There are so many job descriptions and blog posts claiming that the product manager is the CEO of the product.
I usually disagree, because the product manager has many more limitation of freedom, compared to a CEO. The role is also somewhat different, though admittedly there are some similarities. Now The Clever PM (who is hopefully also inspired 😉 shows another reason why the product manager is not the CEO of the product: The CEO leads by authority, the Product Manager leads by influence. How true this is.
