To be fair MBAs and consultants are very important as well. And legal people as well. Many great engineering marvels never made a profit or never saw the market at all. Just look at soviet airliners. But within a certain balance a strong engineering weight is important. And a long term strategy with big investments permitted beyond fearing for the next quarterly figures. It would be perfect to motivate the top people not only by bonuses for having pleased the stock market but maybe more for technical innovation, safety, employee and customer satisfaction, number of new orders coming in etc.
