There is no book that points out the right solutions in running a company. As a leader, you can create a system, but this must be run by people, some prone to errors.

So when problems appear in different areas all you can do is face it. Do not run away from it.

The more you face the problems, the more you become skilled in solving the problems.

Manage the situations the best that you can, and pray the everything you implemented and decided will go the way you expected it.
