COURSE GOALS:

- Understand what DFSS is all about and how it differs from traditional Six Sigma

- To understand and apply Six Sigma/DFSS tools and concepts for the purpose of gaining knowledge and improving the bottom line.

- Be able to construct a DFSS Scorecard to predict yield and identify problem areas for resource allocation and attention

- Become familiar with methods for identifying the voice of the customer and understand how to construct a House of Quality

- Understand methods for evaluating risk including failure mode and effect analysis (FMEA)

- Be able to complete a Pugh analysis to select the best concept or help narrow the focus

- Understand the use and importance of transfer functions in DFSS and methods for generating them

- Be able to complete an expected value analysis (EVA) for predicting product performance using transfer functions

- Understand how to apply robust design analysis for reducing variation and minimizing sensitivity to noise

- Be able to complete  a tolerance allocation analysis to understand the impact of design variables on performance

- Understand the importance and role of designing for manufacturability and other key aspects (DFX) in addition to designing for performance (DFP)

- Understand the importance of testing and validating prediction models and strategies for gap analysis when results do not match

- Practice applying the DFSS IDOV process using an in-class design exercise
