PPAP & Co – Quality management starts with development

It is always better to avoid errors than to correct them later. APQP, advanced product quality planning, follows exactly this principle. Its structured methods such as PPAP, the product part approval process as per ISO/TS 16949, and PPF, the german production process and product approval as per VDA Vol. 2, are designed to include all of the activities in the development and planning phase. They detect and eliminate sources of error in advance of series production. To do this, the product-relevant data must be determined, uniformly managed and centrally monitored. Parts suppliers need one thing in particular for this in-depth advanced quality planning: project managers that coordinate their activities with the customer's quality planning to the greatest extent possible.

Our advanced product quality planning takes hold long before series production.

In order to guarantee high quality products for end customers, a comprehensive quality management process including a long series of methods and activities is indispensable. Not only in series production, but long before as well. This is why the automotive industry has relied on an advanced product quality planning process for years: PPAP (PPF). The core idea is sampling series parts before the series start. Other sectors, for example the agricultural and construction vehicle sector, have jumped on the bandwagon. Our Technology team regularly deals with the relevant processes and documentation. Depending on the customer tasks and requirements, we are involved on various levels, from process failure mode and effects analysis (FMEA), the part submission warrant, the assessment of the visible parts with regard to their coating and the initial sample test report (german EMPB) to material test results, measurement reports from institutes and much more. We discuss the extent of our involvement with our customers and make a joint decision. Our customer AGCO Fendt, for example, receives a series of data and information on its bonnets directly from us in the PPA report. We also use PPAP measures for the exhaust pipe heat guard that we supply to Donaldson and for bonnet air grilles for JCB and Valtra.

Differences despite process standardisation

Although the process specifies a strictly uniform approach, each company can determine which parts of it satisfy their requirements and which do not. The key requirements are discussed in detail until the methods are used at the end of the development process. As a means of setting a basic quality framework for the collaboration, we also conclude a quality assurance agreement (QAA) with our partners. We have QAA with our suppliers as well, who we also subject to an audit. After all, each of the parties desires the same result: a flawless product.
