## BCG Growth-Share Matrix

Developed by the Boston Consulting Group (BCG) in the early 1970s, the matrix helps companies manage a portfolio of Strategic Business Units (SBUs) or product lines by classifying them on two dimensions.

### Matrix Axes

Vertical axis: Market Growth Rate → measures market attractiveness
Horizontal axis: Relative Market Share → measures company strength

### Four Quadrants

Quadrant	Market Share	Growth Rate	Cash Flow	Strategy
Stars	High	High	Cash neutral (heavy investment needed)	Invest — best expansion opportunities
Cash Cows	High	Low	Strong cash generator	Hold/Harvest — minimal investment needed
Question Marks	Low	High	Cash drain	Build or Divest — heavy investment with uncertain returns
Dogs	Low	Low	Break-even or cash drain	Minimise via Divestment or Liquidation

### Strategic Choices

1. Build — Invest for long-term growth (Stars, selected Question Marks)

2. Hold — Preserve existing market share (Cash Cows facing competition)

3. Harvest — Maximise short-term cash flows

4. Divest — Sell/liquidate for better resource utilisation (Dogs)

### Product Life Cycle Progression in BCG

$$\text{Question Mark} \rightarrow \text{Star} \rightarrow \text{Cash Cow} \rightarrow \text{Dog}$$

As market growth slows, Stars with retained high share become Cash Cows.

Worked example

### Example 1

Soorya Ltd. Numerical (Chapter 4 Q41): The industry has only two firms — Soorya Ltd. and Chandra Ltd.

Product	Market Share	Industry Growth Rate	BCG Classification	Rationale
A	80%	+15%	Star	High share + high growth
B	40%	+10%	Question Mark	Low share + high growth
C	60%	−20%	Cash Cow	High share + negative growth
D	5%	−10%	Dog	Low share + negative growth

Soorya should invest in Product A (Star), harvest from Product C (Cash Cow), evaluate Product B (Question Mark), and consider divesting Product D (Dog).

### Example 2

Fashion Division of SCC (MTP1 May 2021): The Fashion division has high market growth AND is predicted to be market leader with ~10% share in a growing market. Both conditions — high growth + high relative market share — classify it as a Star.

### Example 3

Baba Pvt Ltd (MTP1 Nov 2021): Baba leased out nine of its seventeen factories, generating large surplus cash inflows, which it invests in financial assets. This is a Harvest strategy — the firm is maximising cash extraction from existing capacity rather than reinvesting for market growth.

⚠️ Common exam mistakes

Confusing Stars and Question Marks — both have HIGH growth rate, but Stars have HIGH market share and Question Marks have LOW market share
Confusing Cash Cows and Dogs — both have LOW growth rate, but Cash Cows have HIGH market share and Dogs have LOW market share
Thinking Dogs must always be immediately liquidated — Dogs 'may generate enough cash to maintain themselves'; the strategy is to minimise, not necessarily to liquidate immediately
Incorrectly stating that BCG assumes all products will grow and mature indefinitely — this is a false statement (a standard MCQ trap)
Forgetting that Stars eventually become Cash Cows as market growth rate slows — the life-cycle progression is a core BCG insight
