Episode notes

INSIGHT

Premortem As Prospective Hindsight

A premortem uses prospective hindsight to assume failure and work backwards to find causes.
This reduces optimism bias and surfaces hidden assumptions before launch.

ADVICE

Start After Discovery With Clear Objectives

Run a premortem after discovery when objectives and problem statements are defined.
Reiterate objectives and strategy at kickoff so everyone shares the same context.

ADVICE

Collect Stories And Restrict Voting

Collect descriptive failure stories (not keywords) anonymously if possible to foster honesty.
Limit voting (one vote per idea; separate limits for tigers/paper tigers/elephants) to avoid noise.

In this episode, Lily Smith and Randy Silver host Anu Jagga‑Narang, a product evangelist at AT&T, to explore premortems — a powerful technique for anticipating product failure before launch. Anu explains how premortems use prospective hindsight to uncover risks early, surface assumptions teams are reluctant to voice, and improve decision quality.

The conversation covers practical steps for running premortems, risk classification using tigers, paper tigers and elephants, common pitfalls, and when to revisit the exercise as products evolve. They also examine how emerging AI capabilities influence product risk management — increasing the need for thoughtful planning rather than replacing human insight. This discussion offers product leaders a framework to strengthen strategic thinking, foster psychological safety and equip teams to build with confidence and clarity.
