One of the most important tasks to avoid occurrence is certainly the clean documentation of components, batches, production processes, packaging processes and sterilization processes. Suppliers must be controlled and obliged to comply with testing processes (keyword: quality management agreement). For each product, every process is documented and archived, from supplier evaluation to individual testing. This also applies to product monitoring over the entire life cycle. If necessary, the customer must be able to trace all affected batches and inform users and distributors at short notice.
