Anyone who built software for a while knows that estimating how long something is going to take is hard. It’s hard to come up with an unbiased estimate of how long something will take, when fundamentally the work in itself is about solving something. One pet theory I’ve had for a really long time, is that some of this is really just a statistical artifact.
Product managers, among other things, specialize in building bridges between the very general (e.g, a vision for changing the world), and the very specific (e.g., functional requirements for a single button). Ironically, the discipline of product management itself is missing this bridge. We lack a clear framework for connecting the high order duties of product management with the day-to-day realities of execution. I’ve invented the graphical model of the product management triangle to be this bridge and provide a foundation for deeper exploration into product management topics.
