When to use it
Use it to expose missing decisions, conflicting mandates and handoff gaps.
When to be cautious
A populated matrix is not evidence that the people involved accept their roles.
Apply it
- List deliverables and decisions at a useful level of detail.
- Confirm who performs the work and who can accept or authorise it.
- Resolve conflicts directly and review the arrangement after changes.
An example in practice
A release has several contributors but nobody authorised to accept it. Resolve that gap before the deadline.
