One objective. Many frameworks. Honest gaps.
DTCF normalises what an organization must achieve into 3 objectives across 10 families, then maps each to the frameworks practitioners face. Mappings are graded: fully addressed, partially addressed, or deliberately absent with the reason recorded. An empty cell is a finding about the framework, not a gap in your programme.

How DTCF is governed
First edition. Objectives are normalised statements of what an organization must achieve. Mappings are graded: full, partial, or a recorded absence with the reason it is absent. An empty cell is a finding about the framework, not about the objective.
