks, milestones, and work products that are required to engineer high-quality software. These models are not perfect, but they do provide a useful roadmap for software engineering work.”
Describe the prescriptive process models and discuss their advantages and limitations. (33 Marks)
Q2. “Agile methods are far superior to traditional development approaches, and will finally result in projects that meet time and budget constraints while still delivering what the customer wants.”
Discuss this statement. In your answer you can refer to particular agile methods, e.g. XP and Scrum. (33 Marks)
Q3.
a) “Formal methods allow a software engineer to create a specification that is more complete, consistent and unambiguous than those produced using conventional methods. “
Discuss the above statement. Use examples, where appropriate, to support your answer. (16 Marks)
b) “Cleanroom software engineering is an approach that emphasizes the need to build correctness into software as it is being developed. Instead of classic software development life cycle it suggests a different approach. “
Discuss. (17 Marks)
