The 3-Space Decision Framework

The 3-Space Decision Framework

Where do I save this file? OneDrive, Teams, or SharePoint — the question everyone asks, and the one that causes the most mess when answered incorrectly.

The problem

  • Duplicate files scattered everywhere
  • No clear “official” version
  • Files saved with the wrong permissions
  • Teams not knowing where content lives

Most people guess. The 3-Space Decision Framework removes the guesswork.

The three spaces

OneDrive — Your personal workspace

  • Personal drafts and work in progress
  • Files not ready to share
  • Your own templates and notes
Key rule: If it’s yours and not official yet, it lives in OneDrive.

SharePoint — Your team’s knowledge hub

  • Official documents and templates
  • Content that needs structure and governance
  • Files shared across teams or departments
Key rule: If it’s team content that needs structure, it lives in SharePoint.

Teams — Active collaboration

  • Files being worked on right now
  • Meeting notes and agendas
  • Documents discussed in context
Key rule: If it’s active collaboration, it lives in Teams.

Use this decision every time

  1. Is this personal or shared?
  2. If shared, is it active collaboration or structured storage?
  3. Will its status change later?

Draft → collaborate → archive. Files should move as their purpose changes.

Quick reference

Scenario Where it lives Why
Personal draft OneDrive Not ready to share
Active team project Teams Collaboration in context
Official policy SharePoint Structured, long-term storage
Pro tip: Don’t be afraid to move files. One clean move beats ten duplicates.
