What is the BCG Growth Share matrix?
The BCG matrix (aka Boston Matrix) is a strategic planning tool which uses the relative market share and growth rate to assess the relative strength of products in a brand’s portfolio.
This is based on Market Share and Growth. The BCG model assigns products into four categories – Stars, Cash Cows, Question Marks, and Dogs – quickly identifying which products need attention and helps to inform their investment strategy.
This growth vs share model provides an indication of which products an organization should invest in, those they should develop, and the ones they should get rid of.
The model advocates that a company milks their cows, doesn’t waste money on the dogs, invests in the stars and applies some resources to the question marks to identify if they can become stars.
BCG VS Growth Share Matrix – is there a difference?
Essentially there is no difference. The growth share matrix was the brain child of Boston Consulting Group’s founder Bruce Henderson in 1968 and published in a provocative essay called Perspectives. It was used by about half of the all Fortune 500 companies.
Over time it was also given the names of BCG growth-share matrix, Boston matrix, product portfolio matrix, Boston box, Boston Consulting Group analysis, or a portfolio diagram.
Why use the BCG matrix?
The BCG matrix is a simple, easy to use tool that:
- Identifies products that are profitable now, those with potential, and those which are, or could be, a drain on resources
- Informs resource allocation across a product portfolio
- Helps a company establish strategies to be a market leader through a sustainable portfolio of products and services that capture and services particular range of consumer markets.
- Provides a visual representation of a company’s product portfolio across the aspects of potential growth and relative market share.
Who should use the BCG matrix?
The BGG matrix is mainly used by internal management that has more than one product competing for resources. It can inform a number of different business functions including marketing, strategy, and portfolio planning.
Generally, this is only suited to companies who provide multiple products and/or services and looking to refine or consolidate their internal business strategies. Single line companies may be better served by the use of a competitor analysis perceptual map.
Limitations of the BCG Matrix
The BGG Matrix provides a resource allocating framework between different business units but there are certain limitations. These include:
- The market needs to be clearly defined for this to be effective.
- Having a high market share does not necessarily equate to profits. The overall goal of the business needs to be considered. High market share also may require a high level of investment.
- At times, dogs may be playing a support role such as a lost leader and help other parts of the business gain or maintain a competitive advantage, sometimes earning more than cash cows. The model suggests simply removing this part of the quadrant but should be considered at a high level across its overall fit in the business.
BCG matrix example
The BCG matrix template plots products or product categories against two variables:
- Relative Market Share (horizontal axis) – the higher the market share, the more cash likely being generated. This measurement reflects a brand’s competitive position and is usually expressed as their market share relative to their closest competitor.
- Relative Market Growth (vertical axis) – products with high market growth rate usually have higher earnings but also consume lots of cash and require investment to pursue and maintain that growth. Market growth is a good indicator of industry attractiveness and gives an indication of a product’s future potential, overall market strength, and attractiveness to future competitors.
- have the potential to gain market share and become stars
- may eventually become cash cows when market growth slows
- can become dogs if they don’t succeed in becoming a market leader after a period of investment or the market growth declines.
Dogs (or pets)
- usually generate minimal profit
- are sometimes maintained for strategic purposes e.g., they provide jobs, have synergies with other business units, or are a defense against competitors.
Suggested action: Consider eliminating these products by retrenching, divesting, or liquidating. Maintain (in special circumstances) where it is supporting other products to maintain a competitive advantage or is cash positive.
- are question marks that have gained market share and are improving.
- can become cash cows as the market stabilizes.
- may become dogs if they lose their competitive edge, and the market becomes obsolete (not uncommon in technology fields).
- generate good profits and supply funds for future growth
- were often stars in the market which has now matured and slowed
- don’t have many opportunities to expand as the market is growing too slowly for investment to be worthwhile.
- might become stars with further product development.
Suggested action: Support to maintain their current market share. “Milk” while investing as little as possible. Consider investing in product development, diversifying, divesting or retrenching. This requires optimal allocation to maintain its status.
How to use a BCG analysis
The BCG matrix is based on the theory that in a natural business cycle, products usually start as question marks, then become stars as the market grows. When that growth slows they become cash cows and eventually dogs. A diversified company will have products across the spectrum to ensure future growth and funding.
Using the BCG matrix, you can either pre-populate items or ask people to add in items under each quadrant. They can add attachments, files, descriptions or other information to justify their current position. Leading a discussion allows everyone to look at the overall placement and see if there is a need to adjust their positioning.
Now comes the important aspect of having people brainstorm strategies and actions against each of those strategies. They can be added as comments, and then once confirmed, turned into action items.
Identify products in the portfolio you’d like to consider.
Position the products on the matrix.
Identify actions based on the strategic options for the BCG categorization.
Share the outcomes of the session, including the action plan, with stakeholders.
