Interim managers occupy insurance's most interesting consulting seat: you're not advising the decisions, you're making them – hiring, firing, signing, committing – inside someone else's company, usually through your own limited company, often in situations already distressed.
Before each engagement, answer three questions in writing: am I a director or officer here (and does the client's D&O name me); what does my PI cover of the decisions I'll take (not just advice I'll give); and will cover still be live when this engagement's claims mature? Interim work pays for decisiveness – insure the decisions, not just the advice.
