Coverage
How AppThentic shows which parts of your business are understood, and which are not.
AppThentic does not claim to know your whole business. It shows coverage: how much of each area has an owner, an approved reason, and current evidence.
What coverage shows
For each area (a service, a domain, a team):
- Rules found, and how many are Approved, Inferred, Disputed, Stale or Unknown.
- Rules with a single knowledgeable person: the places where one departure would leave nobody able to explain.
- Rules nobody owns.
- Rules changed since approval.
Why it matters
A sample is not the whole. If 15 of 50 services have approved rules, AppThentic says 15 of 50, not “understood”. Leaders see exactly where the risk sits instead of trusting a summary.
Research on open-source projects found that 46% of popular GitHub projects depend on a single developer for most of their knowledge, and 28% on just two (Avelino et al., 2016). Most companies have never measured the same thing in their own systems. Coverage is how you measure it.
Using coverage
- Plan where AppThentic asks next: high-change areas with low coverage first.
- Plan offboarding: rules that only a leaving person can explain. See When someone leaves.
- Report honestly to auditors and leadership. See Audit and compliance.
