There isn’t any clear definition of management. This is something that evolved right from the time human beings existed. Only the way of managing things have changed. The human development was slow right from the medieval period to the 18th century. It really started picking up in the 20th century due to change in the management style.
From my past experience there are three tips I could give to be a part of a good management team.
1. Anyhow solve the puzzle, which could also mean getting from A to D without having to step into B and C.
2. If something needs to be done, just do it. Let others follow you rather than waiting for others to start
3. Think simple.
