INF370Question 1 You are a software engineering manager and your team proposes that model-driven engineering should be used to develop a new system. What factors should you take into account when deciding whether or not to introduce this new approach to software development? Answer: The factors that you have to consider when making this decision include: 1. The expertise of the team in using UML and MDA. (Is expertise already available or will extensive training be required.) 2. The costs and functionality of the tools available to support MDA. (Are tools available in house or will they have to be purchased. Are they good enough for the type of software being developed) 3. The likely lifetime of the software that you are developing. (MDA is most suitable for long-lifetime systems) 4. Requirements for high performance or throughput (MDA relies on code generation that creates code which may be less efficient than hand written code) 5. The long term benefits of using MDA (are there real cost savings from this approach) 6. The enthusiasm of the software developers. (are all team members committed to this new approach) Question 2 Software specification Software specification is the process of establishing what services are required and the constraints on the system’s operation and development.√ Therefore, the requirements engineering process include the following: 3 | P a g e 4 | P a g e • Feasibility study: Is it technically and financially feasible to build the system? √ • Requirements elicitation and analysis: What do the system stakeholders require or expect of the system? √ • Requirements specification: Defining the requirements in detail√ • Requirements validat5 LATEST EXAM PACK
