Seven HSI Red Flags
A one-page checklist for anyone responsible for a mission-critical capability programme. If you tick three or more, your programme has a human systems exposure that hasn’t been formally assessed.
Ungated and free to share. Built for capability development, programme management, and operational leadership.
The seven flags
Each flag marks a point where the human is being treated as a buffer for what the design failed to account for. The full checklist explains how to spot and act on each one.
Health Hazards
Noise, vibration or atmosphere flagged — and the response was administrative controls or PPE, not redesign.
System Safety & Survivability
The crew protection case covers external threats but not the internal environment people actually operate in.
Human Factors Engineering
The design was validated against a body that doesn’t match the actual, equipped operator.
Workforce & Personnel
The crewing model meets a minimum number but has never been validated against real operational tempo.
Training
Training is scoped for normal operations, not the edge conditions where the system actually fails.
Safety Culture
Expert concerns were raised — and not escalated.
HSI Programme Governance
An HSI plan exists, but no HSI authority with independent rights to escalate.
The Human Cost of Getting It Wrong
This checklist is the companion to our newsletter series on Human Systems Integration failures in major capability programmes — one failure domain per issue, anchored in the evidence.
