In analysing processes, particular actions along the way are often significant, especially if you are looking to eliminate sources of waste (or muda, as the Japanese call it) such as having documents piling up in in-trays or materials being moved from pillar to post.
How it works
The Flow process Chart is a simple half-text, half-picture method of showing the steps in a process, using symbols to indicate the type of action being taken and text to give details of the action. The chart can selectively be used to show what happens to selected people, materials or equipment.
Parts of a Flow Process Chart
A particularly useful feature of the chart is that it can be drawn up as the process is happening. Thus you can follow a part around a factory floor, for example, noting how and when it is machined, stored, moved, etc. The table below shows many of the symbols that may be found in Flow Process Charts.
