Flowcharts are maps or graphical representations of a process. Understanding flowchart is necessary to improve a process. The designer needs to understand the flowchart operation and flowchart symbols in detail.
There are many varieties of flowcharts and scores of symbols that you can use. Experience has shown that there are three main types that work for almost all situations:
High-level flowcharts map only the major steps in a process giving a good overview.
Detailed flowcharts show a step-by-step mapping of all events and decisions in a process.
Deployment flowcharts organize the flowchart by columns, with each column representing a person or department involved in a process.
The trouble spots in a process usually begin to appear as a team constructs a detailed flowchart.
