Machine builder with fault codes and reference cards
A draft for a machine builder that runs its own service desk: a fault code can be typed in or picked from a row of common ones, and a reference card then states what it means, where the wording comes from, which checks the operator may run, and where the service takes over. Further sections list the stored documents, the cases in which the assistant deliberately stays silent, and the path of a report through to the entry in the service log. A toggle switches between the customer view and the technician view, and the report form checks machine number and fault code against a fixed pattern.
