AN OVERSIMPLIFIED EXAMPLE

NASA PERT and Companion Cost System Handbook, Director of Management Reports, NASA, 1962

In this approach only the major phases of work effort which represent a significant dollar effort are selected as subdivisions of work. [The figure at right] shows an oversimplified example of this approach.
