The application of business process re-engineering (BPR) generates a whole series of projects, which range from process improvement projects through to radical organisational transformation. In these larger projects, usually formulated as programmes of related change projects, it is often difficult to apply the conventional project management techniques of planning and control. The range of variables that need to change makes the definition and control of the scope of such projects difficult. BPR requires a more pragmatic approach in order to recognise the evolutionary nature of the scope of such projects. A blend of decision making, project definition and planning provides the method to support the changing shape of such programmes of projects.
