Advanced Product Quality Planning accompanies the development of a product and is intended to ensure that all of the customer's requirements are met. The objective is to provide a quality product at the right time.

In order for the development activities to be carried out, it is necessary to define the targets for the project and the communication channels between the parties involved (customer, supplier, subcontractors). To ensure constant coordination and continuous monitoring of the project, milestones are agreed. These milestones require the completion of specific activities. At these milestones the degree of compliance, or rather the status of these objectives, is checked. In principle, the specified dates must be met.

If the status is assessed positively, subsequent activities are released. In the event of non­compliance, preventive and corrective measures must be implemented by the supplier at their responsibility. These must then be monitored and a further course of action agreed upon. This should ensure that all activities are completed on schedule and that any necessary modifications are recognized at an early stage and late changes avoided.
