Porter’s Diamond Model is a diamond-shaped framework that explains why specific industries in a nation become internationally competitive while those in other nations do not. The model was first published in Michael Porter’s 1990 book The Competitive Advantage of Nations. This framework looks at the firm strategy, structure/rivalry, factor conditions, demand conditions, and related and supporting industries.
| Component | Description |
|---|---|
| Origin | Developed by Harvard Business School professor Michael E. Porter in 1990. |
| Overview | Porter’s Diamond Model, also known as the Diamond Theory of National Advantage, provides a framework for understanding why some countries or regions have a competitive advantage in certain industries. It identifies factors that contribute to a nation’s or region’s competitiveness on a global scale. |
| Key Elements | – Factor Conditions: Refers to a nation’s or region’s endowments in terms of labor, natural resources, capital, infrastructure, and technological capabilities. |
| – Demand Conditions: Describes the nature and size of the domestic or local market, including customer preferences, needs, and the level of sophistication. | |
| – Related and Supporting Industries: Focuses on the presence and strength of supporting industries, suppliers, and a competitive supply chain. | |
| – Firm Strategy, Structure, and Rivalry: Addresses the competitive dynamics within the nation or region, including the level of competition, management practices, and the overall business environment. | |
| How It Works | The Diamond Model emphasizes that these four interconnected elements influence one another and collectively impact a nation’s or region’s competitiveness in specific industries. Changes or improvements in one element can lead to ripple effects throughout the model, ultimately enhancing or diminishing competitiveness. |
| Applications | – Economic Policy: Used by governments to formulate policies that promote industry competitiveness. |
| – Investment Decisions: Helps businesses make informed decisions about where to invest and expand. | |
| Benefits | – Strategic Insight: Offers insights into factors affecting competitiveness in specific industries. |
| – Policy Guidance: Assists policymakers in shaping strategies to support national or regional industries. | |
| Drawbacks | – Complexity: Analyzing and managing all four factors can be intricate and may require extensive data and resources. |
| – External Factors: The model doesn’t account for external factors like global economic shifts or political changes. | |
| Key Takeaway | Porter’s Diamond Model emphasizes that competitiveness isn’t solely determined by one factor but results from the interplay of multiple elements. Nations or regions can enhance their competitive advantage by improving factor conditions, nurturing domestic demand, strengthening supporting industries, and fostering a competitive business environment. The model helps governments and businesses make informed decisions to enhance competitiveness. |
Understanding Porter’s Diamond Model
Traditional economic theory suggests that factors such as land, labor, population size, and natural resources are crucial factors in a nation gaining a competitive advantage.
However, Michael Porter argued that this model was a rather passive summary of economic potential and that far from creating sustained growth, the aforementioned factors may undermine any potential competitive advantage.
Instead, he proposed that four other characteristics could accurately predict whether a nation produced organizations that were competitive on the international stage.
These four characteristics give Porter’s model the diamond shape for which it is known, and they are explained in the next section.
The four characteristics of Porter’s Diamond Model
1. Firm Strategy, Structure, and Rivalry
This characteristic encompasses how companies are structured and managed.
It also includes company objectives and the presence of competitive rivalries, if applicable.
Rivalry is particularly important because it forces companies to innovate, better preparing them for the international market.
German auto manufacturers BMW, Mercedes-Benz, and Audi would not have become globally successful brands without the intense competition they face inside their native Germany.
2. Factor conditions
Factor conditions are more basic and refer to unskilled labor, natural resources, and infrastructure.
However, Porter argued that more advanced factor conditions such as skilled and specialist knowledge and access to capital were more important to competitive advantage.
3. Demand conditions
Demand conditions refer to the level of demand in the home market of industry.
Demand creates competition and in turn, competition creates innovation.
Specific demand conditions may include market size and market sophistication.
4. Related and supporting industries
Most large companies are only as successful as their supply chains.
Indeed, most are dependent on alliances and good relationships with suppliers to make cost savings that can be passed to consumers.
Nations with high concentrations of large, innovative companies that operate close to each other facilitate the spread of innovation.
For example, the cluster of tech companies in Silicon Valley, California, facilitates innovation because of the proximity of innovative and often supportive companies.
Criticisms of Porter’s Diamond Model
Given that Porter’s Model assesses competition in the relatively broad context of nations, it has been subject to criticism.
Criticisms include:
- Scope – when the model was developed in 1990, it included just 10 developed countries. As a result, it has limited relevance to second or third-world nations.
- Contradictory evidence – there is a wealth of evidence to suggest that the competitiveness of a nation has many external influences that Porter does not account for.
- Industry selective – Porter’s original analysis focused on the banking sector, consultancy firms, and manufacturers. Some academics have questioned whether the model is at all relevant to the many large and influential global service companies such as McDonald’s.
Drawbacks of Porter’s Diamond Model
Limited Scope and Generalization:
- Focus on Developed Economies: Porter’s Diamond Model is often criticized for being more applicable to advanced industrial economies and less relevant to developing countries.
