Summary of Corporate Strategy and Business Growth
Corporate Strategy and Business Growth: Student's Guide
Introduction
Portfolio analysis examines a company's mix of business units or products to determine which components to invest in, hold, harvest, or divest. The techniques help managers assess maturity, attractiveness, growth potential, and the expected contribution of each activity to corporate profitability and financial balance.
Portfolio analysis: A set of tools to evaluate and visualise the relative position of business units using strategic and financial variables to guide resource allocation decisions.
Why portfolio analysis matters
- Identifies which business units drive growth and profitability
- Reveals corporate balance or imbalance among activities
- Supports prioritising investment and divestment decisions
Common features of portfolio techniques
- All require segmentation of the product/business portfolio
- They use two axes (X and Y) representing internal and external variables
- Axes are divided into quadrants (commonly 4 or 9) to derive specific strategy recommendations
- Businesses are plotted graphically; circle size often represents relative importance (e.g., revenue)
Key variables used
- Internal variables (examples): relative market share, competitive position, cost structure, capabilities
- External variables (examples): market growth rate, industry attractiveness, life-cycle stage
- Typical goal: detect which business units contribute to growth and long-term financial equilibrium
Main portfolio analysis techniques
| Technique | Axis OX | Axis OY |
|---|---|---|
| Boston Consulting Group (BCG) Matrix | Relative market share (internal) | % Market growth (external) |
| Arthur D. Little (ADL) Matrix | Industry life-cycle stage (external) | Competitive position (internal) |
| McKinsey (GE) Matrix | Competitive position (internal) | Industry attractiveness (external) |
Did you know that portfolio matrices often display business units as circles whose area represents size (for example, sales or profit)?
1. Boston Consulting Group (BCG) Matrix
The BCG Matrix classifies business units by market growth (external) and relative market share (internal). It helps set priorities and resource allocation strategies.
BCG Matrix: A 2x2 portfolio tool that groups units into Stars, Cash Cows, Question Marks, and Dogs based on growth and market share.
Quadrants and recommended objectives:
- Stars: High market growth, high relative market share
- Priority: Invest to consolidate leadership and support continued growth
- Cash Cows: Low market growth, high relative market share
- Priority: Maintain market leadership and harvest cash to fund other units
- Question Marks: High market growth, low relative market share
- Priority: Selectively invest to improve position or change strategy
- Dead Weight (Dogs): Low market growth, low relative market share
- Priority: Attempt improvement only if feasible; otherwise divest or liquidate
Pros:
- Forecasting-oriented: anticipates future resource needs if trends persist
- Clarifies investment priorities and corporate financial equilibrium
- Simple and operational
Cons:
- Assumes stability of market share and growth rates; not suited to highly volatile contexts
- Equates market share with competitive advantage and profitability, which may be invalid if no scale/experience effects exist
- Less useful where differentiation, not volume, drives competition
- Does not prescribe competitive actions
Practical example:
- A consumer-electronics firm may classify its flagship smartphone line as a Star, a legacy TV line as a Cash Cow, a new wearable as a Question Mark, and an outdated MP3 player as a Dead Weight.
2. Arthur D. Little (ADL) Matrix
The ADL Matrix uses industry life-cycle stage (external) and competitive position (internal). It is more dynamic and multidimensional than BCG.
ADL Matrix: A grid combining industry life-cycle stages with competitive strength to provide tailored strategic recommendations.
Pros:
- Adapts better to sp

Klíčové pojmy: Portfolio analysis evaluates business units to guide resource allocation, BCG uses relative market share and market growth to classify units into Stars, Cash Cows, Question Marks, and Dogs, BCG pros: forecasting and simple prioritisation; cons: assumes stability and equates share with profitability, ADL Matrix uses industry life-cycle and competitive position for a more dynamic analysis, McKinsey Matrix evaluates industry attractiveness and competitive strength using multiple factors, Assess attractiveness by weighting factors that sum to $100$ and rating units on a $1$–$10$ scale, Portfolio tools are diagnostic and must be complemented with in-depth competitive and financial analysis, Use portfolio outcomes to decide invest, hold, harvest, or divest strategies
