Performance is not meeting expectations.

Commitments are missed, results are inconsistent, or reported performance does not align with day-to-day operations.

Execution lacks consistency.

Meetings, scorecards, and initiatives have increased activity without creating clearer ownership or more reliable delivery.

Integration has not yet taken hold.

Following a transaction or significant change, teams, decisions, and ways of working have not fully come together.

A clearer basis for the next decision.
