Permissions And Ownership
Permissions decide who can access content. Ownership decides who is responsible for it.
Why It Matters
Microsoft 365 problems often look like permission problems, but the real issue is unclear ownership. If nobody owns a Team, site, library, or template, nobody can confidently decide who should have access.
Minimum Ownership Pattern
For every important workspace, define the business owner, technical owner, intended audience, and review rhythm.
Keep It Understandable
Prefer groups over individual permissions. Use clear names. Avoid unique permissions unless there is a real reason.
Simple permission models are easier to support and safer to maintain.
