ABSTRACT

All earned value techniques rely on a well-conceived project plan. The project work must be clearly perceived at the start and well understood in terms of both what is to be done and the order it should be done. Sometimes these criteria cannot be met; the reasons could be:

• There is an extensive amount of experimentation involved. • The work is highly innovative with many uncertainties. • The strategy involves taking advantage of whatever opportunities may arise. • External forces are likely to dictate the course of the project.
