National Exams, May 2015 — 04-Soft-A5, Requirements and Specifications (open book, one book of the candidate's choice, 3 hours, no calculator). The paper has four parts: Part 1 (30%) is ten statement/reason items on requirements-engineering theory; Part 2 (25%) is a two-page essay on the requirements-elicitation process; Part 3 (25%) covers non-functional requirements, including three NFRs for a life-critical avionics system; Part 4 (20%) asks for the seven characteristics of an excellent individual requirement and the three characteristics of an excellent requirements collection. This solution answers every part and every sub-item in full as a study resource.
