Let me offer the analogy of a big, old software project. It is far more difficult to make a major refactor of some 20-year-old, millions-of-lines system than a script you wrote yesterday. That's not saying the old project was incompetent. It could have been very elegant, the best engineering of its day.
For example, suppose you're at a large enterprise that has a silly expense policy involving taping physical receipts to a standard size paper, one receipt per page, then mailing the packet to India, where the pages get scanned and sent to the accounting department, which meticulously compares the receipts against the Excel spreadsheet you filled out and submitted via VBA macros (yes, this is a true story). How easy would that be to change? Compare that experience with working at a 20-person company and asking the accountant if she doesn't mind using Expensify.
Saying that a big company is hard to change isn't necessarily an accusation that the CEO is myopic.
As for what McClure meant by saying public companies will be disrupted... I'm not really sure, since he also contradicted himself saying that they'll purchase their potential disruptors. Perhaps he meant that large enterprises which do not acquire new companies will be out-competed by those who do. That's somewhat of an interesting assertion, but I don't know of any large enterprise that has only an M&A team or an R&D team. They all have both.
In that case I'm sticking to my guns and just disagreeing with you. Many companies are horribly operationally inefficient in many ways, but they often don't care if it's not actively costing them significant market share. The moment that expense report process starts impacting the bottom line you can bet they'll be on the cutting edge of resolving it.
My experience suggests otherwise. Big organizations are bureaucracies carved up into little fiefdoms, each little lord trying to maximize something different. The boss of the receipt scanners wants to increase headcount, not reduce costs. As a management consultant, I encountered that situation time and again -- an executive choosing an outcome worse for the company, knowing it'd be better for him or herself, or simply out of pride, laziness, or malice. There's a reason why Dilbert rings true for so many office workers.
A new CEO can try to clean things up, but they can't fire all the middle management simultaneously, so the ship turns very slowly. Going back to the software metaphor, it's not the issue of short-term vs long-term thinking on patch vs refactor, but the problem that the system is live and must be highly available during maintenance.
Firing all middle management doesn't help: humans are self-interested. What a CEO needs to do is align incentives for middle management with the interests of the firm, so that self-interested middle managers aren't microoptimizing their domains on criteria that don't serve the interests of the company.
That's a good buzzphrase, but I've never seen anyone do it in earnest. I was once on a consulting project to help a "Director" pick appropriate KPIs as part of a company-wide effort to improve departmental performance measurement. They rejected my suggestions to measure their effect on profit. My manager, to rescue the project, told me to ask what they wanted to be measured on, write it down, and hand it back as the report. The Director loved that idea and rattled off a list of metrics that could be easily sandbagged and had no clear relationship with company profit. ... And yes, that company is very large and well-respected.
Only a handful of formidable execs are not stuck in a bygone age, but are still scowling at these tech millennials pulling in millions of revenue because they used unorthodox business methods.
The previous generation needs to catch up. Adapt or begin dying at your own peril.
Let me ask HN a question; when you were 20, did you think you were smarter/wiser than when you were 10? How about when you were 25? Did you think you were wiser than your 15 year-old self? Those of us that hit or broke 30 think we are miles and miles smarter/wiser than our 20 year old selves in exactly the same way we were smarter/wiser than our 10 year old selves when we were 20. That increase in wisdom/life experience does not stop when you hit some magic age. Sure, you may stop growing maturity wise, but you never stop learning. At least I haven't yet, and I'm approaching 40. I look back at my 30 year old self and laugh because I was a complete moron who thought he was starting to finally figure some things out. Nope. Not even close. Still not close yet but I finally understand that you will never have anything figured out.
Millennials take that life experience for granted because they don't have enough yet to even know what it is.
I know a handful of F500 execs, and they are formidable. Sure, they may turn to IT to set up their new "iPhone BlackBerry", but they have tools in their belt to compete with that most valley entrepreneurs don't even know exist.
They were the best, brightest and hardest-working of the previous generation. They are us, with more life experience and better networks. Underestimate them at your own peril. They might be dinosaurs, but who wants to jump in the ring with a velociraptor?
