Product management may be the one job that the organization would get along fine without (at least for a good while). Without engineers, nothing would get built. Without sales people, nothing is sold. Without designers, the product looks like crap. But in a world without PMs, everyone simply fills in the gap and goes on with their lives. It’s important to remember that - as a PM, you’re expendable. Now, in the long run great product management usually makes the difference between winning and losing, but you have to prove it. Product management also combines elements of lots of other specialties - engineering, design, marketing, sales, business development. Product management is a weird discipline full of oddballs and rejects that never quite fit in anywhere else.
