LEAN+: Quality Function

race - bikersLEAN+: QFD – Quality Function Deployment

Quality Function Deployment (QFD) is a management technique interwoven into the LEAN processes of Toyota Management System. It is “a product development tool that systematically deploys customer requirements into production requirements.”

As one of the key Total Quality Management (TQM) techniques, QFD relies heavily on the teamwork. Multidisciplinary teams are break the barriers of interdepartmental cooperation and improving communication, both internal and external.

QFD was used as a team-based technique to identify and translate customer requirements into technical specification used for product planning, design development, process planning and control and for production scheduling and monitoring purposes. QFD provides logical process of listening to what are true customer needs and expectations and, subsequently, determining how best to fulfill those needs. QFD’s overcomes successfully very typical problems: disregard of the voice of the customer, loss of information, and frequent differences between identified requirements. Quality Function Deployment takes broad product specifications or specific problems, and through a series of matrices, breaks them into specific action assignments. In short, QFD translates customer requirements into appropriate technical requirements.

The phases of QFD applicable to the product development cycle from product concept to actual production help to communicate (deploy) customer requirements to the design team and, ultimately, to the production operators. QFD is often associated with a paradigm shift from traditional manufacturing quality control to designed-in quality. This approach may be somewhat revolutionary for some companies but it can be easily justified as app.80% of overall project costs occur at the design development stage and only 20% are attributable to the other stages of product life cycle.

In the today competitive business environment QFD can play a key role in helping organizations to be stronger, more secure and, ultimately, more likely to win through:
– a systematic process focusing business on the customers
– proper identification of customer needs and expectations are identified and addressed
– customer requirements translated into meaningful engineering (or business) terms
– treating every unit down-stream as a “customer”, and every unit up-stream as a “supplier”(both internal or external to the company)
– better understanding of manufacturing/service processes and their interdependencies
– effective continuous improvements to the business processes and the designed-in and processed-in quality of products and services.

Examples of effective Quality Function Deployment are presented and discussed. Quexx training will familiarize you with Quality Function Deployment, and provide you with valuable guidelines “how to”:
– Set up research and continuously listen to what customers need
– Convert customer requirements into product specification and production requirements
– Deploy customer requirements throughout organization, including subcontractors
– Convert customer expectations into design features and product performance
– Define the interrelationships between critical characteristics, cascading in a logical flow, from the concept through the manufacturing to the post-manufacturing stages.
– Design a “house of quality”, where the “whats” (the customer needs and expectations) meet with “hows” (the engineering design features which satisfy “whats”) in the relationship matrix.
– Integrate the corporate Vision, Quality Policy and related goals with QFD.
