A merger of equals approach to large-scale M&A “typically leads to confusion and reduces accountability, hindering integration,” McKinsey & Co. wrote back in 2011. The biggest difference between successful and unsuccessful deals is “the recognition in the former that one culture inevitably tends to dominate.”

The consultants had a point. M&A history is littered with equal partnerships that came unstuck because of clashing personalities and a lack of clear leadership. You don’t need to be a McKinsey partner to know that when you have “too many cooks” you might burn down the kitchen.
