What is Quality Function Deployment (QFD) in Six Sigma?

In Six Sigma quality improvement, the voice of the customer (VOC) is crucial. The customer determines value and quality. Thus, a business that views itself through its customers’ eyes and evaluates itself the way they do has a crucial edge in enhancing quality.

In today’s competitive business world, quality is crucial. It helps a business find its specialty. Therefore, Quality Function Deployment (QFD) across all verticals has become a business’s top priority.

Simply put, QFD is the “Voice of the Customer,” agreeing to the “Voice of the Designer.”

Quality Function Deployment – Overview

Quality function deployment is a LEAN approach that Six Sigma Black Belts can employ. It’s an excellent tool for designing processes or products to meet consumer needs. The online free Six Sigma course briefly explains that it fits within the Define phase of the DMAIC structure. It’s one of many LEAN tools covered in Lean Six Sigma Green Belt training. Let’s know more about quality function deployment!

What Exactly does “Quality Function Deployment” Mean?

Three words make up the term:

  • As for quality, it’s all about meeting the customers’ demands.
  • As for function, it’s all about concentrating on the work that you must complete.
  • In terms of deployment, the key questions are who will do what and when.

QFD is about taking consumer feedback and using a well-structured, well-established strategy or procedure to turn it into the specific technical requirements needed at each step of product development and manufacturing.

Dates Back to its Evolution

In 1972, Yoji Akao and Shigeru Mizuno utilized the technique to design an oil tanker at Kobe shipyards in Japan. Before this, quality control focused on resolving problems during or after manufacturing. Don Clausing of MIT introduced this tool to the US in the mid-1980s.

The four cascading matrices or Houses of QFD are:

1) Product planning matrix: Collecting VOC and translating client needs and desires into products and specifications is the first process. It also incorporates a competitive analysis to assess your competitors’ customer satisfaction. The basic design concept is based on specific product and service performance needs and specifications. The QFD process begins with the House of Quality.

2) Part Deployment Matrix: This phase identifies the assemblies, systems, sub-systems, and components that have the most impact on satisfying your product and service design criteria. Critical product and service qualities cascade down and transform into essential parts, assembly characteristics, specifications, and service process steps. For each functional area, these standards or specifications are defined.

3) Product and Service Planning Matrix: This phase designs production and assembly methods based on your product and component specifications. You’ve covered customer, product, and process requirements.

4) Process and Quality Control Matrix: You can test your goods. After identifying product characteristics, you’ll want to ensure a good strategy and product quality controls. During the pilot run, you can verify these. Before starting full production, the process must be in control.

Six Sigma concept

Many companies use Six Sigma to improve process/product quality and boost customer satisfaction and revenue. It involves hands-on application in all industrial processes.

Three porticos define Six Sigma:

1) Minimize variation to make processes predictable and reliable.

2) Characteristics of inputs cause process variances in manufacturing and service businesses. Measure, evaluate, control, and enhance these.

3) Like every other method, six Sigma works through sustaining results. It requires organization-wide commitment and top-management support.

How to Get in-depth Knowledge About QFD?

QFD, the House of Quality, and Six Sigma are used in many businesses today.

Join this Quality Function Deployment certification program in India to learn how to use tools to build customer-focused goods.

Lean six sigma green belt certification course teaches participants how to develop resilient products and services, document design process methods, and create and control maintenance strategies.

You’ll learn the theory, composition, and execution of Six Sigma by finishing this course. Using analytical tools, you’ll also learn how to define, measure, evaluate, improve, and control Six Sigma improvement programs. They will teach team leadership and project management. In summary, you will learn how to lead a difficult process improvement project that yields bottom-line outcomes.

Suppose you enroll in a certification version of this course. In that case, you will receive a Lean Six Sigma Green Belt certificate and a Six Sigma improvement project after completing the course.

Why take Lean Six Sigma Green belt certification?

Lean Six Sigma Green belt certification covers all about D-M-A-I-C. They can employ Six Sigma and Lean principles. Lean Six Sigma Green belt (CLSSGB) courses teach Lean Six Sigma concepts and terminology and prepare you for the CLSSGBTM Exam.

You will learn to lead Lean Six Sigma process improvement projects, work with Black Belt-led teams, and help your firm implement Lean Six Sigma.

Persistence, knowledge, and dedication match Six Sigma project performance. Most stakeholders consider the champion and Black Belt roles before deploying the project.

Green Belts will also increase process quality and project performance. Green belts improve process quality as team players.

Lean Six Sigma Green belt applicants enhance the process, data inspection, and project management. Green Belt training covers project team tools, DMAIC, and QFD for Six Sigma projects.

Training covers:

  • Introduction, history, and uses
  • House of Quality (HoQ) structure
  • The systematic transition from customer needs to process parameters
  • QFD matrix cascading examples
  • Design Scorecards as control instruments: linking QFD and design scorecards at various levels

Concluding words

You can come closer to the “ideal” product by controlling key process variables. You can trust your product’s quality using Six Sigma. It is especially critical when a company’s public image is vital to consumers.

You can apply the QFD approach and the House of Quality matrices at any point in the product or service development cycle to understand better and address customer needs and uncover areas of inefficiency. You might cut non-value-added activities from a company if its capabilities do not meet client needs.

Lean Six Sigma Green belt certification from Simplilearn online courses will boost your profession! Their Lean Six Sigma Green belt certification online curriculum, aligned with the IASSC test, teaches DMAIC methodology and real-world case studies to help your firm thrive.
