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.

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 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.
What is the purpose of QFD?
The main aim of QFD is to improve a product or service so that it will be better received by the market. The focus here is also on customer satisfaction.

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).
