Quality Function Deployment for Competitive Advantage

The relationships are recorded in the relationship L-matrix and the interactions recorded in the Roof-matrix. Additional details on competitor and technical details are optional and can be added as desired. The software then automatically creates the ranks and importance of each factor. You can also weight the individual performance characteristics if a distinction needs to be made between the characteristics. Now, you must examine how the product performs for each requirement. For example, if customers want a faster electrical object, you must take a closer look at the motor.

First, it allows you to get a clearer idea of how the product or service should be positioned in the future. It also helps you to prepare for the next step, where you will look more closely at the target group.

It starts with the Voice of the Customer which becomes the basis for setting requirements. From that, the organization identifies the what’s – the most important needs of the VOC. From there, a team will identify the how’s– those areas of process focus that address each of these identified requirements. The roof of the house shows the correlation between the technical specifications.

Technical evaluation (on a one to five scale)

This is consistent with the quality function deployment approach found in leading Japanese companies. Placing the customer first and constantly circling back to a customer focus during the design phase is the cornerstone of QFD. The Quality Function Deployment process begins with collecting input from customers , typically through surveys. The sample size for these surveys should be fairly significant because quantifiable data will carry more weight and avoid letting any outlier comments drive product strategy in the wrong direction. You can now enter all the information collected in the QFD matrix and build ahouse of quality.

As a cost savvy project manager, equally important is the PMP Salary hike expected or what is my ROI- Return on Investment. You can understand the PMP salary increase, the cost involved, benefits both tangible and intangible from PMP Certification. These include higher levels of innovation and rewarding product design jobs. The initial part of the quality function deployment framework involves collecting feedback from the ultimate consumers of the product. This is achieved in a number of traditional ways through questionnaires, surveys, market research, etc.

The Level 3 QFD is used during the Process Development Phase where we examine which of the processes or process steps have any correlation to meeting the component or part specifications. In the Level 3 QFD matrix, the “Whats” are the component part technical specifications and the “Hows” are the manufacturing processes or process steps involved in producing the part. The matrix highlights which of the processes or process steps have the most impact on meeting the part specifications. This information allows the production and quality teams to focus on the Critical to Quality processes, which flow down into the Level 4 QFD for further examination. It conducted the quality function deployment to review the customer requirements, technical attributes, target values, competitiveness and measures for enhancing the product and process quality. The house of quality, a part of QFD, is the basic design tool of quality function deployment.

The tunnel vision focus of QFD on the customer can also have some negative repercussions if customer needs drive up product costs or delay technological innovations that could benefit the company down the line. After completing the surveys and aggregating the data , it’s boiled down into the Voice of the Customer. These customer requirements, requests, demands, and preferences are framed as specific items and ideally ranked in importance. These are then listed on the left-hand side of the House of Quality matrix and represent what customers want the product to do. At the end of the Quality Function Deployment process, a clear catalog of measures will be produced.

What could benefit Roy’s business is quality function deployment , which is a way of understanding what your customers want and need and then creating products to meet those wants and needs.

The diagram shown here will also help you understand the QFD methodology here.

Fourth House of Quality – House 4, the process control house, is typically constructed during the control phase.

In the customer house, the primary goal is to translate the voice of the customer into unambiguous and clear language. A business must understand what measurements the customer is using to determine if it has met their requirements. Next, the company must identify it’s internal metrics which determine if it has met the customer requirements.

These are critical requirements in combat conditions, so that the protective garment does not hamper the soldier’s performance. The durability of the GTWM is represented in terms of a wear life of 120 combat days and its ability to withstand repeated flexure and abrasion – both of which are characteristic of combat conditions.

  • At the bottom of the matrix, the column is summed, which allows for the system characteristics to be weighted according to the stakeholder characteristics.
  • Often, customers themselves are not sure exactly what they expect from a product.

Level 4 QFD

A structured approach and set of tools used to define customer requirements and convert them into detailed specifications and plans to produce the products and services which fulfill those requirements. Quality function deployment helps to reduce the length of product development cycles, leading to lower start-up costs. It also offers a systematic method of gathering information and cultivates a more collaboration-focused working environment.

Phases two and three develop specific components of your service and specific process requirements to deliver your service. Phase four will develop your quality control processes to be sure you’re delivering your service with high quality. Cascading down from the HOQ, they engaged their construction, facilities and IT departments to help with QFD phases 3 and 4.

At this stage, the product’s quality control throughout the production process is determined. House of quality is a matrix which is the basis of product planning, and its diagram looks like a house. An application of the QFD method to the design of a hand-held hairdryer product is explored here. As there are many hair dryers in the market, the aim is to provide a quality solution that has added attributes in comparison to the many ‘me-too’ competing products. •The importance of the customer requirements is specified in the column after the customer requirements.

The house of quality’s roof is formed by the relationships between the different product characteristics. The concept provides a tool for the business for maintaining their focus on the consumer. As a framework or concept, rather than a process, the business can refer back to it at all stages of the product development process. The development of the product remains sensitive to the dictates of the market through robust alignment to the needs of the consumer. Although it might sound like a modern testing methodology, Quality Function Deployment has a 50-year track record of putting customer needs first throughout the entire product development process. The customer requirements are simply fed into the rows and the design requirements fed into the columns.
