I can remember many years ago when we where working with very limited resources a New Guy fresh out of Uni was given a job of rewriting a subroutine for a engine management system to bring a Turbo Engine off Idle without a Flat Spot in the Acceleration Curve.
It was a very minor thing and he proceeded to rewrite the sub in a different language which took 3 times the available Memory of the entire device. When he was confronted with the most obvious problem he response was that it wasn't a Software Issue but a Hardware Issue and we needed to redesign the existing hardware so that we could make use of his code.
I've seen way too many examples of kids fresh out of Uni who know it all and can not be corrected, it's Their way or the Highway no matter what and as they have a Brand New Degree they believe that they know far more than the Old Fogies who are doing the work successfully and they should be promoted to a Leadership Role while those who are already there should be demoted till they learn to do things the way of the new staff member.
If you want to interview people like that way too many will believe that the company has no interest in Innovation or improving itself but the reality is that it's far easier to rewrite a bit of software than redesign the hardware and it's far cheaper. In the above case the product we sold was already the most expensive bit in most race cars after the engine and this Kid wanted to Quadruple or much likely more the cost of our product even though it was at that time not possible to make the hardware to his requirements. Back then we used EPROMS to hold the Code that allowed quick and cheap Redesign to suit the power characteristics of different engine types or even different engines from the same maker. There was no alternative to use anything else that would remain Nonvolatile and reliable then.
Of course those with long term experience of the business who are asked to offer their opinions are a different story but as there was no qualification of those complaining that their opinions where not accepted I tend to believe that a lot of those complaining are new fresh out of Uni types who Know it All and can not have their opinions altered.
