Often German managers would rather complete a certain task themselves instead of passing it on to a team member. Many do repairs in their house, fix their cars, and some sit in their office at home until late into the night.
For those with limited financial resources, doing things yourself might be a question of economics. For others, there is a German reason: they often have a clear picture in their mind of how the final product should look. That they don‘t hand it off to a team member is not a sign of mistrust or lack of confidence.
Instead, Germans are skeptical that the other person will fully understand what is expected. By the time they have explained the task and how the final outcome should look, they most likely will have completed half of the work.
For the team member will create her own picture of the final product. Two pictures of what the work should look like. A dilemma for every customer-supplier relationship.
