Book excerpt: This book provides a hands-on introduction to model-based requirements engineering and management by describing a set of views that form the basis for the approach. These views take into account each individual requirement in terms of its description, but then also provide each requirement with meaning by putting it into the correct 'context'. A requirement that has been put into a context is known as a 'use case' and may be based upon either stakeholders or levels of hierarchy in a system. Each use case must then be analysed and validated by defining a combination of scenarios and formal mathematical and logic-based proofs that provide the rigour required for safety-critical and mission-critical systems.
