  1. The requirements engineering process discovery documentation checking

  2. Modeling • What is a model? • A model is a simplification of reality • Every system may be described from different aspects using different models. Each model provides an abstraction of the system from a different perspective • A good model includes those elements that have broad effect and omits those minor elements that are not relevant to the given level of abstraction

  3. Principles of Modeling The choice of what models to create has a profound influence on how a problem is attacked and how a solution is shaped

  4. Principles of Modeling Every model may be expressed at different levels of precision
