Quality Function Deployment (QFD)

Quality Function Deployment

Quality Function Deployment (QFD)is an approach to continual improvement that brings customers into the design of processestranslates what customer wants into what the organization producesoriginally developed in Japans Kobe Shipyard in the 1960sthe most widely used analogy for explaining how QFD is structured is a house

QFD Matrix StructureCustomer Input (requirements)Manufacturers current requirements/specifications to suppliers3. PLANNING MATRIXImportance RatingCompetition RatingTarget ValuesScale-Up NeededSales point

4. RelationshipsWhat do the customer requirements mean to the manufacturer?Where are the interactions among relationships?5. Prioritized List of Manufacturers Critical Process Requirements6. Identify trade-offs relating to the manufacturing requirement

QFD ProcessAt the first matrix, we put the voice of the customer, process it and have technical features as output.

For the second matrix, we use the out of the first, process it and produce the applied technologies to be used as output.Here is the list on the remaining QFD processes from the point of applied technologies up to specifications for the finished product:

Matrix 3-Input: applied technologies- output: Manufacturing ProcessesMatrix 4- Input: Manufacturing Processes-Output: Quality Control ProcessesMatrix 5- Input: Quality Control Processes- Output Statistical Control processesMatrix 6- Input: Statistical Control Processes- Output: specifications for the finished Product Benefits of QFDBenefits of QFD:1.Customer FocusedWe can be assured that the processes conceived will be based on the voice of the customers.2.Time efficientSince we know what the customers want, we can focus more on doing something about it an d not waste time on benchmarking or studying concepts or ideas that may be new in the industry but does not really address the needs of the customers.

3. Teamwork orientedDoing QFD alone is suicide. With a tremendous amount of information to cover that needs very accurate results in the shortest amount of time possible, working as a team is the most viable solution in implementing QFD.

4. Document orientedWith the matrices provided in the house of Quality, you have a record on what the clients want, what the company can do and how to compromise the two to meet customer satisfaction on the new product design.

12OTHER BENEFITS of QFD are:Shorter development cycleTrade-offs are made in the design, strategically, and not in the marker, tacticallyLower costs, increased productivityTeam commitment at the design stageCustomer Information: Feedback and Input

2 Broad Categories:Input -is obtained before the factFeedback -given after the fact.

QFD Tools1. Affinity Diagram used to promote creative thinkingUsed for creative thinking. It also organizes qualitative data gathered.2. Interrelationship Diagraphrecords the creative processEstablishes relationship between and among causes. 3. Tree Diagramshows the tasks that must be accomplished to solve the problemIt is the classification of tree of ideas in the affinity diagram4. Matrix Diagramused to identify connections among responsibilities, tasks, functions.it maps the voice of the customers against companies capabilities required to meet the customers needs.
