Prioritization: The Core PM Skill
If product management had a single defining skill, it would be prioritization — and its essence is a word most people find hard to say: no. There are always more things to build than time to build them, every one championed by someone, and the PM's job is to choose the vital few and decline the rest. Done well, prioritization focuses a team's finite energy on what matters most. Done poorly — or avoided — it spreads the team thin across everything and accomplishes little.
