I agree that component selection is a multi-department function. Normally, only the design engineers and purchasing team evaluates the components and the production team does not get a say into whether the component is fit to be used in production. I think the input from production and other teams is equally important.
I think for such Component qualification , only design engineer will not be able to complete the whole process. For such a complete qualification, the design has to circulated to various departments such as purchase, production, testing and quality control and finally service.
The 15 points qualification process can thus be divided as below
points 1 to 7 -- purchase
ponits 8 -- production
points 9,10 -- Quality control
point 11 - purchase
point 12 - design engineer
point 13 - purchase.
point 14,15 - testing
Thus once the design engineer has finalised the component selection based upon his requirements and the available alternatives , if the design along with BOM is circulated as per the above route then all the questions related to the suitability of the selected comonent will be answered jointly and a single person doews not have to take the burden .
The departments other than the design department should not take a view that "let the design work first and then we will see the testability, manufacturability and availability"
Douglas, I agree that all the questions are very much valid. But from a developer point of view, how many are following the same? And what’s the reason for others for not following is also relevant. In most of the cases, delay in finding a distributor or component by scrutinizing all the 15 questions is the major factor. The second is we can found out that a very minimal can pass such scrutiny and finally then the selection may be very minimal. In such an environment, we may compromise with some of the factors from the list.
It is good list to follow. But I have not seen so good component engineer so far. For this he has to have 10 to 15 years of design experience. In practice, most work come back to design engineer. He has to reply to all questions.

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
While no one really can accurately predict the future, we can take guidance from another Drucker saying which is the best way to predict the future is to create it.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
