Project manager, product manager, and program manager. Let’s clear that up. A project manager is responsible for shipping a product, whereas a product manager is responsible for making sure the right product is shipped. A program manager is an uber-mutated combination of both that usually shows up to handle multiple interrelated projects like, say, an operating system. Different companies use the names differently, but for this article, project = ship the product, product = ship the right product, and program = ship many interrelated products, usually at the same time. Got it?
