Why Quality Function Deployment QFD is very important in a Six Sigma project?

Employing the QFD process and House of Quality matrices to each stage of product and service development process not only helps ensure that the final product or service meets the needs of customers, it can also help to identify waste.

How the Six Sigma is related to quality control?

Six Sigma is a method of removing defects from processes. Quality control is a continuous process that measures and controls the overall quality of products. One of the more popular quality control tools used in Six Sigma is known as DMAIC which stands for define, measure, analyze, improve, and control.

How Lean Sigma is related to Six Sigma?

Together, Lean aims to achieve continuous flow by tightening the linkages between process steps while Six Sigma focuses on reducing process variation (in all its forms) for the process steps thereby enabling a tightening of those linkages. Lean Six Sigma uses the DMAIC phases similar to that of Six Sigma.

What is QFD and how does it work?

Quality Function Deployment (QFD) is a structured approach to defining customer needs or requirements and translating them into specific plans to produce products to meet those needs. This understanding of the customer needs is then summarized in a product planning matrix or “house of quality”.

What is QFD used for?

QFD is used to translate customer requirements (or VOC) into measureable design targets and drive them from the assembly level down through the sub-assembly, component and production process levels. QFD methodology provides a defined set of matrices utilized to facilitate this progression.

Is lean and Six Sigma the same?

Lean is about eliminating wastes, taking time out of processes, and create better flow. From Improvement perspective, Six Sigma reduces variation and Lean reduces waste. Six Sigma aims at a process performance of 3.4 Defects per Million opportunity and Lean focuses on improving speed.
