Where are you now?
I am already in the role.
Make sense of your observations and review open questions.
Review your positionI am preparing my review.
Bring together feedback, evidence of impact and your follow-on plan.
Prepare your reviewWho this guide is for
For incoming managing directors, division and plant leaders, internal promotions and succession — especially where cultural, political or people-related alignment is demanding. Sponsors, HR partners and coaches can also use it as a shared framework for discussion.
An acute threat to the business or to safety requires stabilisation first. An unclear mandate must be resolved with the sponsor. This guide is not a covert performance assessment or a substitute for standard role-specific onboarding.
