@Sean - this was not about being band 7 or 8. This conversation started about having body regulating medical device engineers, where they follow a structured training program to understand the fundamentals when they enter the industry.

How can you have a entry level engineer working on anesthesia or ventilation without understanding the principles and fundamentals.

It seems you have misunderstood this and drifted into a managerial capacity. I am looking further than my nose, you did call it a 'greasy pole of advancement' and by following a BMET structure this will look out for the future of this profession.
