What is a Flowchart?
A flowchart is a planning and analysis tool. It is a graphic of
the steps in a work process.
When should a flowchart be used?
A flowchart should be used when a team needs to do one or more of the following...
- See how a whole process works
- Identify the critical points, bottlenecks, or problem areas in a process
- See how the different steps in the process are related
- Identify the "ideal" flow of a process from start to finish
- Design a new work process
How should a flowchart be constructed?
Follow these basic steps in completing a flow chart...
- Agree on the work process needing the flowchart.
- Agree on the beginning and ending point of the work process. This helps to keep the team focused.
- Brainstorm the major steps in the work process. Do not worry about the sequence at this point.
- Put the major steps in the proper sequence. As this is done, the team may begin to add minor points.
After all steps have been identified and sequenced,
- Assign the appropriate symbols to each step. (See below)
- Connect the steps with arrows to show the flow of the process.
- Test the flowchart to make sure all the necessary steps have been included.
- Finalize the flowchart.
Three types of flowcharts:
- A process flowchart is the most familiar type. The process flowchart moves through the process from start to finish. It is most useful when analyzing a specific function or activity where there is no need to identify customers and/or suppliers.
- A deployment flowchart is useful when analyzing a process
that involves more than one department or several individuals.
- When a process calls for a deployment flowchart, it may first be helpful to construct a process flowchart with only the major steps and then modify it by assigning the appropriate departments or individuals to each step.
- The top-down flowchart starts with the major steps drawn horizontally. The detail is provided in numbered subtasks under each major task. The top-down flowchart does not show decision points reworks and so on and therefore is not as detail as the process or deployment flowchart.
