Samira Chen

Samira is Paul Stevens' designated backup for the vendor escalation management function — the most complex and highest-stakes of the seven critical functions in his coverage map. Her handling of a genuine vendor disputed invoice dispute during the second quarterly backup test — not a simulation, a real escalation, resolved in four hours without calling Paul — is the evidence that the cross-training model produces operational capability rather than theoretical coverage.

Her debrief after the first quarterly test — which produced two calls to Paul despite the unavailability protocol, because the SOP lacked the context for how Northgate classified subcontractors differently from primary vendors in dispute resolution — is the honest documentation of what testing reveals that documentation reviews do not.
