Overview
MyShyft has developed a workforce scheduling methodology based on ultradian rhythm research that designs employee shifts around natural 90-minute productivity cycles. This science-based approach to shift planning optimizes worker performance, reduces fatigue, and improves overall workforce productivity in shift-based industries.
Scientific Foundation
Ultradian Rhythms in Shift Work
Traditional shift scheduling ignores biological rhythms, leading to:
- Decreased productivity in final hours
- Increased error rates
- Worker fatigue and burnout
- Safety issues
- High turnover
90-Minute Cycle Application
MyShyft applies ultradian rhythm research to shift design:
- Structure shifts around 90-120 minute work cycles
- Schedule breaks at natural energy dips
- Align task types with energy levels
- Respect recovery needs
- Optimize for sustained performance
Shift Design Principles
Cycle-Based Structure
Traditional 8-Hour Shift Problems:
- Continuous work leads to fatigue
- Performance degrades over time
- Last hours are least productive
- Break timing often arbitrary
- Doesn't account for biological reality
Ultradian-Optimized 8-Hour Shift:
- Divided into 4 work cycles
- Each cycle: 90 minutes work + 15-20 minute break
- Total: ~7.5 hours work, 30-40 minutes breaks
- Tasks matched to energy levels
- Maintains quality throughout shift
Break Placement Strategy
Cycle 1 (Start of shift):
- 90 minutes focused work
- 15-minute break
- Highest energy and focus
- Best for complex tasks
Cycle 2 (Mid-shift):
- 90 minutes work
- 20-minute break (includes meal if applicable)
- Still high quality
- Good for important work
Cycle 3 (After midpoint):
- 90 minutes work
- 15-minute break
- Moderate energy
- Routine and collaborative tasks
Cycle 4 (Final period):
- 90 minutes work
- End of shift
- Lower energy
- Administrative and closing tasks

Task Alignment
High-Energy Tasks (Cycles 1-2):
- Complex problem-solving
- Quality-critical work
- Customer-facing activities
- Learning new procedures
- Decision-making
Moderate-Energy Tasks (Cycle 3):
- Routine procedures
- Collaborative work
- Standard operations
- Documentation
- Communication
Low-Energy Tasks (Cycle 4):
- Administrative work
- Cleaning and preparation
- Inventory management
- End-of-shift procedures
- Planning for next shift
Research Support
Research shows ultradian-aligned shifts result in:
- 15-25% higher sustained productivity
- 30-40% reduction in error rates
- 20% improvement in worker satisfaction
- Significant decrease in safety incidents
- Lower turnover and absenteeism
Fatigue Research
- Traditional long shifts without structured breaks lead to cumulative fatigue
- Ultradian breaks prevent fatigue accumulation
- Recovery during breaks restores cognitive function
- Sustained performance vs. declining performance
