Product Life Cycle

The Product Life Cycle (PLC) is based upon the biological life cycle. For example, a seed is planted (introduction); it begins to sprout (growth); it shoots out leaves and puts down roots as it becomes an adult (maturity); after a long period as an adult the plant begins to shrink and die out (decline).

Decline.
At this point there is a downturn in the market. For example more innovative products are introduced or consumer tastes have changed. There is intense price-cutting and many more products are withdrawn from the market. Profits can be improved by reducing marketing spend and cost cutting.

Introduction Stage
In the introduction stage, the firm seeks to build product awareness and develop a market for the product. The impact on the marketing mix is as follows:

• Product branding and quality level is established, and intellectual property protection such as patents and trademarks are obtained.
• Pricing may be low penetration pricing to build market share rapidly, or high skim pricing to recover development costs.
• Distribution is selective until consumers show acceptance of the product.
• Promotion is aimed at innovators and early adopters. Marketing communications seeks to build product awareness and to educate potential consumers about the product.

Growth Stage
In the growth stage, the firm seeks to build brand preference and increase market share.

• Product quality is maintained and additional features and support services may be added.
• Pricing is maintained as the firm enjoys increasing demand with little competition.
• Distribution channels are added as demand increases and customers accept the product.
• Promotion is aimed at a broader audience.

Maturity Stage
At maturity, the strong growth in sales diminishes. Competition may appear with similar products. The primary objective at this point is to defend market share while maximizing profit.

• Product features may be enhanced to differentiate the product from that of competitors.
• Pricing may be lower because of the new competition.
• Distribution becomes more intensive and incentives may be offered to encourage preference over competing products.
• Promotion emphasizes product differentiation.

Decline Stage
As sales decline, the firm has several options: 

• Maintain the product, possibly rejuvenating it by adding new features and finding new uses.
• Harvest the product - reduce costs and continue to offer it, possibly to a loyal niche segment.
• Discontinue the product, liquidating remaining inventory or selling it to another firm that is willing to continue the product.

The marketing mix decisions in the decline phase will depend on the selected strategy. For example, the product may be changed if it is being rejuvenated, or left unchanged if it is being harvested or liquidated. The price may be maintained if the product is harvest, or reduced drastically if liquidated. 

Problems with Product Life Cycle.
In reality very few products follow such a prescriptive cycle. The length of each stage varies enormously. The decisions of marketers can change the stage, for example from maturity to decline by price-cutting. Not all products go through each stage. Some go from introduction to decline. It is not easy to tell which stage the product is in. Remember that PLC is like all other tools. Use it to inform your gut feeling.

Another marketing tool for evaluating Product is the Three Levels of a Product.

In theory it’s the same for a product. After a period of development it is introduced or launched into the market; it gains more and more customers as it grows; eventually the market stabilises and the product becomes mature; then after a period of time the product is overtaken by development and the introduction of superior competitors, it goes into decline and is eventually withdrawn.

However, most products fail in the introduction phase. Others have very cyclical maturity phases where declines see the product promoted to regain customers.
