Product Life Cycle

Product Life Cycle (PLC) The idea of the Product Life Cycle was first developed in 1965 by Theodore Levitt in an article entitled “Exploit the Product Life Cycle” published in the Harvard Business Review on 1 November 1965. For a business, having a growing and sustainable revenue stream from product sales is important for the stability and success of its operations. The Product Life Cycle model can be used by consultants and managers to analyse the maturity stage of products and industries. Understanding which stage a product is in provides information about expected future sales growth, and the kinds of strategies that should be implemented.

Product Life Cycle model: The “Product Life Cycle” is the name given to the stages through which a product passes over time. The classic Product Life Cycle has four stages: 1} Market introduction stage. 2} Growth stage. 3} Mature stage. 4} Saturation and decline stage
1 Market introduction stage At the market introduction stage the size of the market, sales volumes and sales growth are small. A product will also normally be subject to little or no competition. The primary goal in the introduction stage is to establish a market and build consumer demand for the product. There may be substantial research and development costs incurred in getting a product to the market introduction stage, for example, thinking of the product idea, developing the technology, determining the product features and quality level, establishing sufficient manufacturing capacity, preparing the product branding, ensuring trade mark protection, etc. Marketing costs may be high in order to test the market, launch and promote the product, develop a market for the product, and set up distribution channels. The market introduction stage is likely to be a period of low or negative profits. As such, it is important that products are carefully monitored to ensure that sales volumes start to grow. If a product fails to become profitable it may need to be abandoned.

Some of the considerations in the introduction stage include:
Product development: research and development of the basic technology and product concept, determining the product features and quality level.
Pricing: should penetration pricing or a skimming price strategy be used? A skimming price strategy might be appropriate where there are very few competitors.
Distribution: distribution might be quite selective until consumer acceptance of the product can be achieved.
Promotion: marketing efforts are aimed at early adopters, and seek to build product awareness and to educate potential consumers about the product.
Features: - 1. Costs are high 2. Slow sales volumes to start 3. Little or no competition - competitive manufacturers watch for acceptance/segment growth losses 4. Demand has to be created 5. Customers have to be prompted to try the product 6. Makes no money at this stage
2 Growth Stage If the public gains awareness of a product and consumers come to understand the benefits of the product and accept it then a company can expect a period of rapid sales growth, enter the “Growth Stage”. In the Growth Stage, a company will try to build brand loyalty and increase market share. Profits are driven by increased sales volume (due to growth in market share as well as an increase in the size of the overall market). Profits might also be driven by cost reductions gained from economies of scale, and perhaps more favourable market prices. Competition in the Growth Stage remains low, although new competitors are expected to enter the market. When competitors enter the market a company might be subject to price competition and increase its marketing expenditure.

Some of the considerations in the Growth Stage include:
Product improvement: product quality might be improved, additional features and support services added, and packaging updated.
Pricing: if consumer demand is high the price might be maintained at a high level.
Distribution: distribution channels might be added as consumer demand increases.
Promotion: promotion is aimed at a broader audience. A company might spend a lot of resources on promotion during the Growth Stage to build brand loyalty.
Features: - 1. Costs reduced due to economies of scale 2. Sales volume increases significantly 3. Profitability begins to rise 4. Public awareness increases 5. Competition begins to increase with a few new players in establishing market 6. Increased competition leads to price decreases
3 Maturity Stage When a product reaches maturity, sales growth slows and sales volume eventually peaks and stabilises. This is the stage during which the market as a whole makes the most profit. A company’s primary objective at this point is to defend market share while maximising profit. In this stage, prices tend to drop due to increased competition. A company’s fixed costs are low because it is has well established production and distribution. Since brand awareness is strong, marketing expenditure might be reduced, although increased marketing expenditure might be needed to retain market share and fight increasing competition. Expenditure on research and development is likely to be restricted to product modification and improvement, and perhaps research into improved production efficiency and product quality.

Some considerations for the mature product market include:
Product differentiation: increased competition in the mature product market means that a company must find ways to differentiate its product from that of competitors. Strong branding is one way to do this.
Pricing: prices may be reduced because of increased competition. Firms in the market should be careful not to start a price war.
Distribution: distribution intensifies and incentives may be offered to encourage preference to be given over competing products.
Promotion: promotion will focus on emphasising product differences and creating/maintaining a strong brand.
Features: - 1. Costs are lowered as a result of production volumes increasing and experience curve effects 2. Sales volume peaks and market saturation is reached 3. Increase in competitors entering the market 4. Prices tend to drop due to the proliferation of competing products 5. Brand differentiation and feature diversification is emphasized to maintain or increase market share 6. Industrial profits go down
4 Saturation and decline stage A product enters into decline when sales and profits start to fall. The market for that product shrinks which reduces the amount of profit available to the firms in the industry. A decline might occur because the market has become saturated, the product has become obsolete, or customer tastes have changed. A company might try to stimulate growth by changing their pricing strategy, but ultimately the product will have to be re-designed, or replaced. High-cost and low market share firms will be forced to exit the industry.
As sales decline, a company has three strategy options: · Hold: maintain production and add new features and find new uses for the product. Reduce the cost of manufacturing (e.g. move manufacturing to a low cost jurisdiction). Consider whether there are new markets in which the product might be sold. · Harvest: continue to offer the product, reduce marketing expenditure, and sell possibly to a loyal niche segment of the market. · Divest: Discontinue production, and liquidate the remaining inventory or sell the product to another firm.
Some considerations for a declining market include:
Product consolidation: the number of products may be reduced, and surviving products rejuvenated.
Price: prices may be lowered to liquidate inventory, or maintained for continued products.
Distribution: distribution becomes more selective. Channels that are no longer profitable are asked out.
Promotion: Expenditure on promotion is reduced for products subject to the Harvest and Divest strategies.
Features: - 1. Costs become counter-optimal 2. Sales volume decline or stabilize 3. Prices, profitability diminish 4. Profit becomes more a challenge of production/distribution efficiency than increased sales.
It is claimed that every product has a life cycle. It is launched; it grows, and at some point, may die. A fair comment is that - at least in the short term - not all products or services die. Jeans may die, but clothes probably will not. Legal services or medical services may die, but depending on the social and political climate, probably will not. Even though its validity is questionable, it can offer a useful 'model' for managers to keep at the back of their mind. Indeed, if their products are in the introductory or growth phases, or in that of decline, it perhaps should be at the front of their mind; for the predominant features of these phases may be those revolving around such life and death. Between these two extremes, it is salutary for them to have that vision of mortality in front of them. However, the most important aspect of product life-cycles is that, even under normal conditions, to all practical intents and purposes they often do not exist (hence, there needs to be more emphasis on model/reality mappings). In most markets the majority of the major brands have held their position for at least two decades. The dominant product life-cycle, that of the brand leaders which almost monopolize many markets, is therefore one of continuity. In the criticism of the product life cycle, Dhalla & Yuspeh state: ...clearly, the PLC is a dependent variable which is determined by market actions; it is not an independent variable to which companies should adapt their marketing programs. Marketing management itself can alter the shape and duration of a brand's life cycle. Thus, the life cycle may be useful as a description, but not as a predictor; and usually should be firmly under the control of the marketer. The important point is that in many markets the product or brand life cycle is significantly longer than the planning cycle of the organisations involved. Thus, it offers little practical value for most marketers.
