What is the BCG Matrix? The theory

The BCG Matrix is an assessment model in which products or (functional) business units are assessed on two aspects. First, the relative market share that a certain product or its business unit has with respect to the competition. Second, the market growth potential for that product or its business unit.

For manufacturing businesses it is very functional to have a prior understanding of the market position of their products. Besides knowing which products need to be promoted more, they will know which products will be successful.

For this purpose, the American Boston Consulting Group (BCG) developed the BCG Matrix in which products or (functional) business units are assessed on two features:

  1. The relative market share that a certain product or its business unit has with respect to the competition.
  2. The market growth potential for that product or its business unit.

The definition of the BCG Matrix

The BCG Matrix is a portfolio management framework that helps companies decide how to prioritize their different businesses. It is used by organizations with high growth rates and a high market share in many high growth markets. This assessment model is also known as the Boston Matrix, the Growth Share Matrix or Boston Consulting Group Matrix.

BCG Matrix categories and an example

The absolute values of the axes are dependent on the line of business or industry. This is why the axes are often indicated with high and low. Based on the BCG Matrix a product or business unit can be in one of the four following categories:

Figure 1 – BCG Matrix: the four quadrants

1. Question mark

It is still a big question (problem child / wild cat) what the product is going to do on the market. Often it is concerns a product that is to be introduced and is unknown with a very small market share. It is still uncertain whether it can become a Star or a Cash Cow.

2. Star

The market share of the product grows like a ‘rising star’ in the growth market. With targeted investments such as innovations and adjustments to the product, this lead in the market is maintained. The product will become more and more familiar.

3. Cash Cow

The product is a ‘milch cow’ and big money is made from this. The revenue from the Cash Cow is invested in other products.

4. Dog

When a product is in the underdog position, it has a small market share in a mature market. If this product is no longer of strategic importance to the company, this product will be divested.


The most ideal development path of a product is that from Question mark to Star and Cash Cow. The route to Dog should be postponed for as long as possible. Some products remain stuck as a Question mark and become Dogs at an early stage. This is a costly affair for a business as investments have been made in the product and in the promotion around the product.

The route of a product via the ideal development path will eventually bring in money with which investments can be made in other and/or new products that will be deployed in the market as a Question mark. However, for the sake of the continuity of the Cash Cows and / or Stars, Dogs are also necessary.

Example: Fast food restaurants in America almost always offer soft drinks (Dog) for free in combination with a hamburger (Cash Cow). As a consequence, the sale of the Cash Cows is guaranteed.

The BCG Matrix and Strategic choices

Operational management can be determined from the BCG matrix. For a company it entails a lot of risk to fully aim at one of the four categories and from a strategic point of view it is better to distribute the assortment over all four categories.

Some strategic choices that are in conformity with the BCG matrix could be:

1. Build strategy

Create a new brand and a new target audience by means of a Question Mark.

2. Hold strategy

Maintain this success and benefit from market growth by means of a Star.

3. Harvest strategy

Make as much money as possible with the product by means of the Cash Cow. This can be achieved by improving or renewing the product or by manufacturing by-products.

4. Divest strategy

Abandon the investment in the product by means of a Dog; the market is saturated or there is no or little interest in the product.

Criticism on the BCG matrix

Notwithstanding the fact that the BCG matrix is applied by many businesses, it has also been criticized:

  • The market share of the matrix does not guarantee profitability.
  • The BCG matrix does not consider decreasing markets enough; Cash Cows could disappear without reason.
  • Market growth is treated as a given, whereas a business could give the market an incentive.
  • Both axes have been assigned the same value. In practice, this value can depend on the strategy.
  • The coherence as regards content between products and product groups is not incorporated.
  • The BCG matrix does not show what the competition is doing.
  • The BCG matrix may oversimplify the assessments of the facts
