Detection Coverage Maps Stakeholders Can Trust

Composite coverage scores invite questions unless everyone can see the journeys and events behind them. Publish the matrix: auth, privilege elevation, sensitive reads, admin actions—each with the events that should fire.

Keep the method stable for at least a quarter so comparisons stay fair. When you change scoring rules, call it out in the brief. Stakeholders forgive method updates; they do not forgive unexplained score drops.

Pair the matrix with one narrative paragraph. Numbers open the conversation; plain language closes it.

When product and security share one coverage map, gap funding stops being a vague request and becomes a sequenced plan.
