The most common stall is not a broken platform. It is a working platform that nobody was told what to stop doing. The weekly report still goes out as a re-exported attachment, review comments still land in chat, new drafts still start in the old tool, and the platform copy is politely ignored for six weeks. The platform is fine. The instruction was missing.
So write the stop list down and publish it with the end date.
- The report is the document. Not a PDF exported from it and mailed separately.
- Comments go on the document. Not in a chat thread quoting a paragraph.
- New drafts start in the workspace. Old ones are read-only; nobody needs to move them.
- Ask the champion when it is unclear. One route beats four opinions.
Announce the end date in week one rather than when you feel ready. Put the old tool into read-only before you revoke access, because read-only removes ambiguity first and revocation removes access second.
Exceptions exist, and they should be named rather than tolerated. A valid exception has an expiry and an owner: an external counterparty who will not move, a contract that specifies a format, a regulated record whose retention system is not the platform. “It is easier” is not an exception, it is the default coming back. Review the list monthly; unreviewed exceptions become the second system you were trying to retire.
The first four weeks, concretely:
- Week 1. Baseline the numbers, kick off with the first team using their own documents, publish the stop list, announce the end date, name the champion and the workspace owner.
- Week 2. Sit with people. Fix the two biggest friction points — usually search and the folder shape. Watch the five signals above and ask every Friday what could not be found.
- Week 3. If the signals are right, make the platform the default for the content classes the first team owns, and take the old tool read-only for those classes.
- Week 4. Measure created and co-edited documents, write down what broke, and choose the second team. The first team’s champion advises the second; the rollout owner does not run both.
If week four is flat, do not add a second team. Fix the first one. A stalled team multiplied by three is a stalled department, and by then nobody will believe the platform was ever going to work.
Sizing for the next wave is the one technical check that belongs in a self-hosted rollout plan: application nodes are estimated from user count rather than from editors, and the deployment documentation covers the formulas and the middleware baselines.
