Measures in Product development
 

Hi, I want to know the measures that I should ask a sub–contractor to supply to me if they were undertaking part of a product development which needed to be co-ordinated with my other development activities and also the definition of those measures?

For each measure I propose, why do I want that measures and how
I would use them?. Please help me. I also want to know how to estimate and check the validity of these measures?.

Thank you.
