Congratulations! After a long design and prototype verification process, mass production has finally begun for your product.
Let’s imagine that your first batch of a few thousand units sells out in a few weeks (hooray!), you place a bigger order with the manufacturer, and then an even bigger one in a few months. How do you ensure that the 100,000th device coming off the assembly line is the same as the 1000th? How do you catch and eliminate defects? The answers to these questions lie in quality control (QC).
