Requirements

The business requirements coming from customers are formalised and analysed during this workflow. It produces a business concept model and a use case model. The former is a conceptual model of the business domain and creates a common vocabulary between customers and developers. It is, however, not relevant for QoS Analysis. The latter describes the interaction between users (or other external actors) with the system. It establishes the system boundaries and a set of use cases that shall fulfill the functional requirements. In the PCM, the use case model is called usage model (see Section 3.5).
