From what I understand MBA-fication of innovation is inevitable. Innovation is funded by revenue and revenue is backed by sales. Sales is driven by "who you know" aka networking.
Technical prowess will convince someone to buy your product, but networking gets you through the doors in the first. Inevitably you need MBAs to generate revenue. After a certain points MBA-fication creeps in to engineering decisions and innovation.
From what I understand, innovation is largely fueled by chaos and risk. MBA fundamentally is about risk minimization and certainty. So, I can't blame Boeing, like I can't blame Intel, IBM, Ford, GM, General Electric, Phillips etc.
