Fatigue management software
Fatigue Management is roster software for organisations managing shift-based and operational work. It connects planned duties, modelled fatigue exposure, named policy checks, and documented management decisions.
Roster planning
Section titled “Roster planning”Create and edit planned shifts, recurring series, open work, assignments, staffing levels, and planned one-way travel. People and reusable work locations are maintained separately from application members.
The roster can be reviewed in a week overview or a timeline.
This example week is fictional and simplified. Moving a duty recalculates modelled FI and RI.

Fatigue assessment
Section titled “Fatigue assessment”Fatigue Index and Risk Index are recalculated when fatigue-relevant roster information changes. The calculation follows an RR446-compatible method.
Break, workload, and attention values use the documented RR446 defaults. The values applied to each evaluation are retained with the result.
Methodology and model limitations explain what those outputs mean.
Policy evaluation
Section titled “Policy evaluation”When a named policy profile is active, the software shows the triggered conditions, measured values, thresholds, reasons, and the relevant duty context.
The current optional profile is Rail reference profile 1.0.0. It is a product reference profile, not an HSE, ORR, RSSB, or Network Rail standard or approval. Organisations without an active profile continue to receive modelled FI and RI with a clear “No active policy” state.
Rule evaluations are scoped to the active, named policy profile.
Management decisions
Section titled “Management decisions”Routine outcomes remain one-step. Managed Level 1 requires an authorised management reason. A Prohibited result under the active profile cannot be overridden within the workflow.
Owner, admin, manager, planner, and viewer roles are separated inside one organisation workspace.
Records
Section titled “Records”Each evaluation is retained as a record of the roster facts, model result, active profile and decision at that point in time. Relevant changes and governed decisions are recorded with that evaluation.
Methodology
Section titled “Methodology”Fatigue assessment and policy evaluation are treated separately. FI and RI are modelled estimates. The active profile determines which organisational conditions are triggered. Management decisions are retained separately from the model output.

Pricing
Section titled “Pricing”Fatigue Management Workspace is £5 per managed worker / month. Application users are included. There is no free trial. Taxes are applied where legally required. Create a workspace in the application, add managed workers, and start the subscription. Published price examples do not set the billed quantity. Paid use is covered by the Workspace Subscription Terms. For procurement questions, contact us.
Open the application
Section titled “Open the application”The application is available at app.fatiguemanagement.co.uk. Authentication is handled there, not on this website.
From spreadsheets and standalone calculators
Section titled “From spreadsheets and standalone calculators”A spreadsheet can hold a shift plan, and a standalone calculator can assess a set of inputs. This workspace connects the plan to its evaluations and decisions:
- Changes to fatigue-relevant roster information trigger recalculation of FI and RI.
- Named policy checks keep measured values, thresholds and reasons alongside the duty context.
- Organisation roles distinguish planning, management approval and administration.
- Retained evaluation records connect roster facts, model results and decisions at that point in time.
These capabilities support documented decision-making. They do not replace a fatigue risk assessment or competent-person judgement.
Who it is for
Section titled “Who it is for”The roster and assessment workflow is written in internationally neutral language. The current named governance profile is rail-oriented and UK-scoped.
Questions
Section titled “Questions”Is this an FRI calculator?
Section titled “Is this an FRI calculator?”It includes modelled FI and RI, connected to planned shifts, recent duty history, an optional rule profile, governed outcomes, and retained evaluation records.
Does it guarantee compliance or safe rosters?
Section titled “Does it guarantee compliance or safe rosters?”No. Compliance depends on the applicable rules and how they are implemented. Model outputs and policy checks cannot establish individual fitness for duty.
Is the product available outside the UK?
Section titled “Is the product available outside the UK?”The general roster and fatigue-assessment workflow is not presented as UK-only. The current named governance profile is specifically rail-oriented, and no non-UK compliance claims are made.