- Generalization Issues: The model may oversimplify or generalize complex economic realities, potentially leading to incorrect or overly broad conclusions about a nation’s competitive advantage.
Overemphasis on Home Country:
- Neglects Global Influences: The model primarily focuses on the home country’s conditions, potentially neglecting the role of international markets and global economic dynamics.
- Underestimation of Multinational Corporations: It might underestimate the impact and influence of multinational corporations in shaping industries and competitive advantage.
Static Analysis:
- Lack of Dynamic Analysis: Porter’s Diamond Model is often seen as static, not adequately accounting for changes over time in economies or industries.
- Does Not Account for Evolution: The model does not explicitly address how national advantages can evolve or diminish over time.
Methodological Issues:
- Difficult to Quantify: Some aspects of the model, like firm strategy or rivalry, are qualitative and can be difficult to measure and compare across different countries or industries.
- Complex Interrelationships: The interrelationships between the different parts of the diamond are complex and can be challenging to analyze accurately.
When to Use Porter’s Diamond Model
Appropriate Scenarios:
- Industry Analysis: Useful for analyzing and understanding the competitive landscape of industries within a particular country.
- National Economic Strategy: Can aid in developing strategies for national economic development and identifying areas of potential competitive advantage.
Strategic Application:
- Business Strategy Development: Helpful for businesses in understanding the competitive forces at play in their industry and how they can position themselves more effectively.
- Policy Making: Useful for policymakers in identifying areas where government action could enhance national competitiveness.
How to Use Porter’s Diamond Model
Implementing the Framework:
- Factor Conditions: Analyze the nation’s position in factors of production like skilled labor, infrastructure, and technology.
- Demand Conditions: Examine the nature of home-market demand for the industry’s product or service.
- Related and Supporting Industries: Identify the presence or absence of supplier industries and related industries that are internationally competitive.
- Firm Strategy, Structure, and Rivalry: Assess the conditions governing how companies are created, organized, and managed, as well as the nature of domestic rivalry.
Best Practices:
- Comprehensive Analysis: Consider all four aspects of the diamond in conjunction to get a holistic view of the competitive advantage.
- Combine with Other Models: Use in conjunction with other economic and industry analysis tools for a more comprehensive analysis.
- Contextual Adaptation: Adapt and modify the analysis based on the specific economic and industry context.
What to Expect from Implementing Porter’s Diamond Model
Insights into Competitive Advantage:
- Understanding of National Strengths and Weaknesses: Provides insights into a country’s competitive strengths and weaknesses in the global marketplace.
- Identification of Key Success Factors: Helps identify key factors that contribute to the success or failure of industries within a particular country.
Strategic and Policy Implications:
- Informing Strategy and Policy: Can inform both business strategies and government policies aimed at enhancing competitive advantage.
- Guidance for Resource Allocation: Offers guidance on where to allocate resources for maximum competitive impact.
Limitations in Application:
- Potential for Misinterpretation: Be cautious of oversimplifying or misinterpreting complex economic realities based on the model.
- Need for Dynamic and Holistic Approach: Recognize the need for a dynamic and holistic approach that considers both domestic and global economic forces.
In summary, Porter’s Diamond Model is a valuable tool for analyzing a nation’s competitive advantage, particularly in understanding the factors contributing to the success of industries within a country. However, it should be used with an awareness of its limitations, including its primary applicability to developed economies and its relatively static nature. The model is most effective when used in conjunction with other economic analysis tools and when adapted to the specific context of the industry and country being analyzed. It provides a framework for understanding the competitive forces at play and can inform strategic decision-making at both the business and policy levels.
Porter’s Diamond model examples
Below is a look at how Porter’s Diamond model can be applied to some well-known companies.
Apple
- Firm Strategy, Structure, and Rivalry – Apple was founded in arguably the most innovative and entrepreneurial country in the world, with early rivals such as IBM, Xerox, Commodore, and Tandy all competing for a slice of the emerging consumer electronics market. Today, Apple’s business strategy consists of hardware expertise, superior design, enhanced customer experience, and the integrated Apple ecosystem.
- Factor conditions – Apple is based in Silicon Valley, California, so the company has access to a vast, skilled workforce. However, most product assembly occurs in China where labor is cheaper.
- Demand conditions – the company enjoys significant demand for its innovative technology products around the world. Provided the company can continue to execute its strategy, this demand is likely to be sustained.
- Related and supporting industries – as noted earlier, Apple benefits from the increased collaboration that occurs between related companies in Silicon Valley. Apple also has a simple but effective supply chain, purchasing components from suppliers and then shipping them to China for assembly. It works with a small number of key suppliers, which means it can facilitate better relationships with each.
