Cause and Effect Matrix:

 Used to understand the relationship

between causes and effects.

 Consists of a two-dimensional array.  It will help:

• Determining the nature the problem.
• Prioritizing potential causes.
• Minimizes the need for more expensive statistical evaluation
• f inputs that are unlikely to have an impact on the output.
• Cause and Effect Matrix

Approach:

 Identify the problem and the possible causes (Fishbone diagram).  The (X’s) will be listed along the left side of the matrix.  The (Y’s) will be listed along the top of the matrix.  The (Y’s) are then ranked in terms of importance.  The relationship between causes and effects are ranked and an

• verall score is calculated.

 The causes with the highest overall

score should be addressed first in improvement efforts.

Example – Explore the Process of Doing a Load of Laundry:

 The “Critical to Quality” factors for the process:  Clean clothes.  Clothes smell good.  Wrinkle-free.  No shrinkage.
