3.15 - Product Life Cycle & Extension Strategies
The purpose of product portfolio analysis
Product portfolio analysis involves evaluating a business's range of products to guide decisions on launching new items or refreshing existing ones. This process helps maintain competitiveness and profitability by identifying the right timing for changes.
Key techniques in product portfolio analysis
- Product life cycle - Tracks a product's sales performance over time, highlighting stages where intervention may be needed.
- Boston Matrix analysis - Assesses products based on market share and growth potential, often used alongside the product life cycle for deeper insights.
Failing to adapt products in response to competitors' innovations can lead to lost market share, making regular analysis essential for long-term success.
The stages of the product life cycle
The product life cycle describes how a product's sales evolve from launch to eventual withdrawal. Understanding these stages allows businesses to anticipate changes and plan accordingly.
Introduction
The product enters the market after development and testing. Sales start low as awareness builds, with high costs often outweighing revenue.
Growth
Sales rise rapidly due to successful marketing efforts. This phase may slow as rivals enter the market, technology advances, consumer preferences shift, or the market becomes saturated.
Maturity/saturation
Sales stabilise at a high level without major drops. This stage can persist for extended periods, especially for well-established products.
Decline
Sales fall steadily as newer alternatives from competitors emerge, making the product less viable or prompting its replacement.
Extension strategies to prolong product life
Extension strategies are actions taken to extend a product's profitable phase, delaying the need for a full replacement. These approaches help sustain sales during maturity or early decline.
Common extension strategies
- Entering new markets - Expanding to export markets or untapped domestic segments to reach fresh customers.
- Repackaging and relaunching - Updating the product's appearance or branding to refresh its appeal.
- Discovering new applications - Promoting alternative uses for the product to attract different user groups.
- Adding updates - Introducing new features, colours, or designs to modernise the product and meet evolving demands.
Marketing mix decisions across life cycle stages
The marketing mix, consisting of product, price, place, and promotion, must be adjusted at each life cycle stage to maximise sales and profitability.
| Stage | Product | Price | Place | Promotion |
|---|---|---|---|---|
| Introduction | Basic version to test market | High (skimming) or low (penetration) to build share | Limited outlets for exclusivity | Heavy focus on informing customers |
| Growth | Improvements based on feedback | Possible increases as demand grows | Wider distribution to meet demand | Build brand loyalty through advertising |
| Maturity | Variations to differentiate | Competitive to retain market share | Maximum reach across channels | Emphasise unique benefits |
| Decline | Minimal changes or withdrawal | Reduced to sell stock (or premium for niches) | Cut unprofitable outlets | Low-level or none to minimise costs |
These adaptations ensure the marketing approach aligns with the product's current position, supporting sustained performance.
Benefits and limitations of a balanced product portfolio
A balanced product portfolio involves maintaining products at various life cycle stages simultaneously. This strategy provides stability but has drawbacks that businesses must consider.
Advantages of a balanced portfolio
- Steady cash flow - Revenue from mature products can fund the development and launch of new ones.
- Efficient resource use - Keeps production facilities running at consistent levels, avoiding underutilisation.
- Preparedness for change - Ensures successor products are available as older ones enter decline, reducing gaps in offerings.
Limitations of product life cycle analysis for portfolio management
- Predictive challenges - Relies on historical and current data, which may not accurately forecast future trends.
- Unexpected shifts - Some products decline rapidly, leaving no opportunity for extensions, while others, like fashion items (e.g., oversized sunglasses or low-rise jeans), may fade and then revive unpredictably.
- Variable outcomes - Certain products experience ongoing growth contrary to expectations.
- Need for integration - Works best when combined with tools like Boston Matrix analysis, sales projections, and managerial expertise to enhance reliability.
