The product lifecycle is a fundamental concept in product management, which refers to the stages a product goes through from its inception to its retirement. Understanding this lifecycle is critical for product managers, as it allows them to make informed decisions about product development, marketing, and sales strategies. This glossary entry will provide a comprehensive overview of the product lifecycle and its implications for product management.

Product managers are responsible for guiding the success of a product and leading the cross-functional team that is responsible for improving it. This role spans many activities from strategic to tactical and provides important cross-functional leadership — most notably between engineering, marketing, sales, and support teams. As such, understanding the product lifecycle is crucial for product managers to effectively carry out their duties.

Conceptualization

The first stage of the product lifecycle is the conceptualization stage. During this stage, product managers identify a market need or opportunity and develop a concept for a product that can meet this need or capitalize on this opportunity. This involves conducting market research, identifying target customers, and defining the product's unique selling proposition.
