Requirements engineering (RE) [1] is the process of defining, documenting, and maintaining requirements [2] in the engineering design process. It is a common role in systems engineering and software engineering .
Like all non-functional requirements and quality attributes, [6] architecturally significant requirements should be specified SMART. Quality attribute scenarios [2] are one way to achieve the S (specific) and the M (measured) criteria in SMART. The Software Engineering Institute recommends Quality Attribute Workshops for this effort. [7]
The PMI guide Requirements Management: A Practical Guide recommends that a requirements tool should be identified at the beginning of the project, as [requirements] traceability can get complex and that switching tool mid-term could present a challenge. [3] According to ISO/IEC TR 24766:2009, [4] six major tool capabilities exist:
For example, a maximum development cost requirement (a process requirement) may be imposed to help achieve a maximum sales price requirement (a product requirement); a requirement that the product be maintainable (a product requirement) often is addressed by imposing requirements to follow particular development styles (e.g., object-oriented ...
