In Simple Words
Think of a carpenter who learns advanced techniques and is immediately assigned to carve intricate custom cabinets rather than assemble simple wooden chairs. Their total output of finished items per day might appear constant or drop slightly, but the overall technical value and complexity of what they build for the workshop increases significantly.
Women garment workers in Bengaluru
- No training on control lines
- Comparison group
- P.A.C.E. soft skills training
- Assigned more complex tasks
After training: task benchmark time rose by 0.0384 minutes, about 2.3 seconds. This is expected task time, not actual time spent.
See source →Research question
When frontline workers undergo skill training, line supervisors may reassign them to higher-complexity tasks, making raw output metrics misrepresent true efficiency gains if task difficulty is unmeasured.
Participants
N = 2,703 female garment workers across 112 production lines generating 290,763 daily observations in Bengaluru, India.
Study Design
Two-stage randomized controlled trial (RCT) using tablet-recorded daily operations linked to industrial engineering Standard Allowable Minutes (SAM) benchmark data.
Results
Soft skills training significantly increased assigned task complexity, raising operation SAM by 0.0384 minutes post-treatment (p < 0.05; relative to a control baseline mean of 0.565 minutes), demonstrating that supervisors systematically assigned soft-skilled workers to more complex sewing operations.
Takeaway
Adjust worker productivity evaluations by controlling for task-level Standard Allowable Minutes (SAM) to isolate true efficiency gains from task complexity reassignments.

- Randomized controlled trial
A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