BMW
- Firm Strategy, Structure, and Rivalry – BMW has several domestic and international rivals with similar brand equity and prestige. In the local German market, the company is using a strategy that combines market relevance, research and development, and competitive services. It also manufactures vehicles consumers can relate to on an emotional level.
- Factor conditions – BMW benefits from a robust German automotive industry that comprises a specialist workforce, world-class infrastructure, and market-leading research and development. German students benefit from a holistic education system where apprenticeships are undertaken in conjunction with vocational training to produce well-rounded automotive graduates.
- Demand conditions – in FY2021, 2.622 million vehicles were sold in Germany alone, with BMW the third-best seller with 222,481 vehicles. The German market is considered to be the largest and most stable in Europe and is predicted to have a market volume of $90.65 billion by 2026.
- Related and supporting industries – like all vehicle manufacturers, BMW relies on an extensive network of over 100 components suppliers. Over 43% of these are located in Germany or are subsidiaries of companies based in the country.
Louis Vuitton
- Firm Strategy, Structure, and Rivalry – in France where the company was founded, the luxury goods market is extremely competitive and in recent years has been disrupted by new technology. In response, Louis Vuitton has embarked on a well-documented acquisition strategy, combining with champagne producer Moët Hennessy to form luxury brand conglomerate LVMH.
- Factor conditions – French culture is synonymous with fashion and luxury, characteristics that were instilled by King Louis XIV who established a powerful textile industry to support the economic wealth of the nation. This culture continues today with a workforce of craftspeople that are sometimes required to train for up to two years before becoming certified.
- Demand conditions – the culture of luxury has also meant that discerning French consumers continue to demand opulent products. Demand has also soared in new markets such as China which has enabled Louis Vuitton and its subsidiaries to expand and maintain competitive advantage.
- Related and supporting industries – as noted, the luxury goods industry has close ties with the French textile industry. It is also linked to apparel, garments, embellishments, and sewing machinery. These elements comprise an ecosystem where every constituent part is motivated to innovate and succeed for the collective good.
IKEA
- Firm strategy, structure, and rivalry – IKEA has a focus on three core components: sustainability, climate change, and diversity across its entire value chain. Business strategy is based on the IKEA Concept which promotes the idea that furniture should combine function, value, quality, and design. IKEA has few notable rivals in its home market of Sweden, but Walmart, Amazon, Sears, and Wayfair are its main competitors in the American market and elsewhere.
- Factor conditions – in Sweden, IKEA has access to a diverse, skilled, and educated workforce who understands the Scandinavian culture on which the company is based. While most of the sales and design work is done in Sweden, manufacturing is outsourced to China and other Asian countries. Access to natural resources has also been problematic for IKEA, with the company frequently associated with timber sourcing in countries such as Russia, Ukraine, and Romania.
- Demand conditions – demand for affordable flat-pack furniture enabled the company to expand around the world, but a new trend is emerging in 2022 around environmentally-conscious, second-hand purchases. In the wake of the COVID-19 pandemic, consumers are also looking for more outdoor furniture and products that can satisfy hybrid living spaces for work, play, and entertaining.
- Related and supporting industries – IKEA manages a vast supply chain with over 1,600 suppliers across the home furniture, components, food, and transport industries. To ensure its core sustainability values are upheld by suppliers, the company developed the IWAY code of conduct system which stipulates various requirements and standards.
Starbucks
- Firm strategy, structure, and rivalry – Starbucks’s strategy is based on continued investment in customer service to increase brand equity and quality-based differentiation. The company also has a focus on making a positive impact on the planet and its employees. Primary competitors include McDonald’s, Tim Horton’s, and Dunkin’ Donuts, with the company also competing with Nestle and Lavazza for coffee and related product sales. Intense competition has led to innovative products such as a bean-to-cup traceability tool, enhanced customer rewards programs, and a recently released line of RTD cold coffee drinks.
- Factor conditions – Starbucks has access to a young, savvy, social, and relatively skilled workforce in the United States and other Western markets. The company offers barista and management training to its employees so that they embody the company’s customer-centric values and deliver the Starbucks Experience. The vertically integrated coffee bean supply chain is also an important factor condition for Starbucks.
- Demand conditions – demand for coffee and coffee-related products is not likely to decrease any time soon. In the United States alone, over 400 million cups of coffee are consumed daily by around 150 million consumers. In 2022, coffee consumption soared to a two-decade high with over 66% of Americans drinking it each day. Demand has increased because consumers – many of whom were stuck at home during COVID-19 lockdowns – developed an interest in making their own coffee or a taste for specialty coffee products.
- Related and supporting industries – as hinted at above, Starbucks owns or at least enjoys positive working relationships with its coffee bean suppliers. The company has also recently moved into the coffee machine industry, selling a range of branded, self-serve machines to other businesses. Starbucks also sells coffee-pod machines to consumers for use in the home. Without the development of coffee machines and coffee pod technology from other manufacturers, it is unlikely Starbucks would have achieved the same level of penetration in the at-home consumer market.
