Cause and Effect Diagram
• Displays the factors that are thought to affect a particular
output or outcome in a system
• Also known as an Ishikawa Diagram or Fishbone
The diagram helps show the relationship of the parts (and
subparts) to the whole by:
• Determining the factors that cause a positive or negative
outcome (or effect)
• Focusing on a specific issue without resorting to complaints
and irrelevant discussion
• Determining the root causes of a given effect
• Identifying areas where there is a lack of data

Force and Effect Chart
• Is designed to identify barriers to agreement among
team members concerning a specific situation.
• It combines features of the cause and effect diagram
with the dialogue of a force field analysis
•
Using the traditional “fishbone” structure, the right side
of the header bone identifies barriers to attaining the
desired effect, while associated left side entries describe
possible solutions to minimize the barrier identified on
the right hand side of the “bone.”

Solution and Effect Diagram
• A derivative of the cause and effect diagram
• Analysis is now focused on a solution rather than the
cause
• The Solution and Effect Diagram is useful when a
problem solving team needs to consider the complexity
of a proposed outcome and take an objective look at all
the contributing factors.
• Use of the structured fishbone leads participants to
consider both the primary and secondary solutions to a
problem by delving into the details in more depth.

Success and Effect Diagram
• A quality improvement tool used to analyze a successful
process
• Use the Success and Effect Diagram to understand
successful processes as insight into improving other
processes.
• When the Success and Effect Diagram is finished, the
next step is to decide what few “What’s” to expand upon
to support the team in future improvement efforts. This is
a case of playing to your strengths.
