In German companies the head of a department or project team assigns tasks to the team and to individual members, who carry them out ideally without any supervision. This logic is also at play in business relationships between customer and supplier.
When a German contracts a craftsman or mechanic – plumber, electrician, handyman – to do a job, he or she does not go beyond explaining the problem which needs to be solved. Everything else is left up to the person contracted to completed the job. The German customer expects the job to get done without any more input or oversight from them.
It‘s the same approach when one goes to the bank. The customer explains their financial situation, states their goals and then expects the financial advisor to do the rest, meaning come up with a financial plan. The bank employee, like the plumber, only contacts the customer if it is absolutely necessary.
