We don't manage companies or departments.
We manage people in companies and departments.
It's people skills and managing them.
We don't manage a project, we manage our interactions and relations with people who implement a project.
We don't manage a stage, we manage the people who follow and implement a system for running a stage show.
If that's the case, how come we don't teach people skills and be people oriented. If communicating with people takes up 60-80% of our time why aren't those skills taught? Why leave it to chance interaction or whether you were fortunate enough to be born with good parents or friends?
