A capability assessment is only as valuable as the decision it drives. Presenting it well to the board is what turns analysis into funded action.

The board doesn't want a spreadsheet. Open with the headline: where the business is strong, where it's exposed, and what you're asking for.
Dimension-level scores, methodology and evidence belong in an appendix, not the main flow. Keep the narrative to importance, gap and action.
Boards decide between options. Present the priority gaps as a small set of investment choices with clear trade-offs, and make your recommendation explicit.
The Business Capability Assessment Toolkit includes an executive report template and a board-ready deck built to tell exactly this story.
