Product management is the business process of planning, developing, launching, and managing a product or service. It includes the entire life cycle of a product, from idealization to development to go to market.
A product manager is the person who identifies the customer need and the larger business objectives that a product or feature will fulfill, articulates what success looks like for a product, and rallies a team to turn that vision into a reality.
Product managers are responsible for ensuring that a product meets the needs of its target market and contributes to the business strategy, while managing a product or products at all stages of the product life cycle. Software product management adapts the fundamentals of product management for digital products.
