Excuse me for asking, but where were manufacturing / purchasing representatives during R&D stages design reviews and risk analyses? Further, such a generic requirement probably belongs in the R&D design checklists in the first place.
The organizations I alluded to were, for the most part, post (not by much) start-up phase. They were in the late stages of product validation, post prototyping. They did not have full fledged production operations. Since most of their processes were still around R&D, and their personnel did not have a lot of experience with volume production, it did not cross their minds about this specific challenge.
Also, remember that, depending on the type of the product, an R&D cycle can take many years. The early stages of the Research is pure conceptual tinkering. Manufacturing, Purchasing, Quality, etc. are DELIBERATELY left out of the process not to "hinder" the scientists creative juices....
Sometimes, there is a price to be paid.
?!?
inspite things said in a previous post), then a "live and let live" approach towards R&D is the most sensible and profitable one (long-term). Challenge their decisions on design reviews, make them document and justify everything (doesn't have to be lengthy), but don't overload with unnecessary procedures and rules.
