Product management is a discipline best learned by apprenticeship because it is first and foremost about pattern recognition – recognizing patterns of customer problems, markets, sales challenges, and priority conflicts inherent in a product life cycle. In short, the skills of product manager are all about judgment – demonstrating consistently excellent judgment as you apply and demonstrating mastery of a broad set of interdisciplinary leadership, technical, marketing, business strategy and common sense skills. These are required skills of product manager.
