C.      Design for Six Sigma (DFSS) in the organization

                                                       1.            Quality function deployment (QFD)
Describe how QFD fits into the overall DFSS process. (Understand) (Note: the application of QFD is covered in II.A.6.)

                                                       2.            Design and process failure mode and effects analysis (DFMEA & PFMEA)
Define and distinguish between design FMEA (DFMEA) and process (PFMEA) and interpret associated data. (Analyze) (Note: the application of FMEA is covered in II.D.2.)

                                                       3.            Road maps for DFSS
Describe and distinguish between DMADV (define, measure, analyze, design, verify) and IDOV (identify, design, optimize, verify), identify how they relate to DMAIC and how they help close the loop on improving the end product/process during the design (DFSS) phase. (Understand)

Design for Six Sigma (DFSS) is the suggested method to bring order to product design. While DMAIC is the six sigma process that defines an existing problem within an existing process, IDOV ((identify, design, optimize, verify) is a data-driven quality strategy for designing new products and processes.

Quality Function Deployment (QFD) - is a structured methodology and mathematical tool used to identify and quantify customers' requirements and translate them into key critical parameters. This method is sometimes referred to as the “Voice of the Customer” (VOC). The House of Quality (HOQ) is the first matrix in a four-phase QFD (Quality Function Deployment) process. It's called the House of Quality because of the correlation matrix that is roof shaped and sits on top of the main body of the matrix. The correlation matrix evaluates how the defined product specifications optimize or sub-optimize each other.

Design Failure Mode And Effect Analysis (DFMEA), and Process Failure Modes Effects Analysis (PFMEA) are tools used to: (a) recognize and evaluate the potential failure of a design or process and its effect, (b) identify actions which could eliminate or reduce the occurrence, (c) document the design or process, and (d) track changes to the design or process to avoid potential failures. The DFMEA focuses on failure modes caused by design and PFMEA focuses on process issues. The PFMEA should not rely on design changes to correct process weaknesses.
