Design for Six Sigma (DFSS) uses several tools.
Match the name of each tool to the corresponding description.
Ans: DOE - helps determine the effects of inputs (factors) on outputs (responses)
FMEA - is used to analyze how failures may influence design parameters
Robust design optimization - results in an optimal design that is immune to various types of
failures
QFD - helps translate customer needs into technical requirements
Which of these situations call for a DFSS strategy?
Ans: - a cell phone company has designed a new phone to meet..
- a university has implemented a range of six sigma projects..
- a travel agency is upgrading its booking software and ..
There are specific activities to perform and questions to ask at each stage of the DMADV
methodology.
Match each stage of DMADV with the corresponding question to ask at that stage.
Ans: Define - what are the project's goals?
Measure - what are the specifications for the product?
Analyze - which of the design options will best meet customer needs?
Design - does the product achieve customer levels, or does it need to be reworked?
Verify - does the final design performance have the ability to meet customer needs?
Match the methodology with its corresponding characteristics.

, Ans: DMADV - completely redesigns a process or product
DMAIC - improves on existing product or process , the final outcomes do not rquire
verification
IDOV - creates a new process. a DFSS methofolgy modified by General Electric
What are some characteristics of FMEA?
Ans: - it's used to understand the impact of failures on customers
- it helps you identify and prioritize potential problems based on their overall impact
- it helps identify corrective action to address serious potential problems
One of the methodologies employed in DFSS is IDOV, which stands for Identify, Design,
Optimize, and Verify.
Match each stage in the IDOV methodology with its corresponding activities.
Ans: Identify - gather voice of the customer information and ide..
Design - generate a concept design and analyze and test it
Optimize - create prototype based on the intial concepts
Verify - test and confirm the quality control systems using..
Which of these situations favor a DFSS deployment?
Ans: - a tire manufacturing facility..
- process improvement teams..
- a hospital has implemented..
Label characteristics as belonging to either DMAIC, DMADV, or IDOV.
Ans: DMADV - used to create new six sigma compliant processes.. , used when redesigning
an existing product..
IDOV - the goal is to create a new product.. , one of the stages is identify
DMAIC - aims to improve.. , you assume that the existing process can be improved..
