Start-up Management Tips
A good manager needs to spend more time with her/his team rather than his boss or peers. I have seen many middle managers working long hours behind closed doors to prepare weekly reports for their managers and cut themselves from day to day operations. These folks rely on high level and brief interactions with their directors. They do not spend time themselves to go through issues and picture the reality.
This can be a bigger problem in smaller companies. Because of the size and limited resources, you need to be more involved as a manager in day to day job. In start-ups you do not have the leverage of a highly structural organization. There is no clear vertical isolation between different functions and groups. Confusion is part of the game! But it is natural to solve the problem at the spot rather than pass it to other people. In a small organization you do not have that leverage.
