McK's back office practice has really grown over the past decade with (imo) little to show for it. Their whole QuantumBlack offering is utter bullshit, and they had a couple other back office boondoggles.
Also, doesn't help that companies don't hire Management Consultants as much anymore AND implementation firms like Accenture, WITCH, Deloitte, and EY have climbed up the value chain to offer bundled Management Consulting and Implementation, which McK only really started offering like 5-6 years ago.
On the other hand, f** Partners, having too make do with $700k instead of $1.4m:
"Under a plan dubbed Project Magnolia, the management team is hoping the move will help preserve the compensation pool for its partners, the people said, asking not to be identified discussing non-public information."
