Reference #291: The First 90 Days
It is valuable to have a network of trusted advisors, both within and outside your organisation. To start, cultivate three types of advisers: technical advisors, cultural interpreters, and political counsellors.
Technical advisors provide expert analysis on technologies and strategy.
Cultural advisors help you understand and adapt to (or provide insight on how to change) a new culture.
Political counsellors help you deal with political relationships and help you implement the advice of your technical advisors
