If you concentrate on the process using the results of the product verification you will gradually reduce rework until all output product is of consistent quality. It will therefore be possible to reduce dependence on product inspection and test. The requirements in element 4.9 are linked with other elements of the standard even when there is no cross reference. This relationship is illustrated in Figure 9.2. Planning production installation and servicing processes 4.9.1.1 The standard requires that the supplier identifies and plans the production installation and servicing processes which directly affect quality. The planning of production installation and servicing processes requires three levels Identifying which processes are required to produce install and service the product Designing commissioning and qualifying these processes for operational use Routing the product through the appropriate qualified processes In order to identify the production processes required to produce a particular product you need a production requirement in the form of product specifications which define the features and characteristics of the product that are to be achieved. By studying these specifications you will be able to identify the processes required to turn raw materials and bought-out components into a finished product. With manufactured products the processes may include machining welding fabrication assembly forming plating painting heat treatment etc. The next stage is to design the processes that have been identified. In many cases existing processes may well satisfy the need but process approval may be required if the tolerance on product characteristics is much less than the currently demonstrated process capability. Process design is a subject outside the scope of ISO 9001 but is covered by clause 4.2.4.9 of ISO TS 16949 and hence addressed in Part 2 Chapter 2. The plans that route an item through the various processes from raw .
