What is a Cause-and-Effect Diagram?
A Cause-and-Effect Diagram is a tool that helps identify,
sort, and display possible
causes of a specific problem or quality characteristic
(Viewgraph 1). It graphically
illustrates the relationship between a given outcome and
all the factors that influence
the outcome. This type of diagram is sometimes called
an "Ishikawa diagram"
because it was invented by Kaoru Ishikawa, or a "fishbone
diagram" because of the
way it looks.
When should a team use a Cause-And-Effect Diagram?
Constructing a Cause-and-Effect Diagram can help your team
when you need to
! Identify the possible root causes, the basic reasons, for
a specific effect,
problem, or condition.
! Sort out and relate some of the interactions among the
factors affecting a
particular process or effect.
! Analyze existing problems so that corrective action can
be taken.
Why should we use a Cause-and-Effect Diagram?
A Cause-and-Effect Diagram is a tool that is useful for
identifying and organizing the
known or possible causes of quality, or the lack of it. The
structure provided by the
diagram helps team members think in a very systematic way.
Some of the benefits
of constructing a Cause-and-Effect Diagram (Viewgraphs 2)
are that it
! Helps determine the root causes of a problem or quality
characteristic
using a structured approach.
! Encourages group participation and utilizes group
knowledge of the
process.
! Uses an orderly, easy-to-read format to diagram cause-and-
effect
relationships.
! Indicates possible causes of variation in a process.
! Increases knowledge of the process by helping everyone to
learn more
about the factors at work and how they relate.
! Identifies areas where data should be collected for
further study.
