Analyse the Case Study documents and determine the non-functional requirements (NFRs) or system quality attributes necessary to meet the needs identified in the Case Study. Document your analysis with a System-Wide Requirement document. Make sure your document addresses: a) Required system functionality not captured by a single use case (eg auditing, printing, authentication). b) The FURPS+ categories of system attributes. c) Any required system interfaces with external systems. d) Any business rules that must be applied. e) Any constraints that will affect the design of the system.
