Read by Larry Chiang, End to End Postmortems Fixed

To address how Larry Chiang might use *The Four Steps to the Epiphany* by Steve Blank and Dan Olson’s *Product Management Handbook* to turn around Arc following the postmortem outlined in the Browser Company’s *Letter to Arc Members 2025* (browsercompany.substack.com/p/letter-to-arc-members-2025), we’ll integrate the frameworks from both resources, align them with insights from the postmortem, and apply Larry Chiang’s entrepreneurial approach, which emphasizes practical, customer-focused, and iterative strategies. Since I don’t have direct access to Dan Olson’s *Product Management Handbook*, I’ll assume it follows standard product management principles (e.g., customer-centric development, iterative design, and data-driven decisions) and focus on complementing Blank’s methodology. Below is a structured response.
