RE Tasks and Processes

Abstract

RE is a flexible process where activities and tasks can be mixed in many different combinations. So while there is no one “cook-book” method for requirements, the basic steps can be described and composed into a process depending on the application context being investigated. However, a single all-embracing RE cook-book method would not be desirable. RE has to fit into a range of different contexts, and integrate with existing development methods such as SSADM, the more recent object-oriented development methods and the unified modelling process. Consequently, this chapter will review the activities in RE as a set of tasks, and then present them as processes for different requirements contexts, i.e. variations according to the application being developed and the starting point of the requirements investigation.
