MSO Customer Complaints enables the simple and traceable recording, processing and evaluation of customer complaints in accordance with the 8D method. Including definition and follow-up of immediate, corrective and preventive measures. The integrated 8D form can be saved directly from the application or sent directly to the customer, for example. Data such as article master, customer master, supplier master etc. can be imported and updated via interfaces. Complaints in MSO can also be automatically created and started for processing via interfaces with the recording of complaints in other systems. Evaluation options according to customers, products/articles, locations/areas, quantities and costs enable online analysis, for example with Pareto diagrams.
