Workforce Scheduling Optimization

A peer-reviewed field experiment published in Management Science in 2022 provides rigorous evidence of scheduling optimization benefits. Researchers from the University of North Carolina, the University of Chicago, and UC Hastings conducted a randomized controlled trial at 28 stores of a national apparel retailer in San Francisco and Chicago between November 2015 and August 2016, evaluating more than 150,000 shifts across 1,500 employees. The 19 treatment stores that adopted stable, predictable scheduling practices saw store productivity increase by 5.1%, driven by a 3.3% increase in sales and a 1.8% decrease in labor costs. Median sales rose by 7% in treatment stores during the intervention period, a significant result in an industry where annual sales growth of 1% to 2% is typical. The study also found that fluctuating customer demand explained only 30% of the variability in weekly payroll hours, challenging the assumption that schedule instability is an unavoidable consequence of retail volatility.

At the enterprise scale, the nation's largest general merchandise retailer, employing over 1.5 million U.S. associates, reported in June 2025 that AI-powered scheduling tools reduced the time team leads spend planning shifts from 90 minutes to 30 minutes. The Retail Industry Leaders Association's 2025 report found that major U.S. grocery chains adopting predictive scheduling achieved labor efficiency gains of up to 15%. Separately, a 2021 Forrester Consulting Total Economic Impact study of an AI-native workforce management platform modeled a composite organization with 9,000 hourly workers across 500 locations and projected $13.35 million in net present value benefits over three years, with 46% of savings attributable to improved scheduling optimization through more accurate forecasts and AI-powered labor planning.
