Firms & operationsProductivity and Profitability Payoffs of Lean OperationsAdopting lean operational practices raised total factor productivity (TFP) by 17% in the first year (p = 0.061; IV coefficient = 0.477, p < 0.05), reduced quality defects by 43%, cut yarn inventory by 21.7%, and generated $325,000 in net annual profit per plant.RCTFirms & operationsManagement Practice Deficit in Developing CountriesAdopting basic quality measurement and data tracking enabled treatment plants to correct defect root causes quickly, reducing average defects by over 50 percent in the first three months alone.RCTFirms & operationsQuality Control and Management Practice AdoptionImplementing quality measurement and analysis systems reduced average defect levels by over 50 percent within the first three months, significantly boosting productivity as nearly 20 percent of the labor force was previously occupied with repairing defects.RCTFirms & operationsStandardized Quality Defect Recording and RemediationImplementing systematic defect categorization and daily record analysis generated a roughly 50% reduction in quality defects, substantially lowering checking and mending overhead.RCT
