Overview of Design For Six Sigma..

Evolution of Six Sigma..

Define •Who is the customer and what their needs.

Measure •How is the process defined and how are defects measured.

Analyze •What are the most important causes of the defects.

Improve •How can the causes of the defects be eliminated.

Control •What actions are needed to sustain improvement.

Conventional Six Sigma methods (DMAIC) have focus on solving existing problems (‘find’ and ‘fix’ continuous improvement)

Design For Six Sigma method focus on problem prevention and customer satisfaction (“design quality in”). We implement DFSS by adopting the IDDOV methodology.

Identify• Identify opportunities.(Project

charter, project plan, business case)

Define• Define Customer & Functional

requirements.(VOC, Kano Analysis, CTx, QFD, HOQ, Design Scorecard.

Design• Convert requirements to design

concepts.(Creative thinking tools, TRIZ, Pugh Method, DFM/A, Design FMEA)

Optimize• Find optimal/robust

settings/tolerances.(P-Diagrams, Transfer Functions, DOE, Tolerance analysis

Validate• Validate and verify solutions.

(Prototypes, Function Audits, Testing & validation)

Key features and advantages of DFSS over DMAIC..

DFSS methods – Focus on problem prevention/customer satisfaction (‘design quality in’)

Conventional Six Sigma Methods (DMAIC) – have focused on solving existing problems (‘find and fix’ continuous improvement).

Key features and advantages of DFSS over DMAIC..

Failure to understand requirements early results in increasingly expensive change costs later , especially in New Product development. DFSS Goal is to prevent late changes or identify them as early as possible.
