## Full Content
M&A is often a vanity project for the board. The numbers look good on a spreadsheet, but the reality is 83% of UK deals fail to deliver projected synergies. This is not due to bad strategy. It is due to post-merger paralysis.

Integration planning is usually an afterthought. By the time the deal closes, cultural friction and operational silos have already destroyed the value. High-performing firms treat integration as a core competency. They automate the alignment of data and processes from day one. Anything less is just gambling with shareholder capital.
