Quality Function Deployment. Sometimes referred to as the House of Quahty, quahty function deployment (QFD) is a technique for translating the voice of the customer iato design requirements (19). This is a systematic approach identifyiag customer expectations and relating the expectations to product properties. The usage of QFD ia the chemical iadustry appears to be growing. QFD results ia chemical specifications optimized to assure the material is suitable for its iatended use and performs up to customer expectations.

The spiral shows actions necessary before a product or service can be introduced to the market. Each specialized department in the spiral (e.g., customer service, marketing, purchasing) is given the responsibility to cany out its assigned special function. In addition, each specialized department is also assigned a share of the responsibility of carrying out certain company-wide functions such as human relations, finance, and quality. Quality results from the intenelationship of all departments within the spiral. Juran talked about the quality function to describe activities through which the departments around the spiral can attain quality.

Juran [4] defined QA as the activity of providing to all concerned the evidence needed to establish confidence that the quality function is being performed adequately. The definition of PV is that it is the total activity, showing that the process will do what it is purported to do. The relationship of QA and PV goes well beyond the responsibility of any QA function nevertheless, it is fair to say that PV is a QA tool because it establishes a quality standard for a specific process. 

The QA that exists within an organization rests not only on the management of the quality function but also on the activities that occur on a daily basis in the company s technical and operational functions. These groups are responsible for the training of the personnel to achieve a company culture based on quality. They develop and carry out the procedures that govern the product composition, the manufacturing process, the test criteria, or the operating system, which ensures that the quality function is performed adequately. 

Equipment calibration. This quality function for production consists of a viable calibration program for equipment that provides in-process test data or a measurable indication of the controlled process used. This activity is needed so that the manufacturing unit will know whether the equipment is operating consistendy during the time period covered by the calibration activity. This effort is also a continuing commitment of production to maintain its equipment as it was documented to perform during its installation qualification (IQ) and operational qualification (OQ) activities. 

These examples show how quality standards are established in production and how quality improvements may be sought. When PV is used as a QA tool, these quality standards enhance the potential for maintaining a validated process during routine production. They then will be the basis for QA confidence [4] that the quality function is being adequately performed in production. 

Quality assurance functions primarily to monitor the fact that the quality function is being performed. Its role in PV is readily associated with its main functions. For example, it performs the tests that demonstrate the product s content uniformity. It may also perform the statistical evaluation of the test results to show that the process is reproducible. Quality assurance initiates the action to dispose of nonconforming product. It implements the inspection criteria and sets the specifications for product approval or rejection. It analyzes the product complaints to learn how effective its test program has been in preventing reject-able product from reaching the marketplace.
