Any number of organizational configurations involving engineers, product managers, and designers can produce successful products. Over the past three decades, my observation is that the companies that have let the builders — the engineers and the designers — own significant parts of the role of Product Manager produce stronger products. You want the humans building the product to have an equal voice in product decisions. You want the hard decisions to painfully earn their resolution through long hours of informed humans staring at the problem from every angle. You want humans who build. And you don’t need Product Managers.
