    Strategic Product Family Development by Extending the House of Quality
    ( 2000)
    Hoffmann, J.

    Berger, S.
    Frequently, the market demands products provided with equal or similar functionality, that should be available for different customer groups. This market behaviour appears e.g. in the image processing field, where scanners, editing equipment, etc. are sold both to professional and amateur users. Because the product functions don't differ much from each other, or they are even the same, it is suitable to apply the same operating principles with variably, scaled specifications. However, the planning of such a product family occurs insufficient systematically in many companies and the products belonging to a determinate family grow without any co-ordination between themselves. The lack of delimitation of each single product and the non-using of synergy effects through model range design lead into loss of competition capability and market share. Initiated by this problem, a QFD-assisted instrument for defining a structured product family was developed. The benefit from using this instrument consists of an integrating view of all products belonging to a family on the one hand, and a strict customer orientation on the other hand. Moreover, this procedure offers the possibility of systematically defining and developing a complete product family corresponding to a company's objective, e.g. cost reduction, technology leadership or adaptation to a niche market. The instrument derives from the QFD-Quality plan and the House of Quality. Outstanding feature is the extension of the House of Quality by several specification classes as well as subsystems. It is possible, by the introduction of specification classes instead of the simple, classic target value, to analyse the specifications of different products within a family at a glance and define them in a coordinated, interactive way. The extension by subsystems offers beyond the possibility of defining the specifications corresponding to the company's objective. The developed instrument was proved on an exposer for the printing preliminary stage at a German company as an example.

    A QFD-orientated approach to improve relationships between marketing and product development. In business practice, repeated difficulties arise in communications between marketing and product development.As a result, products are frequently developed which do not correspond to the requirements of the market and possess significant weaknesses by comparison with competitive products. A QFD-orientated approach has proved successful in practice in avoiding communication problems.

    QFD - Aufwand, der sich rechnet

    The use of QFD for the development of software increases customer satisfaction. A challenge to systematic software development - three versions of programs for different customer segments should be prepared, involving the lowest possible development cost wihle achieving the utmost customer satisfaction. QFD, supplemented by a customer survey and a comparison with the competition, achieves this objective.

    The use of Quality Function Deployment (QFD) is becoming increasingly widespread in product planning and development also among small and medium-sized producers. Reference material is available in plenty about when to use which instrument. What is lacking is information on the conditions necessary to guarantee efficient, trouble-free use of QFD methods. This article seeks to close the information gap in this field by illustrating the example of a medium-sized enterprise.

    QFD-Einsatz in der Praxis

    Practical Application of QFD. Benefits also for small and medium-sized companies. Quality Function Deployment (QFD) has been used increasingly since the eighties in German-speaking countries. Small and medium-sized companies can also use QFD successfully in their product development. It is here, in particular, that the potential for the application of QFD methods opens up enormous scope. This article demonstrates benefits in practice and offers some ideas for improvement in the application of QFD.
