Client Voices
What leaders say after the decision changes
Those programmes were still running because nobody wanted to be the one who ended them. Once we had to show they still earned their place, most of them did not.
We were going to build it ourselves because that was already the plan. They made us look at the other paths properly. The capital stayed in the business, and we launched two quarters earlier.
The room wanted the deal. They slowed us down long enough to name a price we would not cross. The acquisition did not proceed above it.
We were opening in places we already knew. They made us rank the pipeline again. Three projects came off, and the capital was placed where the return was stronger.
