Walk into any small-scale manufacturing unit in Gujarat, Maharashtra, or Tamil Nadu. You'll see something remarkable: rows of workers meticulously examining each component, running their fingers over surfaces, holding parts up to light to catch imperfections.
This is visual inspection — the backbone of manufacturing quality. And it's entirely dependent on human eyes, human attention spans, and human fatigue.
The numbers tell a brutal story:
- 2-5% defect rates in manual inspection (even experienced inspectors)
- 15-25% of production time devoted to quality checks
- 60-70% of customer complaints stem from manufacturing defects
- Indian MSMEs lose ~$12 billion annually to quality-related issues
