11.8 The Product Life Cycle

Stages of the Life Cycle

As illustrated in Exhibit 11.7, the product life cycle consists of the following stages:

1. Introduction: When a product enters the life cycle, it faces many obstacles. Although competition may be light, the introductory stage usually features frequent product modifications, limited distribution, and heavy promotion. The failure rate is high. Production and marketing costs are also high, and sales volume is low. Hence, profits are usually small or negative.

2. Growth: If a product survives the introductory stage, it advances to the growth stage of the life cycle. In this stage, sales grow at an increasing rate, profits are healthy, and many competitors enter the market. Large companies may start to acquire small pioneering firms that have reached this stage. Emphasis switches from primary demand promotion to aggressive brand advertising and communicating the differences between brands. For example, the goal changes from convincing people to buy flat-screen TVs to convincing them to buy Sony versus Panasonic or Sharp.

   Distribution becomes a major key to success during the growth stage, as well as in later stages. Manufacturers scramble to acquire dealers and distributors and to build long-term relationships. Without adequate distribution, it is impossible to establish a strong market position.

   Toward the end of the growth phase, prices normally begin falling, and profits peak. Price reductions result from increased competition and from cost reductions from producing larger quantities of items (economies of scale). Also, most firms have recovered their development costs by now, and their priority is in increasing or retaining market share and enhancing profits.

3. Maturity: After the growth stage, sales continue to mount—but at a decreasing rate. This is the maturity stage. Most products that have been on the market for a long time are in this stage. Thus, most marketing strategies are designed for mature products. One such strategy is to bring out several variations of a basic product (line extension). Kool-Aid, for instance, was originally offered in six flavors. Today there are more than 50, as well as sweetened and unsweetened varieties.

4. Decline (and death): When sales and profits fall, the product has reached the decline stage. The rate of decline is governed by two factors: the rate of change in consumer tastes and the rate at which new products enter the market. Sony VCRs are an example of a product in the decline stage. The demand for VCRs has now been surpassed by the demand for DVDs and online streaming of content. Sometimes companies can improve a product by implementing changes to the product, such as new ingredients or new services. If the changes are accepted by customers, it can lead to a product moving out of the decline stage and back into the introduction stage.

While some of these new beverages are close relatives of the original Coca-Cola Classic, others, such as Vitaminwater, constitute entirely new categories of soft drink.

The Product Life Cycle as a Management Tool

The product life cycle may be used in planning. Marketers who understand the cycle concept are better able to forecast future sales and plan new marketing strategies. Table 11.5 is a brief summary of strategic needs at various stages of the product life cycle. Marketers must be sure that a product has moved from one stage to the next before changing its marketing strategy. A temporary sales decline should not be interpreted as a sign that the product is dying. Pulling back marketing support can become a self-fulfilling prophecy that brings about the early death of a healthy product.
