Tip: You need a plan. Where to start?

Know your enemy

"So it is said that if you know your enemies and know yourself, you will fight without danger in battles. If you only know yourself, but not your opponent, you may win or may lose. If you know neither yourself nor your enemy, you will always endanger yourself."

Sun Tzu in "The art of War"

Start by trying to harness third-party, "Let's see what the new guy can do", anxiety and begin by looking for "Stategic alies".

So, put together a preliminary agenda with each and every manager and get down-to-earth answers to the following question:

0. "If you were me, what would you focus attention on?"

1. "What do you want to keep?" 

2. "What do you want to change?" 

3. "What do you want me to do?" 

4. "What are you afraid I'll do?" 

5. "What else do you want to ask me?"
