The GUARDUS™MES Complaint Management module enables the efficient processing and follow-up of complaints and returns in one common system. Internal and external complaints are collected and monitored beyond the limits of a department or a location – from sales, quality assurance and production departments, and R & D to distant locations via Internet. This manages not only complaint reports, 8D-reports and findings (including failure images) for an incident but also commercial and technical decisions, as well as complaint costs, measures and deadlines. Thus, the customer always gets the latest status of his complaint. This quality knowhow offers concrete clues for product quality and is included together with the suppliers assessment in development and production planning.
