Real-time Fatigue Risk Assessment
Fatiguefit4Duty
Structured assessment at the point of duty, combining the sleep a person actually got in the last 24 and 48 hours with how alert they feel now.
The problem
A compliant roster can still put a fatigued crew to work
The operational predictor of fatigue impairment is prior sleep and wake history, not hours on duty. Hours-of-service rules cannot see the night someone spent with a sick child or the sleep disorder nobody has diagnosed.
Fatiguefit4Duty asks, at the start of duty, the questions that do predict impairment, and puts the answer in front of the person who has to make the call.
How it works
How it works
- 01
Prompt
A supervisor prompts the assessment at the start of duty. Around thirty seconds, on a phone, and it works offline.
- 02
Sleep and alertness
Prior sleep in the last 24 and 48 hours, time awake, and current sleepiness on the Karolinska Sleepiness Scale.
- 03
Risk indication
Likelihood from prior sleep and wake history, combined with a consequence rating assigned by role, in an ISO 31000 calculation.
- 04
Shown to the leader
The result goes to the team leader or safety manager, with the role- and task-based controls you have configured. The decision stays with you.
What the client sees
Who sees what
Unlike Sleepfit, this result is not private to the worker: it exists to inform a control decision at the start of duty. Band thresholds and their derivation are published to you.
Priced on prevalence, not headcount. How pricing works.
- Who sees the individual result
- The team leader or safety manager, by design
- What the employer receives
- Individual risk indication at the point of duty, plus aggregate reporting by cohort, location and craft
Evidence
What we can show
The likelihood limb rests on prior sleep and wake history, the best-evidenced individual fitness-for-duty input available.
The approach follows the published fatigue risk management literature (Dawson & McCulloch, 2005; Dawson & Sprajcer, 2020). The scoring, bands and thresholds are our own, and no validation study is claimed for them.
What it does not establish
It produces a risk indication at role and task level. It does not make a fitness-for-duty determination, does not diagnose, and does not clear or stand down an employee. That decision stays with you, under your own procedure. It is a defensible method, not a validated instrument, and we do not describe it as one.

Was It Fatigue?
Investigate properly when something does go wrong.
See what sleep and fatigue mean for your workforce.
Tell us your industry and roughly how many people you employ. Your snapshot models how many are likely sleeping poorly and what it costs you. Then choose who you’d cover, and we’ll scope the right next step with you: a Fatiguefit Census where fatigue is a safety risk, or a proposal for a wellbeing program.
