Summary of Arthur D. Little Matrix: Portfolio Analysis
Arthur D. Little Matrix: Comprehensive Portfolio Analysis Guide
Introduction
Corporate Portfolio Analysis is a structured approach for evaluating a company's collection of Business Units (BUs) to decide where to invest, harvest, divest or liquidate. It assesses three core dimensions: future growth potential, potential profitability, and investment needs. The goal is to produce a balanced portfolio aligned with corporate strategy and financial viability.
Definition: Corporate Portfolio Analysis — a systematic evaluation of a firm's Business Units to inform corporate-level allocation of resources and strategic decisions.
Overview of the ADL / PAT approach
The ADL (Arthur D. Little) matrices and the PAT (Portfolio Analysis Technique) process break the portfolio diagnosis into three differentiated matrices that reflect the three core dimensions:
- ADL – Sales matrix: focuses on future growth potential using sales distribution by industry life cycle stage.
- ADL – Economic profitability matrix: evaluates potential profitability and capability for generating future income.
- ADL – Asset matrix: estimates potential future investment needs.
These matrices combine to support the PAT Analysis, which proceeds in clear stages.
Main stages in PAT Analysis
- Strategic segmentation and starting point situation for each Business Unit (and synergies among them).
- Analysis of each Business Unit for representation in the portfolio.
- Diagnosis of the corporation's situation to assess portfolio balance: future growth potential, future profitability, and financial viability.
- Decision-making on corporate and competitive strategy.
Step 1 — Strategic segmentation and starting situation
What to document
- Presentation of Business Units
- Are BUs clearly differentiated? Distinct products or sectors?
- Do they share synergies (technology, channels, supply chain)?
- General financial figures
- Return on Investment (ROI), Profit Margin, Asset Turnover, Return on Equity (ROE), Financial Expenses, Leverage
- Type of diversification
- Related or unrelated diversification and the degree of synergy among BUs
Definition: Strategic segmentation — the process of grouping a corporation’s activities into separate Business Units for targeted analysis and strategy.
Step 2 — Analysis of each Business Unit
For each BU, assess the following and place the BU in the chosen matrix dimensions (ADL and/or McKinsey-style where applicable).
Key assessment elements:
- Competitive position (ADL categories: Dominant, Strong, Favourable, Weak, Marginal)
- Consider relative market share and business profitability vs. sector average
- Industry life cycle stage (Introduction, Growth, Maturity, Decline)
- Sector attractiveness (e.g., market size, growth rate, structural profit potential)
Practical format (Table-style guidance):
| Business Unit | Competitive position (ADL / McKinsey) | Industry life cycle stage | Attractiveness (McKinsey) |
|---|---|---|---|
| BU 1 | Analysis - Conclusion (Dominant/High/etc.) | Analysis - Conclusion (Introduction/Growth/Maturity/Decline) | Analysis - Conclusion (High/Medium/Low) |
| BU 2 | ... | ... | ... |
Definition: Competitive position — a summary measure of a BU’s strength in its market based on market share, profitability and other competitive advantages.
How to assess competitive position (ADL criteria)
Consider these factors:
- Relative market share: the BU’s share compared to the largest competitor or the market leader.
- Business profitability vs sector average: margins, ROA, ROE relative to peers.
Guidelines:
- Dominant: clear market leader with superior profitability.
- Strong: above-average share and profitability.
- Favourable: adequate position with growth potential.
- Weak: below-average share or profitability needing defensive action.
- Marginal: small positions or consistently unprofitable — candidate for divestment.
