Task Complexity Reallocation via Standard Allowable Minutes
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.
Picture this
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.
What the evidence says
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.
- Who
- N = 2,703 female garment workers across 112 production lines generating 290,763 daily observations in Bengaluru, India.
- How
- Two-stage randomized controlled trial (RCT) using tablet-recorded daily operations linked to industrial engineering Standard Allowable Minutes (SAM) benchmark data.
What to do
Adjust worker productivity evaluations by controlling for task-level Standard Allowable Minutes (SAM) to isolate true efficiency gains from task complexity reassignments.
From the source
"Treated workers are more efficient after the program... despite being assigned to more complex tasks... SAM measures task complexity, and efficiency is actual pieces produced divided by target pieces."
