Unlike fatigue consultancies that apply standardised shift-pattern scoring, OHP models fatigue against the specific physical and cognitive demand of the role, drawing on occupational physiology research to identify where a roster design creates risk that generic fatigue software would miss.
The gap in generic roster-fatigue scoring
Most commercial fatigue tools score a roster on hours worked, time between shifts, and circadian position, useful, but blind to what the crew is actually doing during those hours. A twelve-hour night shift monitoring a control room and a twelve-hour night shift on active emergency response carry very different fatigue loads even at identical roster parameters. OHP's assessment layers physiological and cognitive demand data over the standard roster metrics, so the fatigue risk picture reflects the actual work, not just the shift pattern on paper.
This matters most for frontline teams where the work itself varies shift to shift, emergency services crews, aviation ground and flight operations, defence rostered watches, resources-sector shift teams, because a fixed roster template can look compliant on a fatigue calculator while still under-controlling risk on the shifts that matter.
What the engagement produces
Working through The Crucible Method, OHP's rostered-team FRM engagements produce:
- A fatigue risk assessment specific to the roster pattern and role demand, not a generic industry benchmark
- Practical roster design guidance, informed by what the team is realistically able to change given staffing and operational constraints
- Control measures for the highest-risk shift types identified in the Scan phase
- A governance and reassessment structure so the framework holds as staffing or rostering changes over time
Anthony Walker's PhD research in thermal and occupational physiology, combined with 15 years of operational command experience with ACT Fire and Rescue, underpins how OHP reads fatigue risk in rostered frontline environments. The assessment isn't built from desk-based fatigue theory; it's built from direct knowledge of what a rostered frontline shift actually demands physically and cognitively.
Frequently asked questions
What makes a fatigue risk framework suitable for rostered frontline teams specifically?
It needs to account for variable operational demand within the roster, not just the roster pattern itself. A framework built on hours-and-circadian scoring alone will under-control risk on high-demand shifts and over-control on low-demand ones.
Does this apply to teams with irregular or on-call rostering, not just fixed shift patterns?
Yes. Irregular and on-call rostering typically carries higher fatigue risk than fixed shift patterns because recovery time is less predictable. OHP's assessment approach is built to handle variable and on-call rostering.
How is this different from a generic fatigue management policy?
A policy document sets rules; a Fatigue Risk Management System is an operating framework with assessment tools, roster design principles, and a review cycle behind it. OHP builds the system, not just the policy document sitting on top of it.
