At the start of a project, a proven engineering management plan should be used to control the critical path of the project.

• Requirements definition
• Concept
• Detail
• Implementation
• Production
• Customer

The above chart outlines on the steps in progressing a project from its inception to its implementation.

It is shown that the control of the projects’ costs and risk are best achieved from the inception of the project using modeling techniques.

The project modeling is integral to achieving success.

If the modeling is not comprehensive, it will add costs and risk from the middle to the end of a project and to the output efficiency of the project.
