What is a Product Line?

Companies usually become successful in business by having a product line and selling the brand successfully. The definition of a product line is several closely related products grouped under one brand and sold by the same company for the same market. It is a collective of similar products being sold to the consumers.

The main characteristics of a product line are outlined below:

  • Product lines are composed of similar items. The reason for offering similar items is to give consumers a variety of choices and to create and maintain a good reputation.
  • The items in a product line are closely related. They only differ in size, color, model, capacity, weight, and performance.
  • The products also complement each other. A tire, a tube, and related products complement each other, for example.
  • Product lines usually use the same distribution channel for the products. This means that similar outlets market the products.
  • The products usually attract a similar group of customers. Hence, they are sold to a similar group of customers.

Companies sell many product lines under various brand names, and the products are mainly differentiated by quality, price, and targeted demographic. There are different brand types: corporate brands, product brands, personal brands, service brands.

  • Corporate Brands: This type of branding is a method used by companies to market themselves and outstand the competition. Decisions in this branding include pricing, target markets, and values
  • Product Brands: This branding involves marketing one specific product.
  • Personal Brands: Branding is not limited to companies. People also use marketing tools, like social media, to boost their branding.
  • Service Brands: This branding applies to services that require a lot of creativity since it is impossible to show the services physically.

The product line constitutes the product and product management. Product management is led by a product manager responsible for every step of the product cycle. Some product line manager roles are allocating funds needed to market the product, conducting research, and deciding whether to contract the product line. The main factors that categorize products into product lines are their price range, brand, or functionality. Companies prefer product lines since by creating them, they can capture customers who are already buying their brand.

Product Life Cycle

A product life cycle is described as the amount of time a product stays in the market from its introduction until it is removed. A product life cycle works in four stages: introducing the product to customers, growing the product, maturity of the product, and finally, its decline.

  • Introduction: At product introduction, advertising and marketing is done to lure customers and make them aware of the new product and how it will benefit them.
  • Growth: At the growing stage of the product, the product is in constant demand, meaning it is increasing in production and gradually expanding in operations.
  • Maturity: In the maturity stage, the product has the maximum profits return and has a firm grasp of the consumers' needs and acquisitions. There is new competition at this stage. Prices decline because some consumers have found alternatives, increasing the possibility of sales reaching a plateau or a peak.
  • Decline: In the decline stage, competition from other companies starts to kick in, and the company loses market shares and starts declining.

Product lines and product life cycles are closely connected. After a product life cycle declines, a company should introduce a product line to ensure the customers who were buying their brand will continue buying from them. Therefore, grouping several products in a single brand will ensure the product begins the introduction phase again. For example, Coca-Cola has remained in the market because it adds a new drink to its portfolio under the same brand name regularly. While some of these drinks are closely related to the Coca-Cola brand, others are in entirely different categories.

Product Line vs. Product Mix

A product line is a set of similar products manufactured and sold by a single company. On the other hand, a product mix is the total of every product line that a company develops and sells. A product mix is characterized by its depth, length, consistency, and width.
