What is product management?
Product management is a professional discipline in product development accountable for creating a viable product business. It can be thought of a scientific approach to converting ideas into viable product businesses. Product management is a part of the product team that defines what the product should be from a functional perspective and works with engineering who implement the product. Product management also works with other product disciplines like sales and marketing to ensure the product is successful.
Product management is practiced differently in different organizations. There is no widely acknowledged central authority that defines the discipline.
