Rotation Analytics
Clarity from Complexity.
Our Methodology
How Rotation Analytics examines rotation schedules and classifies scheduling risk for client review.
What We Examine
Each compliance analysis reviews the following dimensions of the schedule.
Individual shift records
Start time, end time, shift type, and total hours for each scheduled shift in the rotation period under review.
Rest intervals
Elapsed time between the end of one shift and the start of the next, assessed against applicable agreement provisions.
Shift type changes
Rapid shift type transitions, specifically night-to-day shift changes, identified and flagged.
Fatigue risk patterns
Shift sequences and rest intervals assessed using a biomathematical fatigue model that quantifies sleep pressure, circadian rhythm disruption, and accumulated sleep debt across the full rotation. Quantified fatigue scoring is available separately through the Fatigue Risk Analysis add-on.
Weekend distribution
Weekends are analyzed using two primary parameters: the minimum hours off required to classify a period as a weekend, and the total number of weekends off within a defined timeframe. Some agreements also require weekends off to be distributed equally.
On-call shift validation
On-call scheduling assessed against collective agreement provisions, including placement relative to off-duty days, frequency, and rest period interactions. This validation is unique to Rotation Analytics
Collective agreement provisions
Scheduling provisions in the applicable collective agreement cross-referenced against the actual rotation record.
Regulatory Reference Points
Each analysis references the applicable frameworks for its jurisdiction and collective agreement.
Provincial employment standards legislation
Applicable collective agreement scheduling provisions
Peer-reviewed fatigue science (cited in applicable findings)
Risk Classification
Two dimensions of scheduling risk.
Compliance analysis and fatigue analysis evaluate different aspects of the schedule and use different risk scales. When both are elected, findings combine to form the complete rotation risk profile.
Compliance Risk
Each scheduling parameter is evaluated against collective agreement provisions, employment standards, and regulatory requirements. Every parameter is first classified as Met or Not Met. Each parameter also carries an impact classification that reflects its significance to the worker on that schedule.
Parameter Status
Parameter meets the required provisions.
Parameter does not meet the required provisions.
Impact Classification
Every parameter carries an impact classification. When a parameter is met, the impact level confirms the significance of that compliance. When a parameter is not met, the impact level indicates how urgently it needs to be addressed.
Critical parameter. Requires immediate attention when not met.
Notable parameter. Warrants review and monitoring when not met.
Supporting parameter. Documented for completeness.
Fatigue Risk
Models physiological fatigue across the full rotation using a biomathematical model validated in occupational health literature. Available as an add-on when elected at submission.
Fatigue scores are classified into five risk levels (Low, Moderate, High, Very High, and Critical) based on the combined effect of sleep pressure, circadian rhythm, and accumulated sleep debt.
