A product line refers to a group of related products offered by a company under a single brand or category. These products share similar features, functions, and target markets, but may vary in size, style, or price. A well-developed product line allows a company to cater to different customer needs and preferences, while maintaining a cohesive brand image. It also enables the company to efficiently utilize its resources and production capabilities, resulting in cost savings and increased profitability. A successful product line is often a key factor in a company’s overall success and market competitiveness.
