Next up is something Burgess calls PPAP, Parts Prior Approved Process. He said this is key to running production. This process startes Feb. 15, 2005.

"PPAP means when we have a new piece of equipment and tooling change, the company has to run several thousand units to ensure we are meeting the standards of the customer. When we get approval from the customer, then we start regular production. We anticipate doing trial runs for three months," he said.

Но там про автомобильное производство речь. А о чем у Вас - контекст бы поширше надо.

Спасибо.
