What does a single source of truth mean for company documentation?
A single source of truth (SSOT) means all company documentation lives in one authoritative location that everyone references. Instead of duplicate SOPs scattered across Google Docs, Slack messages, and email threads, there is one canonical version of each document. When something changes, it gets updated in one place, and everyone sees the current version.
Why do companies struggle to maintain a single source of truth?
The problem is rarely the initial setup. Teams pick Notion or Confluence, migrate documents, and feel organized for about three months. Then drift sets in:
- Someone creates a "quick" Google Doc instead of updating the wiki
- A process change gets announced in Slack but never reflected in the SOP
- Two departments document the same workflow differently
- Old versions linger in shared drives, and people follow the wrong one
The result is multiple competing versions of the same process, and nobody knows which one is current. New hires are especially vulnerable — they follow whatever document they find first.
How do you build and maintain an SSOT?
Building an SSOT requires both a platform decision and a cultural habit.
| Principle | Implementation |
|---|---|
| One platform | Pick one tool (Notion, Confluence, or a dedicated SOP tool) and commit to it |
| Clear ownership | Assign a process owner to each document who is responsible for updates |
| No duplicates | Link to documents instead of copying content into Slack or email |
| Review cadence | Schedule quarterly reviews to flag outdated content |
| Easy contribution | Lower the friction of updating — Glyde lets teams generate SOPs from screen recordings instead of writing from scratch |
The most important rule: when a process changes, the documentation gets updated before the change rolls out — not after, and not "when we get around to it."
