The Boston Consulting Group (BCG) matrix, also known as the product portfolio matrix, is a tool used to assess the strategic position of a company’s brand portfolio.
The BCG matrix was developed in 1968 by Boston Consulting Group founder Bruce Henderson in a short essay titled Perspectives. At its peak, Henderson’s model was used by approximately 50% of all Fortune 500 companies. Today, it is still one of the most popular product portfolio analysis methods and is a central component of many business school curriculums.
The approach places a firm’s products and/or services into a 2×2 matrix with four quadrants that measure market share and growth rate. Each quadrant is described as follows:
- Question marks – high market growth/low market share products.
- Stars – high market growth/high market share products.
- Dogs – low market growth/low market share products, and
- Cash cows – low market growth/high market share products.
In this article, we’ll explain some BCG matrix examples from the likes of Coca-Cola and Apple.
Contents
Coca-Cola
Coca-Cola is one of the most recognizable brands in the world, but its true global presence combined with shifting consumer preferences means it does not necessarily dominate every market it enters.
- Question marks – as the soft drink industry undergoes rapid transformation toward healthier alternatives, the question mark quadrant is perhaps the most important to Coca-Cola. To that end, the company has invested a lot of money in low or no-calorie drinks such as tea and fruit juice. Diet-Coke is another product that falls within this quadrant. Despite attempts by Coca-Cola to market it as a healthier alternative, the product has not been able to gain significant traction.
- Stars – bottled water is one product that Coca-Cola has been able to move from the question mark quadrant to the stars quadrant. Brands such as Kinley, Dasani, and Glaceau Smartwater are significant players in the rapidly growing bottled water market. In the United States alone, sales of the latter two brands accounted for $1.911 billion in sales during 2021.
- Dogs – Coca-Cola Life is an example of one product that falls in the dogs quadrant. The product, which was a lower-calorie version of Coca-Cola, was made with the natural sweetener stevia. Critics derided the company for greenwashing, but, in any case, consumers showed little interest in the natural alternative.
- Cash cows – the Coca-Cola company has quite a few cash cow products, none more significant than Coca-Cola itself. Growth is limited since the product is sold in more than 200 countries and territories around the world. However, the drink remains immensely popular and a market leader despite a decline in global soft drink sales.
Apple
Apple can boast a diverse product line that caters to a wide audience base. Let’s take a look at various Apple products in terms of the BCG matrix.
- Question marks – while Apple has a dominant market share in many contexts, Apple TV and Apple AirPods face strong competition from both established brands and smaller companies. Apple TV in particular is a reasonable quality product that was simply ahead of its time. It may become more popular when consumers can appreciate the importance of the fact that it is part of the Apple ecosystem.
- Stars – the Apple iPhone is a star product that continues to deliver. With each update, the iPhone seems to set new innovative standards and smash previous sales records. The iPad and Smartwatch are not far behind.
- Dogs – the iPod could be considered an example of a dog product. While it only took the company five years to sell 100 million iPods, the longevity of the portable music player market was cut short by smartphone innovations and the rise of music streaming services.
- Cash cows – in terms of cash cows, the MacBook, iMac, and iPad enjoy relative dominance in their respective markets. These three products enjoy high brand equity, with devoted consumers more likely to purchase Apple products over comparable (and sometimes cheaper) alternatives.
Key takeaways:
- The Boston Consulting Group (BCG) matrix, also known as the product portfolio matrix, is a tool used to assess the strategic position of a company’s brand portfolio. The matrix was developed in 1968 by Boston Consulting Group founder Bruce Henderson.
- Coca-Cola is one of the most recognizable brands in the world but is not immune from failed product launches or intense competition. As the soft drink industry wanes and consumers choose healthier alternatives, the question mark quadrant is perhaps the most relevant to the company’s long-term success.
- For Apple, products in the question mark quadrant may become more successful over time since they are integrated with other, more popular products. The iPhone, iPad, and Smartwatch are all products that enjoy tremendous market share, while the company’s laptop and desktop products are considered cash cows.
