DSDM Lifecycle Overview
DSDM provides a project lifecycle as well as a system lifecycle. Development projects are not the full story in the life of system. There are activities that occur before a project even starts and after it has completed, i.e. once a system is in use. These are contained in the following DSDM phases:
The project lifecycle is illustrated below:
The project lifecycle is not mandated and is expected be tailored to meet the requirements of a particular project, hence it is called the development process framework.
The development process framework is based mainly on Principles I, III, V and VIII. There are five project phases within DSDM:
-
Feasibility Study
-
Business Study
-
Functional Model Iteration
-
Design and Build Iteration
-
Implementation
The diagram shows an incremental prototyping approach moving anti-clockwise from the top. Dark arrows show the transfer points from one phase of the lifecycle into the next. The light arrows show the points where the development can easily return to an earlier phase.
