Good Product Manager / Bad Product Manager

Ben Horowitz's "Good Product Manager/Bad Product Manager" is considered a foundational text, akin to a bible for product managers. Despite being over 15 years old, it remains a crucial resource, defining the core qualities and practices that separate effective product managers from ineffective ones.

It's valued for its clear distinction between proactive, vision-driven product leadership and the pitfalls of a lack of clarity and execution.
