Plan-driven and agile processes Plan-driven processes are processes where all of the process activities are planned in advance and progress is measured against this plan. Process descriptions may also include: Products, which are the outcomes of a process activity Roles, which reflect the responsibilities of the people involved in the process Pre- and post-conditions, which are statements that are true before and after a process activity has been enacted or a product produced. Software process descriptions When we describe and discuss processes, we usually talk about the activities in these processes such as specifying a data model, designing a user interface, etc. It presents a description of a process from some particular perspective. A software process model is an abstract representation of a process. Many different software processes but all involve: Specification defining what the system should do Design and implementation defining the organization of the system and implementing the system Validation checking that it does what the customer wants Evolution changing the system in response to changing customer needs.

The software process Software process: a structured set of activities required to develop a software system. Topics covered Basic software process models (1, 2, 3) Process activities Coping with change & additional software process models (4, 5) The Rational Unified Process (6) An example of a modern software process.
