                                               FLOWCHART

A flowchart is a diagram that describes a process or operation. It includes multiple steps, which the process "flows" through from start to finish. Common uses for flowcharts include developing business plans, defining troubleshooting steps, and designing mathematical algorithms. Some flowcharts may only include a few steps, while others can be highly complex, containing hundreds of possible outcomes.

Flowcharts are a methodology used to analyze, improve, document and manage a process or program. Flowcharts are helpful for:

1.    Aiding understanding of relationships among different process steps

2.    Collecting data about a particular process

3.    Helping with decision making

4.    Measuring the performance of a process

5.    Depicting the structure of a process

6.    Tracking the process flow

7.    Highlighting important steps and eliminating the unnecessary steps
