Teresa Torres introduces the product trio: a product manager, designer, and engineer who share responsibility for product decisions rather than handing work off in sequence. She argues the traditional handoff model causes rework, budget overruns, and missed scope because teams don't learn what's feasible until late. Drawing on Marty Cagan's distinction between mercenary and missionary teams, she contends that shared customer understanding produces better products. The trio interviews customers, maps opportunities, and iterates on solutions together. The piece closes by encouraging readers to move incrementally toward this collaborative model.
01Key takeaways
- Sequential handoffs between PM, design, and engineering often cause rework, budget overruns, and late delivery.
- Involve engineering and design early so feasibility and customer insight shape what gets built.
- Build a shared understanding of customers, their opportunities, and the context around them.
- Make product decisions jointly across the trio rather than having one role write requirements for the others.
- Start small by collaborating more closely with peers and improving incrementally each week.
02Key sections
- What a product trio is
- A product trio is the minimum set of roles, a product manager, designer, and software engineer, needed to build good digital products. The section contrasts this with the older model of sequential handoffs.
- Problems with handoff-based work
- Sequential handoffs cause product managers to write requirements without knowing feasibility, leading to repeated rewrites and projects that run over budget and late. The result is teams that act as mercenaries rather than missionaries.
- Missionary teams and shared understanding
- Great products come from missionary teams that have a voice in what they build. Teams need a shared picture of their customers, their opportunities, and the context in which those opportunities arise.
- How the trio works in practice
- Trio members jointly interview customers, map the opportunity space, choose a target opportunity, generate solutions, and test them. They collaborate from start to finish.
- Getting started
- Torres encourages readers not already in a trio to work more closely with their peers and to pursue continuous improvement rather than perfection.
