In Simple Words
Instead of judging an object solely by its price tag, a panel of master craftspeople systematically checks every component—from corner alignment and weave tightness to surface texture—to calculate an accurate overall grade.
Small rug firms in Fowa
- No export opportunity offered
- Average quality score 2.96
- Export opportunity offered
- Quality score 0.79 points higher
Master artisans scored export-offer firms 0.79 points higher on the 1 to 5 quality scale; comparison firms averaged 2.96. Master-artisan scores on a 1 to 5 scale. Trial firms surveyed between 2011 and 2014.
See source →Research question
Product quality in micro-enterprise manufacturing is difficult to measure using market prices alone, making it challenging to evaluate whether development programs achieve actual technical upgrading.
Participants
N = 219 small rug producers (74 treatment, 145 comparison) in Fowa, Egypt.
Study Design
Randomized Controlled Trial using intermittent double-blind evaluations by master artisans scoring rugs across 11 physical criteria on a 1 to 5 scale over three years (2011–2014).
Results
Exporting firms scored 0.79 points higher overall than comparison firms (which averaged 2.96 points), demonstrating measurable physical quality improvements in areas like corners, waviness, and touch.
Takeaway
Deploy independent expert evaluators to score artisanal product upgrades across standardized structural dimensions rather than relying strictly on gross revenue or sale prices.

- 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.
