DFSS: IDDOV

Question 1

IDDOV

Answer 1

How to Implement DFSS

IDDOV

• Identify
• Define
• Develop/Design
• Optimize
• Verify/Validate

Essentially, IDDOV includes more upfront work to establish customer requirements and translating them into the product design. IDDOV also includes the same elements of DESIGN and OPTIMIZE as found in DMADOV.

Question 2

IDENTIFY

Answer 2

IDDOV takes existing DEFINE phase and divides it into two modules with Identify and Define

IDENTIFY

• focusing on translating customer needs into the design of the product
• Project Charter

Question 3

DEFINE

Answer 3

IDDOV takes existing DEFINE phase and divides it into two modules with Identify and Define

DEFINE

• insures the product specifications meet the consumer’s needs.
• Customer’s needs and requirements

Question 4

Develop/Design

Answer 4

DESIGN – This is where 3D modeling or preliminary drawings occur. Once complete, the design is evaluated against tools such as FMEA and Design of Experiment (DOE) to insure all CTQ metrics are met. Other design tools include:

• QFD Matrix
• FMEA Failure Mode Effects Analysis
• TRIZ
• Brainstorming
• Pugh
• Taguchi Robust Design
• DFX – Design for X

Question 5

Optimize

Answer 5

• Parameter design

- Tolerance design

Question 6

Verify/Validate

Answer 6

This is where validation testing of the design occurs. Pilot runs are employed to validate design success. After the product or process is validated, a plan for full implementation, allowing metrics to continue to monitor gains. Detailed process maps, work instructions, flow charts, and checklists are created to ensure a fool-proof transition to the operations team.

Finally, the DFSS Team is closed and team members take on new projects.
