The core job of a Product Manager is not writing specs or talking to press; it's a leadership role. Success means getting a product to market that wins. This requires influencing engineering, marketing, and sales without any formal authority, making it the ultimate training ground for real leadership.

In a truly product-led company, the product organization must accept ultimate accountability for business-wide challenges. Issues in sales, marketing, or customer success are not separate functional problems; they are reflections of the product's shortcomings, requiring product leaders to take ownership beyond their immediate domain.

A true product-led culture doesn't mean the product team dictates decisions. Instead, its primary function is to surface and clearly frame cross-functional tensions and trade-offs, enabling the entire organization to make cohesive, system-wide decisions.

Product managers operate as internal ambassadors, responsible for outcomes like budget and sales but without direct authority. Success depends on building relationships and influencing functions like cost accounting, engineering, and other product teams to achieve shared goals.

The 'CEO of the product' metaphor is misleading because product managers lack direct authority. A better analogy is 'the glue.' The PM's role is to connect different functions—engineering, sales, marketing—with strategy, data, and user problems to ensure the team works cohesively towards a shared goal.

On the Codex team, the PM role is not seen as a traditional leadership position. Instead, it's a support function focused on doing whatever is necessary—bridging gaps, coordinating, and sometimes criticizing—to help the team succeed, rather than directing strategy from the top.

The ultimate sign of a product manager's influence is not receiving feature ideas, but being the go-to person for complex business problems. This indicates you are viewed as a strategic partner capable of diagnosing root causes, even when a solution isn't obvious.

Frame the product manager not as a feature owner, but as the central communication hub. Their primary function is to connect business, stakeholders, engineering, and design, navigating complex relationships and translating needs across disparate groups.

Unvalidated product ideas often originate from executive leadership or adjacent departments. A product manager's critical role is to use disciplined stakeholder management and clear communication to maintain focus on solving validated user problems, rather than simply executing on top-down directives.
