What does a product manager do?

7 perspectives · Updated · 3 min read

Ask what a product manager does and you'll often hear about roadmaps. The CEOs here start with the decision behind the roadmap.

Matt Mullenweg, who was a product manager at CNET, says the hard part is translating user pain and company goals into something a team can ship. Jason Lemkin says the job starts with spending more time with customers than anyone else.

Their answers cover deciding what to build, working with customers, and keeping a team focused.

The short answer

A product manager decides what gets built, for whom, and why, then gets engineering, design, and the business behind that decision. These CEOs add two parts: time with customers to learn what they need, and checking the usage data afterward to see if it worked.

Matt’s advice: Decides what gets built and why, then rallies design, engineering, and the business.

A product manager is the person who decides what gets built and why, then rallies design, engineering, and the business around that decision. When I was a PM at CNET, I learned that the hardest part isn't the roadmap; it's translating user pain and company goals into something a team can ship.

Bill’s advice: Owns what the team makes, for whom, and why it wins, then keeps the focus on a few things.

A product manager owns the answer to what are we making, for whom, and why it wins. They translate customer pain and business strategy into a roadmap, then fight to keep the team focused on the few things that actually move the needle.

Vishen’s advice: Translates the founder's vision into clear user problems and priorities.

A product manager is the translator between the founder's vision and the team that builds it. They take what the founder sees in the field, turn it into clear user problems and priorities, and make sure engineering, design, and QA ship solutions that actually land.

Kian’s advice: Turns customer pain into decisions, then watches usage data to check the bet.

A product manager translates a real customer pain into a decision framework the squad can execute against, then lives inside the usage data to see if the bet was right. At Workera, our PMs sit in trios with design, engineering, and AI, and their job is to make sure we ship what moves the customer outcome, not what moves the roadmap.

What a product manager does, step by step

  1. Talk to customers. Jason Lemkin says a product manager should spend more time with customers than anyone else and figure out what they need.

  2. Decide what to build and why. Andrew Feldman, Matt Mullenweg, and Bill Canady all put this decision at the center: what, for whom, and why.

  3. Turn it into priorities a team can ship. Vishen Lakhiani calls the product manager a translator, turning what the founder sees into clear user problems and priorities.

  4. Get everyone behind it. Andrew Feldman says engineering, sales, marketing, and customers should all line up behind the decision.

  5. Cut what doesn't serve the user. Matt Paulson's product calls come down to one core user behavior loop. Bill Canady keeps the team on the few things that move the needle.

  6. Check whether it worked. Kian Katanforoosh's product managers live inside the usage data to see if the bet was right.

Where they disagree

They agree on the core and differ on where a product manager's input starts. Jason Lemkin and Kian Katanforoosh start with customers. Vishen Lakhiani starts with the founder's vision and has the product manager translate it. Bill Canady adds business strategy and asks why the product wins.
