Problem Concentration Diagram is used to show the location the issue is occurring. It can be very useful information during problem solving activities, to help identify the root cause of an issue.

Process when Using a Problem Concentration Diagram

A simple step by step process for how to use the Problem Concentration Diagram during problem solving is outlined below.

  • Define the fault or issue being investigated
  • Print out a drawing of the part being investigated
  • Every time the fault being investigated occurs, mark it on the diagram where it is located.
  • After a while when enough data have been collected, analyse the diagram to see where faults occur or if there is a pattern.

How to use Analyse Concentration Diagrams

After data have been collected, the diagram gives a good visual picture of where the issue occur. The diagram also gives information on where the issue is most likely to occur if recorded in more than one location due to the density of the marks.
During the root cause analysis of a problem, this information could for example be used to identify if the marks on a part came from a specific jig or fixture.

Areas of Use

Concentration diagrams can be used in different areas and for various purposes. Some examples could be concentration area of accidents within a company area, concentration of a particular animal outlined on a map, in the weather forecast it is also often seen indicating areas with storms lightning etc.
They are easy to use and effectively provide clear information in a visual manner.
