6.4 Portfolio management and BCG matrix

Corporate strategy often involves managing a diverse set of businesses. Portfolio management helps companies analyze and optimize their business units for overall success. The BCG matrix is a key tool in this process, categorizing businesses based on market share and growth.

By using the BCG matrix, companies can make informed decisions about resource allocation and strategic direction. This approach allows firms to balance their portfolio, investing in high-potential areas while managing or divesting underperforming units to maximize overall value and competitiveness.

1 of 3

• Portfolio management analyzes and manages a company's collection of businesses or products as a whole to maximize overall performance and value
• Involves making strategic decisions about resource allocation, investment, divestment, and prioritization among the various businesses or products in the portfolio
• Main objectives of portfolio management:
  • Achieve synergy
  • Balance risk and return
  • Align the portfolio with the company's overall strategy and goals

Key Requirements and Tools

• Effective portfolio management requires a clear understanding of each business unit's:
  • Market position
  • Competitive advantages
  • Growth potential
  • Financial performance
• Tools and frameworks used in portfolio management:
  • BCG matrix
  • GE-McKinsey matrix
  • Product life cycle model

BCG Matrix Application

Matrix Structure and Quadrants

• The BCG (Boston Consulting Group) matrix categorizes business units or products into four quadrants based on their relative market share and market growth rate
• The four quadrants of the BCG matrix:
  • Stars: High market share in a high-growth market; require significant investment to maintain their position and have the potential to generate substantial profits (e.g., a leading smartphone brand in a rapidly growing market)
  • Cash Cows: High market share in a low-growth market; generate more cash than they consume and can be used to fund other business units (e.g., a dominant brand in a mature industry like soft drinks)
  • Question Marks: Low market share in a high-growth market; require significant investment to gain market share and have uncertain future prospects (e.g., a new product launch in an emerging market)
  • Dogs: Low market share in a low-growth market; may generate enough cash to sustain themselves but are not likely to be significant sources of growth or profitability (e.g., a declining product line in a shrinking market)

Application Process and Strategic Implications

• To apply the BCG matrix:
  • Define the relevant market
  • Measure each business unit's relative market share and market growth rate
  • Plot them on the matrix
• The position of a business unit on the BCG matrix suggests different strategic options:
  • Invest in Stars
  • Maintain Cash Cows
  • Divest or turn around Dogs
  • Selectively invest in Question Marks

Strategic Options for Portfolios

Investment, Maintenance, and Divestment Strategies

• Based on portfolio analysis using tools like the BCG matrix, a company can consider various strategic options for managing its business units:
  • Investment and growth: Allocate resources to high-potential business units (Stars and promising Question Marks) to capitalize on growth opportunities and increase market share
  • Maintenance and stability: Sustain the performance of mature, profitable business units (Cash Cows) to generate funds for investment in other areas
  • Divestment or turnaround: Sell, spin off, or restructure underperforming business units (Dogs and some Question Marks) to free up resources and improve overall portfolio performance

Portfolio Pruning, Rebalancing, and Synergy

• Portfolio pruning involves regularly reviewing the business portfolio and divesting units that no longer fit the company's strategic objectives or meet performance expectations
• Rebalancing the portfolio may be necessary to maintain a desired mix of growth, profitability, and risk, which can be achieved through:
  • Acquisitions
  • Divestitures
  • Internal development
• Synergy among business units can be leveraged by sharing resources, capabilities, or customer bases to create value and competitive advantage (e.g., cross-selling products or services, sharing technology or distribution channels)

Limitations of Portfolio Planning

Criticisms of Portfolio Planning Tools

• Portfolio planning tools, such as the BCG matrix, have several limitations and have faced criticisms:
  • Oversimplification: The tools reduce complex business realities to a few dimensions, which may not capture all relevant factors and nuances
  • Subjectivity: Defining market boundaries, measuring market share and growth, and categorizing business units can be subjective and may vary depending on the analyst
  • Static nature: The tools provide a snapshot of the portfolio at a given time, but market conditions and business unit positions can change rapidly
  • Focus on past performance: The tools rely heavily on historical data and may not adequately consider future trends, disruptive innovations, or shifting customer preferences
  • Lack of prescriptive detail: While the tools suggest general strategic directions, they do not provide specific guidance on how to implement those strategies

Potential Drawbacks and Considerations

• Critics argue that portfolio planning tools may lead to an overemphasis on short-term financial performance at the expense of long-term innovation and growth
• The tools may not adequately account for the value of intangible assets, such as brand equity, intellectual property, or human capital, which can be critical sources of competitive advantage
• Despite these limitations, portfolio planning tools can still be useful as part of a broader strategic analysis and decision-making process, when used in conjunction with other tools and qualitative judgment
