## Portfolio Analysis Tools
Portfolio analysis tools help organizations decide how to allocate resources across their portfolio of Strategic Business Units (SBUs) or products.

## A. BCG (Boston Consulting Group) Growth-Share Matrix
Purpose: The simplest way to portray a corporation's portfolio of investments.
Two Dimensions: Market Growth Rate (vertical) × Relative Market Share (horizontal)
### Four Categories of SBUs/Products
| Category | Market Growth | Market Share | Key Characteristic | Recommended Strategy |
|---|---|---|---|---|
| Stars | High | High | Growing rapidly; need heavy investment; best expansion opportunities | Hold — preserve market share |
| Cash Cows | Low | High | Generate cash, low costs; mature stars become cash cows | Harvest — maximize short-term cash flow |
| Question Marks | High | Low | Need heavy investment; low cash generation; can become Stars or Cash Traps if neglected | Build — increase market share |
| Dogs | Low | Low | Minimal future; may barely survive | Divest — sell or liquidate; resources better used elsewhere |
### Post-Identification Strategies
1. Build (Question Marks): Increase market share even by forgoing short-term earnings
2. Hold (Stars): Preserve market share
3. Harvest (Cash Cows): Increase short-term cash flow regardless of long-term effect
4. Divest (Dogs): Sell or liquidate the business
### Limitations of BCG Matrix
1. Difficult, time-consuming, and costly to implement; hard to define SBUs and measure market share/growth
2. Provides little advice for future planning
3. Overemphasis on market-share growth → unwise expansion into risky ventures OR premature divestment of established units

## C. ADL (Arthur D. Little) Matrix
Purpose: Portfolio analysis technique based on the Product Life Cycle (PLC).
Two Dimensions: Stage of Industry Maturity (PLC) × Firm's Competitive Position
### Competitive Position Classifications
1. Dominant: Rare — monopoly or strong protected technological leadership
2. Strong: Choice of strategies; not unduly threatened by competition
3. Favorable: Fragmented industry; no one competitor stands out clearly; reasonable freedom
4. Tenable: Satisfactory performance but vulnerable with increased competition
5. Weak: Unsatisfactory performance though opportunities for improvement exist
### ADL Matrix Structure
| Competitive Position | Embryonic | Growth | Mature | Ageing |
|---|---|---|---|---|
| Dominant | ||||
| Strong | ||||
| Favorable | ||||
| Tenable | ||||
| Weak |
