....consistent and relevant. The aim of RE in the waterfall model is to help to know what to build before system development starts in order to prevent costly rework. This goal is based on two major assumptions: The later mistakes are discovered the more expensive it will be to correct them [KS97]. It is possible to determine a stable set of requirements before system design and implementation starts. In the following, we will briefly examine the requirement engineering process and discuss the main techniques that were developed for it. 2.2 Requirements Engineering process The RE ....
....set of requirements before system design and implementation starts. In the following, we will briefly examine the requirement engineering process and discuss the main techniques that were developed for it. 2. 2 Requirements Engineering process The RE process consists of five main activities [KS97]: Elicitation . Analysis and Negotiation . Documentation . Validation . Management They can be presented in di#erent models. The most popular models are: 1. The Coarse Grain Activity Model (see Figure 1) The cloud icons indicate that there are no distinct boundaries between the ....
