What is Quality Function Deployment?
Although it might sound like a modern testing methodology, Quality Function Deployment (QFD) has a 50-year track record of putting customer needs first throughout the entire product development process. Focusing consistently on customer desires, QFD ensures these are always considered during both the design process and various quality assurance milestones throughout the entire product lifecycle.
What are the Advantages and Disadvantages of Quality Function Deployment?
Quality Function Deployment benefits companies primarily by ensuring they bring products to market that customers actually want, thanks to listening to customer preferences at the beginning of the design process. Then, mandating these needs and desires is met throughout every aspect of the design and development process. In short, if something isn’t being built because a customer wants it (or it provides underlying support for a customer need), it doesn’t get built at all, which can prevent technology from driving strategy when it’s not directly beneficial to the customer experience.
How did QFD impact the design process?
Once adopted, QFD shortened design cycles significantly and reduced the total number of employees required in the design process. Shifting the focus from bottom-line cost analysis to customer satisfaction brought innovations and increased sales of domestic vehicles after the surge in popularity of Japanese imports in the 1970s.
Why is customer input important in product development?
Since collecting customer inputs and applying them throughout the product development process is such a cross-functional activity, it can also increase teamwork and ensure the entire organization is aligned around customer satisfaction instead of competing with other internal priorities.
When was QFD introduced?
Developed in 1960s Japan, QFD was imported to the United States in the early 1980s and caught on thanks to its popularity and successful track record in the automotive industry. Copying the model from manufacturers such as Toyota and Mitsubishi, the “big three” American car makers used QFD to bring customer centricity to their industry.
When is QFD appropriate?
QFD is most appropriate when companies are focused on relatively iterative innovation versus something completely new since there is a large base of customer feedback and input to drive the process. When a product is creating a completely new category, it’s more difficult to fully articulate the voice of the customer since they don’t necessarily have a frame of reference, but even in these cases carrying forward what is known about customer needs and preferences can provide value.
When to use QFD?
It is most effective when used throughout the entire product lifecycle, as its main purpose is to ensure a constant focus on the voice of the customer. You can’t “check it off” as completed since it is an ever-present ingredient every step of the way.

Mitsubishi and Toyota, as well as many other companies, have used this method to better tailor their products and services to their target market and accelerate growth. As part of this method, customer requirements, product performance, and the products offered by the competition are all taken into consideration.
What are the advantages of QFD?
Another advantage of Quality Function Deployment – when implemented early and effectively – is that it can reduce development costs and times. As this method focuses on customer requirements with a well-thought-out method and is not based on assumptions, you can use it to make specific plans. Not only does QFD support companies by helping them to increase their revenue, but it also helps them to work in a more streamlined manner during production.
What to ask yourself during product development?
The first thing to ask yourself during the product development phase is who the product is aimed at or who will buy it later. You must also think about the distinction between B2B and B2C – a relatively banal subject. Next, you must consider information such as income, gender, marital status, age, and level of education. Finally, you may have to make some assumptions about details that are more difficult to measure, such as the requirements, standards, and values of potential customers.
Is quality function deployment a fixed model?
Quality Function Deployment is not a rigid, fixed model. It has undergone many further developments since it was first used by Yōji Akao (e.g. such as those implemented by Bob Kind or Emil Jovanov). Even Akao himself believed that it was incredibly important for each person to adapt the concept to their own situation. Something that all variants of the method have in common is that they proceed step by step, starting with a customer survey and finishing with production or the product launch.

Part Deployment Matrix: During this phase, the assemblies, systems, sub-systems, and components that have the most impact on meeting your product and service design requirements are identified. The critical product and service characteristics cascade down and are translated into critical parts and assembly characteristics or specifications as well as steps of a service process. These requirements or specifications are then defined for each relevant functional area.
