Dependency and Common Mode Failure map
Show which workers share models, sources, policies, tools, identities, vendors, and people so one fault cannot spread unseen.
Under the pillar Operational Truth™, Risk, Liability, and Outcomes
Inputs
Worker roster, dependencies, integrations, shared policies, credentials, approvers, incidents, and outcome volumes.
Method
Map shared dependencies, fault types, detection, affected work, maximum cases before containment, authority reduction, and alternate paths.
Output
A concentration map with blast radius thresholds and drill cases.
Boundary
Case accuracy does not predict population harm from a shared fault.
Stop
Stop scaling when one untested dependency can affect more outcomes than the organization can detect, contain, and recover.
