In Simple Words
Imagine a hardware store where nails, screws, and tools are thrown into random unlabeled boxes on the floor. Customers wait in long lines while clerks dig through boxes to find a single bolt, and the owner accidentally reorders items that are already sitting buried under dirty rags. Labeling every shelf and setting a clear rule to reorder when stock drops below a marked line lets clerks grab parts instantly and prevents buying duplicate inventory.
Textile plants near Mumbai
- Diagnostics and light advice
- Group used for comparison
- Added implementation help
- Productivity 16.6% higher
The card states the whole-program productivity result. Inventory control was one of 38 practices and was not tested separately. First-year whole-program comparison. Inventory control was not tested separately; absolute productivity not reported. Both groups received diagnostics and light follow-up advice; treatment plants received added implementation help.
See source →Research question
Industrial plants frequently store raw materials, spare parts, and finished yarn in disorganized, unlabelled areas without standardized inventory tracking. This lack of organization causes workers to waste time hunting for components and leads to excessive working capital locked up in unnecessary stock.
Participants
N = 17 large manufacturing textile firms (28 factory plants) around Mumbai, India, averaging 270 human workers and US$13 million in assets.
Study Design
Randomized Controlled Trial (RCT) where consultants assisted treatment plants in establishing systematic storage organization and inventory control norms over a 4-month period.
Results
Establishing formalized storage systems and inventory norms reduced material search delays and excess working capital, contributing to a 16.6% productivity increase within twelve months.
Takeaway
Designate specific, labeled storage locations for all raw materials and spare parts, establishing minimum and maximum buffer stock norms for reordering.

- 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.
