Product Life Cycle

The Four Stages

1. Introduction

  • Product launched on the market
  • Sales grow slowly — awareness is low
  • High costs — R&D, advertising, launch
  • Usually making a loss
  • Skimming or penetration pricing used

2. Growth

  • Sales rise rapidly
  • Brand awareness increases
  • Competitors begin to enter the market
  • Profits start to be made
  • Business invests in capacity to meet demand

3. Maturity

  • Sales peak — market is saturated
  • Profits highest — costs are under control
  • Heavy competition — price wars possible
  • Extension strategies needed to prolong this stage

4. Decline

  • Sales fall — replaced by newer products
  • Profits shrink; may go negative
  • Business decides to withdraw or use extension strategy
  • Costs cut — marketing reduced
Extending the Life Cycle

Extension Strategies

Definition

Extension strategies are used during maturity or early decline to extend the life of a product and delay its withdrawal from the market.

Product Differentiation

USP & Branding

USP (Unique Selling Point)

  • What makes a product different and better than competitors
  • Can be: quality, price, design, features, sustainability, service
  • Allows a business to charge higher prices
  • Reduces price competition — customers buy for the USP, not just price
  • Example: Apple's USP = premium design + ecosystem lock-in

Branding

  • A brand is more than a logo — it's the feelings customers associate with a business
  • Strong brands command premium prices and loyalty
  • Reduces marketing costs — brand does the selling
  • Hard to build but very valuable (brand equity)
  • Example: Nike's "swoosh" and "Just Do It" create instant recognition
Portfolio Management

The Boston Matrix

What is it?

The Boston Matrix classifies a business's product portfolio by market share (horizontal axis) and market growth (vertical axis) into four quadrants.

⭐ Stars

High market share, high growth

❓ Question Marks

Low market share, high growth

🐄 Cash Cows

High market share, low growth

🐕 Dogs

Low market share, low growth

← Low market share | High market share →
The Four Quadrants

Stars, Cash Cows, Question Marks, Dogs

⭐ Stars

  • High growth, high market share
  • Great potential — invest heavily
  • High revenue but also high costs
  • Likely future Cash Cows

❓ Question Marks

  • High growth, low market share
  • High potential but uncertain future
  • Need investment to become Stars
  • May become Dogs if market share doesn't grow

🐄 Cash Cows

  • Low growth, high market share
  • Steady profit — market is mature
  • Low investment needed
  • Profits fund Stars and Question Marks

🐕 Dogs

  • Low growth, low market share
  • Usually loss-making or breaking even
  • Consider withdrawing from market
  • May be kept if they serve a niche or customer loyalty
Strategic Tool

Using the Boston Matrix

Practice Question 1 of 3

A soft drink launched 5 years ago now has the highest sales in a stagnant market. Production costs are low and it generates strong profit. Where does it sit in the Boston Matrix?

AStar — high market share, high market growth
BCash Cow — high market share, low market growth
CQuestion Mark — low market share, high market growth
DDog — low market share, low market growth
Correct: B. The product has high market share (highest sales) in a stagnant (low growth) market — this is the definition of a Cash Cow. Cash Cows are mature, established products that generate steady profit with minimal investment. Their profits are used to fund Stars and Question Marks in the portfolio.
Practice Question 2 of 3

A chocolate brand's best-selling bar has been on sale for 30 years. Sales are starting to fall as healthier alternatives gain popularity. The company introduces a 'dark chocolate' variant and promotes it on social media. This is an example of:

AAn extension strategy to prolong the product life cycle
BWithdrawing the product from the market
CLaunching a completely new product
DUsing penetration pricing to boost revenue
Correct: A. Introducing a new variant (dark chocolate) and promoting it via social media are extension strategies. They aim to revive interest in a product that is entering decline, extend its life cycle, and attract new customers. This is different from launching a wholly new product — it is a modification of the existing brand.
Practice Question 3 of 3

A tech company has a new app that operates in a fast-growing market but currently has only 3% market share. Using the Boston Matrix, this app is best classified as a:

ACash Cow — profitable and established
BStar — leading the high-growth market
CQuestion Mark — high growth, low market share; uncertain future
DDog — low growth, low market share
Correct: C. The app is in a high-growth market (fast-growing) but has low market share (3%). This matches the Question Mark quadrant. Question Marks have potential but an uncertain future — they need investment to grow market share and become Stars. Without sufficient investment, they risk becoming Dogs as the market matures.
