Hi Ronaldo,
All the requirements are characterized as use cases (for functional requirements) or supporting (for non-functional) requirements. Artifacts like the glossary and conceptual model support the understanding of requirements (as well as development), but are not considered requirements by themselves. For example, the definition of a term doesn' t indicate how the system must perform, or how it can be tested. But that term may be used in the context of a requirement, which is written to be unambiguous, testable, and understandable. Artifacts like prototypes prove technology, get feedback from the customer, etc. But they don't describe, in an unambiguous way, how the final system should perform. For that you need some form of well written statements that the stakeholders and development team can understand and agree on. OpenUP uses use cases and supporting requirements to achieve this. There are other methods of course, such as user stories or writing a bunch of discrete requirements. - Jim ____________________ Jim Ruehlin, IBM Rational RUP Content Developer Eclipse Process Framework (EPF) Committer www.eclipse.org/epf email: [EMAIL PROTECTED] phone: 760.505.3232 fax: 949.369.0720 ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of "Ronaldo r" <[EMAIL PROTECTED]> Sent: Tuesday, June 05, 2007 7:00 AM To: epf-dev@eclipse.org Subject: [epf-dev] system requirements The Supporting requirements concept mention that supporting requirements + use cases define the requirements of the system. This means that the Glossary, conceptual model (entities in a class diagram) and Prototypes doesn't define the requirements of the system? Why this other requirements are out? ----- Supporting requirements and Use Cases, together, define the requirements of the system. These requirements support the features listed in the Vision statement. Each requirement should support at least one feature, and each feature should be supported by at least one to requirement _______________________________________________ epf-dev mailing list epf-dev@eclipse.org https://dev.eclipse.org/mailman/listinfo/epf-dev
