Flow Charts
— Arrange
events in the order of their actual or desired occurrence (flow)
— Eliminate
wasted steps and activities (work simplification)
— Are
useful for identifying task components and in TQM
— Potential
problems: They do not indicate the time dimension of tasks.
They are not practical for complex operations where
several activities occur at once
A Sample Flow Chart
Gantt Charts
A graphic scheduling technique historically used in
production operations. Useful for scheduling large projects where time for each
activity can be specified and progress assessed. Potential problem: Overly
complex endeavors are too cumbersome for Gantt charts.

Program Evaluation and Review Technique (PERT)

Developed in 1958 for use in the development of the
U.S. Navy’s Polaris submarine-launched missile project. Graphic sequencing and
scheduling tool for large, complex, and nonroutine projects.
