B. mature phase
In the technology product development cycle, the mature phase refers to a stage where key technology has been integrated into many products and has reached
a level of stability and widespread adoption. During this phase, the product has undergone extensive refinement, and its features are well-established. Market saturation may occur as the product becomes widely available and competitors adopt similar technologies. Innovation in the product may still occur, but it tends to be incremental rather than revolutionary. Companies focus on sustaining the product's market position, optimizing production processes, and possibly expanding into new markets or applications. The mature phase is characterized by a balance between supply and demand, and the emphasis shifts from rapid growth to maintaining profitability and market share.
