The term “project life cycle” is misleading, because it is neither a perpetual circle of events nor the sequence of events rigidly fixed.
There are five stages to the project life cycle:
The five stages usually occur in sequence. If the project is relatively simple and there is no need to rethink or re-plan the project, the sequence of stages may be as simple as that depicted above.
If there are problems with the original project plan, then the controlling function leads back to planning. Execution may be delayed while additional planning takes place or may continue during re-planning. The new or modified project plan is then executed. During execution controlling processes are undertaken to ensure that the correct work results are being achieved.
Below is a project life cycle that has been forced by problems to return to planning.
During large complex projects it is often necessary to return to planning several times. In this case, the project life cycle can become very complex with multiple repeats of planning and even initiating processes.
The following is an illustration of a complex project life cycle involving multiple returns to the drawing board.
