Yes, and this is exactly when you have ineffective PMs, and senior leadership isn't paying attention. With a good product and design team, I have been part of engineering teams that have 5 engineers than can do the work of 20, without working overtime, consistently deliver, and rarely, have to implement anything twice. The difference between effective product and not is absolutely night and day. The best analogy is driving a modern car, vs driving a modern car without vehicle stability, anti-skid, power steering, automatic transmission, or AC. Sure you absolutely can drive it, but after a while you will need way more breaks than those who have all the nice features, and won't roll over in bad situations.
