Intro

Alan Byrne, Product Leader for Mozilla’s Firefox extensions ecosystem, argues that the best product work is less doctrine and more judgement. In conversation with LRandy Silver, he breaks down why prioritisation frameworks like RICE and MoSCoW often masquerade as science while quietly embedding subjectivity—and why he prefers writing clear “what and why” statements over chasing false precision.

From his experience at QuickBooks and Twitter, Alan explores when PRDs are genuinely valuable (complex systems, high risk, trust and safety concerns) and how to keep them lean enough to stay useful. The discussion also digs into the tension between moving a metric and doing right by users, the dangers of gamifying growth, and how product managers can translate customer problems into narratives that align engineers, executives, and sales.
