How can PMs survive getting stuck in a waterfall

Lessons In Product Management

In this episode ofLessons in Product Management, host John Fontenot tackles a listener's question:How can a product manager succeed in a waterfall environment? He acknowledges that while Agile is often the preferred framework, many industries and organizations still operate in waterfall models, making adaptability key.

Fontenot offers two approaches:

1. The Ideal Scenario – Where leadership is open to change, product managers can integrate discovery into waterfall planning by validating key assumptions upfront, treating specifications as hypotheses rather than rigid plans, and advocating for continuous learning.
2. The Less-than-Ideal Scenario – When change is difficult, PMs should still find ways to gather feedback on in-flight projects, document assumptions, and leverage data to push for iterative improvements.

His key message: Regardless of methodology, success lies in how PMs use the time between releases to refine strategies and make data-driven decisions.
