Hello, Currently we are on the way to deploy APQP process with our supplier for my company automotive project. There are something as below: 1. I'm reviewing a supplier timeline and have a concern as below: as you know, in PTO we need to get samples from supplier to proceed it. Sample should satisfy DIM,Function & Material, the problem is i don't know how to define those samples is affordable to be used for PTO base on above criteria. Could you give me some recommendation ? 2. Could you give me your general opinion how to manage Supplier APQP process best to meet project timeline. I went through many resources like [Covoco Pricing](https://covoco.com/voice-over-pricing.php "Covoco Pricing") but did not find much about this. Can you help? . If anyone can suggest me it would be great. Any assistance gratefully received! Thank you
