The boardroom question is always the same: does Copilot pay for itself? After 12 months across five clients, the answer is yes — but not for the reasons Microsoft's case studies emphasize.
Where the time actually goes
The biggest gains aren't in document drafting. They're in meetings nobody attends anymore — recap-and-action emails that used to take 20 minutes happen in two. Multiply by every meeting in a 1,000-person company and you find your ROI quietly.
Where it fails
Anywhere your data is bad. Copilot is a magnifying glass for the quality of your SharePoint. Companies with neat document libraries got lift on day one. Companies with 15 years of unsorted attachments got hallucinations and rolled back. Fix your data first.
