Method-based requirements analysis
Most widely used approach to requirements analysis
- Depends on the application of some structured methods to understand the system
- Results are expressed in a set of system models
- Methods have different emphases: some are focused exclusively on requirements elicitation/analysis, others are very close to design
Structured methods usually include:
- Process model (dataflow analysis, control scenario identification)
- System modelling notations (diagrammatic, form-based, linguistic)
- Rules applied to the system model
- Design guidelines
- Report templates
