Abstract

The invention relates to a process control method, in particular for controlling process qualification, process optimisation, quality assurance, delivery assurance and nonconformity prevention. According to said method, processes are represented in a data gathering module in an identified, organised and structured manner. A planning module for process control and monitoring is linked to the data gathering module. In said planning module, test equipment and/or measuring methods and/or classification methods are defined for product quality assurance and assurance of the production or service process. In a problem analysis and nonconformity recording module, problems and/or nonconformities are continuously structured, defined, recorded and evaluated. The problem analysis and nonconformity recording module allows preventive and corrective intervention procedures to be dynamically determined and implemented.
