Product Line (PL) in Product Management is a set of related products that are marketed together as a group. It is a way to organize and manage products within an organization. Product lines can be used to differentiate products, create brand loyalty, and increase sales. They can also help to reduce costs by allowing for economies of scale in production and marketing. Product lines can be based on product type, customer segment, or any other criteria that makes sense for the organization. A product line typically includes multiple versions of the same product, such as different sizes or colors, as well as accessories and complementary products. The goal of product line management is to maximize the profitability of each product within the line while ensuring that all products are consistent with the overall brand strategy.
