Episode notes
Product Trio Owns What Engineers Own How
- The product trio (PM, designer, engineer) owns the what while engineers own the how.
- Teresa Torres argues this boundary prevents PMs from making architecture and sequencing decisions they aren't trained for.
Zero To One Spec Left Engineers Unsure Where To Start
- Teresa describes a PM who wrote specs and iteration plans but whose engineers didn't know where to begin on a zero-to-one build.
- The story shows PMs being pushed into architecture and sequencing tasks they shouldn't own.
IT Mindset Creates Order Taker Engineers
- Treating engineers as an IT cost center creates an order-taker mindset where PMs write tickets and dictate implementation.
- Teresa Torres links this legacy project mindset to blurred ownership, burnout, and poor engineering quality.
