Quick-turn is not just for prototypes these days. It seems like everyone wants their product now. Prototype phases are extremely short these days and customers are wanting production parts rapidly. It leaves little time for process development and validation.
This short time line requires that you do APQP (Advanced Product Quality Planning) up front to ensure you identify all the potential problems or pitfalls you might run into when you race into production. It used to be only consumer electronic devices like cell phones had a short development cycle and life span, but now a lot more industries are adopting and seeing a need to get their next generation products to market quickly.
Up front planning is critical to meet the needs of the Quick-Turn products.
