When you get into the office, do you reflect upon your own performance and how it affects your team? Both managers and coaches may do this, but their considerations will differ.
The manager will think in terms of short-term efficiency and productivity, in short having a well-managed office and team. The coach, however, will be thinking about developing his or her leadership skills so as to better coach his or her team members to long-term success.
In business, managers think in terms of the day-to-day operations, whereas coaches, while mindful of those, also think in terms of the season and beyond. Coaches want more than won games; they want winning players.
