The Introduction Stage is characterized by slow sales growth and high costs due to heavy promotion and distribution expenses. The primary goal here is to create product awareness and induce trial among early adopters.
During the Growth Stage, sales rise rapidly as more consumers become aware of the product and competitors begin to enter the market. Companies focus on building brand loyalty and expanding distribution channels to capture market share.
The Maturity Stage sees a slowdown in sales growth as the product has achieved acceptance by most potential buyers. Competition becomes intense, leading to price wars and a focus on product modification or finding new market segments to maintain profitability.
In the Decline Stage, sales drop significantly due to technological advances, shifts in consumer tastes, or increased competition. Management must decide whether to maintain the brand, harvest it by reducing costs, or drop it from the product line entirely.
The Product Mix Width refers to the number of different product lines a company carries. A wide mix can help a company diversify its risk across different market segments.
The Product Mix Length is the total number of items the company carries within its product lines. Increasing length can help a company satisfy different price points or specific consumer niches.
The Product Mix Depth refers to the number of versions offered of each product in the line, such as different sizes, flavors, or formulations. Deep lines allow for precise targeting of specific consumer preferences.
Consistency describes how closely related the various product lines are in terms of end-use, production requirements, or distribution channels. High consistency allows a firm to leverage its core competencies across its entire portfolio.
| Feature | Physical Goods | Services |
|---|---|---|
| Tangibility | Tangible; can be seen and touched. | Intangible; cannot be held or stored. |
| Separability | Produced and consumed separately. | Produced and consumed simultaneously. |
| Perishability | Can be stored in inventory for later. | Cannot be stored; lost if not used. |
| Variability | Standardized through manufacturing. | Highly variable based on the provider. |
Because services are intangible, marketers must 'tangibilize' the service by providing physical cues of quality, such as professional environments or certifications.
The perishability of services means that capacity management is critical; for example, an empty airline seat represents revenue that can never be recovered once the flight departs.
Identify the Level: When asked about product strategy, always distinguish between the core benefit and the augmented features. Many exam questions test whether you can identify that a 'warranty' is part of the augmented product, not the actual product.
PLC Strategy Alignment: Ensure your recommended marketing tactics match the specific stage of the Product Life Cycle. For example, recommending 'price skimming' is common in the introduction stage, while 'price matching' is more typical of the maturity stage.
Classification Logic: Use the consumer's buying behavior (effort, frequency, comparison) to classify products rather than the physical nature of the item itself. A computer could be a shopping good for a student but a specialty good for a professional designer.
Check for Consistency: When analyzing a product mix, evaluate if the new product fits the company's existing distribution and production capabilities. Inconsistent product lines often lead to brand dilution and operational inefficiencies.
