My question is regarding the difference between capability review as contract review and new product development (design). Our very small company (20 emps.) manufactures mostly to supplied customer specifications. Occasionally, a customer will come to us with something that we have not done before. Depending on the situation, we may have an internal conversation about it and decide that we can produce the part in question. Other times, we may do more elaborate tests/prototypes. We are confused about where the line is between contract review and design. Thanks for any insight.
