Notes and key points
-
Relative weight points must total 20 and be distributed across listed customer satisfaction product/service characteristics.
-
Perceived value/quality ratings are assigned a value from 1 to 5. A rating of 1 = poor; 2 = fair; 3 = good; 4 = very good; and 5 = excellent.
-
The lowest rating total is 20 (all 20 relative weight points value/quality ratings of 1); the highest rating total is 100 (all 20 relative weight points value/quality ratings of 5).
Step-by-step procedure
-
STEP 1 Customer feedback data is examined to identify problem areas for certain products or services.
-
STEP 2 The team develops a customer profile for the product or service under analysis.
-
STEP 3 Next, customer satisfaction characteristics of the product or service are identified and placed on flip chart.
-
STEP 4 The team facilitator draws a customer satisfaction matrix on a flip chart and inserts all characteristics. See example Lawnmower Repair Service.
-
STEP 5 The team then discusses the importance of each characteristic and assigns a relative weight to it.
-
STEP 6 Next, consensus is reached on a value/quality rating for each characteristic.
-
STEP 7 Finally, the facilitator calculates weighted ratings for each characteristic and arrives at a rating total.
-
STEP 8 The team checks all calculations; the customer satisfaction matrix is dated and given to the process owners for consideration and action.
