Early Applications of DOE
- Started around Mid-1970 , pioneers : BHEL, Kirloskars, a few
Small industries at Bangalore
- Trained Engineers on Taguchi’s DOE but not Managers with a
few exceptions
- Late S L Kirloskar himself attended a Program on DOE. His
Curiosity knew no bounds
- Later Mr. Venu Srinivasan of TVS also took an intensive
training on Application of DOE
- Typical areas of applications: Yield Improvement using
- ptimization of process parameters (Insulator), Existing
product design optimization to reduce cost (Pump),Reliability improvement of Circuit Breakers, etc

Signal to Noise Ratio
- With S/N ratio we get a combined measure of average and
variation which is not the case in any other approach
- RQE approach helps us to optimize the output keeping minimum
variability thus maximizing robustness.
- S/N ratio has very good additive capability in quality
evaluation and prediction
- Taguchi pointed out that one of the advantages of using S/N
ratio is its direct link with economy; as S/N ratio is deduced from loss function
- Cost advantage as only few selected combination trails are
run
- STATIC VS DYNAMIC

Service Processes
- They also included service functions like logistics, SCM,
Finance to improve robustness with astounding resultss
- The IT/ITES did not fall behind with human dominant processes
- RBEI, L&T,Wipro, Capgemini ,came up with a few novel
applications
- Universal applicability was shown by CPG when for DMAIC/DFSS
Project , they are comparing S/N Ratio before and after
- All said and done just surface scrtching has started.
- Let’s discuss how to take it forward !
- We need trainers, guides and coaches-Can You Help?
