DfSS : which methodology do you advocate?
Whilst researching the forthcoming onesixsigma.com special report on Design for Six Sigma, I was surprised at how many different process abbreviations are associated to it. Whilst Six Sigma has progressed with DMAIC remaining largely untouched, so far in my research I have found the following procedures all claiming to be the DfSS lifecycle accronym:
- DMADV : Define – Measure – Analyse – Design – Verify
- IDOV : Identify – Design – Optimise – Validate
- IDDOV : Identify – Define - Design – Optimise – Validate
- DMEDI : Define – Measure – Explore – Develop - Implement
- DCOV : Define – Characterise – Optimise – Verify
- DCCDI : Define – Customer – Concept – Design - Implementation
Which methodology do you advocate and why?
IDDOV or DMADV

IDDOV for new productsor processes and DMADV for transactional processes.
DFSS methods
Lay them all side by side and you will find, conceptually, they are all the same. There are very slight variations in the individual tasks, but as a whole they all do the same, but use a different acronymn. Don't lock yourself into a strict definition for each one...there isn't one. They all design a product or service using customer expectations, clarify how to measure performance, optimize, validate and implement.
