Industry data suggests that 83% of mergers fail to produce the value promised to shareholders. This is the Synergy Trap. ![Synergy Failure Trend](https://static.prod-images.emergentagent.com/jobs/sched-2866d31f-92d1-431d-ac9f-1a8d77fdfd4c-1791187260038/images/dcdfcfd2b323b73f0e9f1f23385aedd6d99246c9b92489ec8dcac233d0fff969.jpeg) ## Integration is the Execution Gap Synergy failure occurs because integration is treated as a secondary task. In reality, the first 100 days post-close are the only days that matter for value capture. If you haven have not unified your GRC frameworks and PMO structures by day 90, you are already behind the curve. ![Synergy Capture Timeline](https://static.prod-images.emergentagent.com/jobs/sched-2866d31f-92d1-431d-ac9f-1a8d77fdfd4c-1791187260038/images/fc290ebb06512b17272b2dd9c92098f5b4786e414f77b95275950d26463e1524.jpeg) ## Value Erosion Metrics Deal value erodes quickly when decision latency sets in.
