Give the IMO real authority, allow them to be a decision engine rather than just a reporting layer. Structure is also key, keep it lean, senior and embedded, the IMO should sit in the flow of execution, not above it. Action and Value, tracking and reporting are great but active tracking, action performing and value creating from reporting; if reports don’t trigger anything for the IMO he/she shouldn’t maybe be in that position. Lastly, culture is key they should promote accountability, encourage transparent reporting and reward teams for delivering synergies.
