ASSIGNMENT TITLE : -
TAGUCHI APPROACH

3. 1. Background of the Taguchi Method.
2. Taguchi Design of Experiments.
 Robust Design
3. Taguchi Experiment – Steps.

4.  Born in Japan, 1924
 Electrical Engineer
 2nd name of “Taguchi Method” is “Robust Engineering”

5. DOE is an important tool for designing processes and
products.
Many factors/inputs/variables must be taken into
consideration when making a product especially a brand new
one.

6.  “Products and services should be designed to be inherently defect
free and of high quality”
 A three step method for achieving robust design (Taguchi)
1. Concept design
2. Parameter design
3. Tolerance design

7. Problem
Identification
•Managers and employees see that need
improvement?
Brainstorming
•Identify critical variables in the service that
affect quality.
Experiment
Design
•Using results from brainstorming session,
facilitator will design an experiment.

8. Experiment
•Facilitator, although in charge of the
experiment.
Analysis
•Factors closest to target specification
identified.
Confirm
Experiment
•Set up new system using data from
experiment.
