German service is expected to be thorough — complete rather than partial, proper rather than approximate, detailed rather than superficial. When a German professional handles a service task, the expectation is that they will do it fully, leaving no loose ends, cutting no corners, and attending to details that less thorough approaches might skip. This thoroughness is valued because it produces results that hold. A problem solved thoroughly stays solved.
A service delivered thoroughly needs no follow-up to fill gaps. When serving German clients, invest the time to do things properly.
If something needs to be investigated, investigate it fully. If a report needs to be prepared, prepare it completely. Thoroughness may require more time upfront, but Germans understand this tradeoff and respect it.
