From narrative to comparability
Without a shared model, leaders compare teams using inconsistent language. Portfolio mapping adds a common frame for decision making.
The map should include both capability and risk dimensions so higher autonomy is not treated as universally better.
Keeping the model actionable
Refresh mappings on a fixed cadence and tie changes to concrete interventions such as governance upgrades or tooling changes.
When map updates stop influencing priorities, the model has become descriptive instead of operational and should be simplified.
