What is a Product Line? Definition, Decisions, Importance, and Examples

A company can not succeed in the long run if it sells only one product and does not make additional changes and modifications to the product. For this companies need to adopt the product line, which is a strategy for businesses to introduce groups of similar products targeting the same audience with differences in price, quality, and other attributes.

Let’s understand what are product lines, their examples, types, and importance.

What is a Product Line?

A product line is a group of related products marketed and sold by a single company targeting similar segments of the market.

Product lines are groups of interrelated products fulfilling the identical needs and want of customers. Take the example of Apple’s product line iPhone – it annually updates and launches a new iPhone model, which is a part of Apple’s line strategy.

Product line strategy is common nowadays in companies. At first, almost all companies start with a short product line, and with passes of time, companies add different product lines to expand their business.

The main objective of adopting different product lines for companies is to retain existing customers and attract new ones. It helps to maintain the taste of customers as it aligns with the changes in the market and customers’ expectations.

Closely related products, sold under a specific brand, and sold to almost the same consumer groups are the three phrases that define the product lines.

According to Craven, Hills, & Woodruff – A product line is a group of products that are in some way related by being alternative to fulfilling the same consumers’ need, by being marketed to the same target markets, or through the same distribution network, or by being in the common price category.

Objectives of Product Line

The following are the main objectives companies aim to achieve by adopting a product line strategy.

  • Retain the existing customers.
  • Attract new customers.

Product Line Analysis

As a marketer, you should review the actual position of your company’s product line in relation to its profits and sales. You should also review the competitor’s position in the same market area.

This analysis will help you to decide whether your company should expand the line, improve the existing line, remain as it is, or reduce the product line.

Product Line Length

It refers to the total number of interrelated products a company produces. The general thinking is that the number of products a company produces should be optimal or manageable.

However, the company’s product line length decision is affected by its objectives. The company’s product lines usually tend to lengthen over time.

Line Modernization Decision

Despite the ideal product line length, not all of the items in the line may be beneficial. Some products could be less effective at bringing in customers and money for the business.

Under such a situation, you should consider modernizing such soft items by maintaining or improving their quality using modern technology, or other steps determined by the company.

Line Featuring Decision

Sometimes you may select one or a few items in the line to develop them as promotional or leader items, as it is not possible to modernize all the items in the line.

A business can improve its reputation in the market by showcasing a few products. This image will be useful to increase sales of other products that aren’t featured, resulting in acceptable sales and profits.

Line Pruning Decision

Some products in the line might lose the business money or cause problems. When a business decides that featuring or upgrading them won’t fix the issue, it may eliminate or remove such items from the line and keep the high-margin products. This decision is known as the line pruning decision.

When profits are reduced by extending the line’s products and when the company lacks the production capability to create each of the existing items, the company may decide to prune the line.

Examples of Product Line

You can see the example of product lines in every company that sells more than one product. Let’s look at some examples of product lines of different companies.

Product lines are the particular groups of products or brands a company sells. Such a line has products that are interrelated to each other and often targeted to the same markets.

On the other hand, a product mix includes all the products or product lines a company has in its offerings for its consumers.

The product lines come within the product mix. So, the product line is the subset of the product mix, whereas, the product mix is the superset of the product line.
