Strategy and Tactics

What is the difference between strategy and tactics? In other words, where do you draw the line between what is strategic and what is tactical?

Effective leadership means  

You and your other German colleagues have a new boss, Susan Steel. Some of you know of Susan, a few have met her at company conferences, but none have worked directly with or for her. Next week Susan arrives in Germany as a long-term delegate and to begin her work.

Because she wants to quickly get oriented, Susan has invited each of her German direct reports for a one-to-one talk. She would like to understand the expectations of her as the team lead, but also communicate her views about the optimal working relationship between team lead and team members.

You’re in your home culture. In a similar situation. You want to help Susan to understand what makes for an optimal working relationship between a team lead and team members. Describe that relationship.
