Fatigue Science’s Readi vs Sleep Intelligence
Which is the right fatigue risk management system (FRMS) for your company?
While both Fatigue Science’s Readi platform and Sleep Intelligence aim to address fatigue risks in mining and transportation, discover how they differ in their approach, features, and technology.

Readi Overview
Readi fatigue risk management software provides predictive insights into driver and operator fatigue, allowing you to mitigate fatigue risk before it becomes dangerous.

Readi Key Differentiators
Predicting Fatigue Risk for the Entire Shift
Hour-by-hour, predictive personalized fatigue scores for every driver for up to 18 hours, allowing a manager to assess the risk across the operator’s entire shift
Fatigue Forecasting
Readi offers fatigue forecasting not only for the shift but also for the next 14 days, enabling more proactive shift scheduling and fatigue management
Sleep Data Metrics
Readi measures quality, quantity, and accumulated sleep debt to create more accurate fatigue scores for individual operators
Impact Analysis
The Readi system is the only FRMS that has the ability to connect a driver’s fatigue scores to safety events (e.g., harsh braking, speeding), allowing operations leaders to quantify the impact of mitigating operator fatigue across the organization.
Validated Technology
Validated by the US Department of Transportation, the Federal Aviation Administration, and the US Army

What’s Included: Readi vs Sleep Intelligence
Fatigue Science’s Readi fatigue risk management system includes:
With the ReadiWatch and ReadiOne app, operators receive predictive fatigue scores and alerts throughout their shift, allowing them to take mitigating actions in advance.
Through ReadiSupervise, supervisors receive fatigue predictions and alerts well in advance (up to 18 hours before a shift). This allows for proactive management of workforce fatigue risk, ensuring adjustments are made long before an employee reaches a critical state.
ReadiAnalytics provides leadership with comprehensive insights through predictive data analytics. This includes historical data, future fatigue predictions, and real-time insights into workforce fatigue. Managers can view fatigue metrics across locations, shifts, and individual workers. Additionally, custom BI integration allows data to be modified and analyzed further within third-party tools.
Sleep Intelligence provides:
iSleep Wearable: A basic device designed for sleep capture and monitoring that delivers minimal analysis focused on sleep quantity.
Covid App: Additional tools that provide proximity and COVID-related analysis.
Overall Offering: Positioned as a cost-sensitive, “box-ticker” solution, it delivers only essential functions. Its content and analysis capabilities are notably outdated and lack the depth required for comprehensive fatigue management.

Validated Technology
The ReadiScore has been validated extensively by the US Dept. of Transportation, the Federal Aviation Administration, and many other public and private institutions.
The ReadiScore is the output of the SAFTE Biomathematical Fatigue Model, which was developed by researchers at the US Army’s Walter Reed Army Institute of Research. It has been studied and validated in 13 published independent papers. Our fatigue risk prediction has a validated 92% accuracy level.
Sleep Intelligence’s technology has not been independently validated by reputable authorities, and there are no published studies confirming its predictive accuracy. This absence of rigorous validation means it may not deliver the reliable fatigue insights needed for high-risk operations.

Impact Analysis
The Readi system has the ability to connect a driver’s fatigue scores to safety events to quantify the impact of fatigue mitigation on the organization.
A recent meta-study found that Readi could reliably predict if and when a driver would experience a 12x higher incidence of microsleeps vs. their baseline rested state. Additionally, the US Dept. of Transportation published a study revealing a 7.3x higher accident cost in cases where the ReadiScore had predicted high fatigue.
Similarly, two telematics studies conducted by Fatigue Science clients showed 8.5x higher incidence of harsh braking and a 4x higher incidence of speeding in cases where Readi had predicted high fatigue.
Sleep Intelligence does not offer any impact analysis capabilities. It cannot correlate sleep or fatigue metrics with actual safety events, limiting its usefulness in proactive risk mitigation.

Full Cycle FRMS: Predicting Fatigue Risk Is Only the Start
Readi provides an organization with a full Fatigue Risk Management System. This means that a user can start and finish the fatigue workflow within the tools:
-Identify fatigued drivers
-Conduct a fit for duty assessment
-Evaluate and assign mitigations actions
-Analyze historical data to assess effectiveness of the actions and adjust policy and procedure accordingly
Sleep Intelligence provides only a basic sleep tracking and analysis function. It is not designed as a full cycle FRMS and does not support the comprehensive fatigue management workflow needed to effectively mitigate fatigue risks.


FAQ
What is a Fatigue Risk Management System (FRMS)?
An FRMS is an integrated approach to proactively manage fatigue risk using predictive analytics, monitoring, and actionable insights. Fatigue Science’s Readi delivers a complete FRMS solution that covers every step of fatigue management—from prediction to mitigation.
Why is validated technology important in fatigue management?
Validated technology ensures that fatigue predictions are based on rigorous scientific research and independent testing. Readi’s technology is backed by independent studies and validated models, while Sleep Intelligence has not been independently verified, potentially compromising its reliability.
What are the main benefits of using Fatigue Science’s Readi?
AReadi offers personalized, hour-by-hour fatigue risk predictions up to 18 hours in advance, robust integration with safety and dispatch systems, validated accuracy, and a complete FRMS that links fatigue scores to safety events, ensuring a proactive approach to risk management.
Is Sleep Intelligence a complete solution for managing fatigue?
No. Sleep Intelligence is a basic, cost-sensitive solution that focuses on minimal sleep tracking and analysis. It lacks comprehensive features such as impact analysis, validated technology, and a full-cycle FRMS, making it less suited for organizations that require serious fatigue management.
What happens if a pilot using a basic solution like Sleep Intelligence fails?
Organizations that choose a basic solution based solely on cost may soon find that it cannot effectively manage fatigue risks. Fatigue Science’s Readi is designed to provide long-term, reliable fatigue management, ensuring your company is protected even when basic pilots fall short.

Manage and Mitigate Driver Fatigue with Fatigue Science
While Sleep Intelligence offers a cheap, basic solution that ticks some boxes, it falls short on the robust, validated, and predictive analytics needed for true fatigue risk management.
If decisions are based solely on lower price, it may indicate a lack of commitment to serious fatigue management. Fatigue Science’s Readi has consistently proven its worth in the field—and we’re here for the long haul, even when pilot projects using basic solutions inevitably fall short.
