3.16 - Boston Matrix Analysis
The structure and purpose of the Boston Matrix
The Boston Matrix is a tool created by the Boston Consulting Group to help businesses evaluate their range of products. It assists in understanding how products perform in terms of market position and potential, guiding decisions on resource allocation.
How the Boston Matrix is structured
The matrix uses a grid with two axes to plot products:
- Vertical axis - Market growth rate (from high at the top to low at the bottom), showing how quickly the overall market for the product is expanding.
- Horizontal axis - Market share (from high on the left to low on the right), indicating the product's share of sales compared to competitors.
Products are represented as circles on the grid, where the size of each circle shows the revenue generated by that product. This visual setup divides products into four categories based on their position.
The purpose of using the Boston Matrix
Businesses apply the Boston Matrix to:
- Assess the current performance of their product range.
- Decide on actions for existing products, such as increasing promotion or phasing them out.
- Plan for launching new products to maintain a balanced portfolio.
The characteristics of cash cows, stars, question marks, and dogs
The Boston Matrix classifies products into four types based on their market growth and market share. Each type has distinct features that influence how a business manages them.
| Category | Market growth | Market share | Key characteristics |
|---|---|---|---|
| Cash cow | Low | High | Established products in stable markets that generate strong profits and cash flow with minimal promotion, due to high customer recognition. The cash can fund other products. |
| Star | High | High | Strong performers in growing markets that earn high revenue but need significant investment in promotion to stay competitive amid rapid changes. |
| Question mark | High | Low | Products in expanding markets that require heavy resources for promotion but yield low returns currently. They have uncertain futures and may need updates or withdrawal if performance does not improve. |
| Dog | Low | Low | Underperformers with limited sales, poor cash flow, and weak future prospects. They often require replacement or complete market exit. |
Marketing strategies based on the Boston Matrix
The Boston Matrix informs specific strategies to manage products effectively. These approaches aim to optimise the product portfolio by leveraging strengths and addressing weaknesses, ensuring overall business sustainability.
Key strategies linked to product categories
- Building - Invest in question marks through increased advertising or better distribution to boost market share, often funded by cash from cash cows.
- Holding - Continue supporting stars with resources to protect their leading position in dynamic markets.
- Milking - Extract maximum cash from cash cows with low ongoing costs, using the funds to develop other products in the range.
- Divesting - Cease production or sales of dogs to free up resources, avoiding further losses.
A balanced portfolio is essential; an overload of dogs or question marks can lead to cash flow problems, while a mix including cash cows and stars supports long-term stability.
Limitations of the Boston Matrix
While useful, the Boston Matrix has drawbacks that businesses must consider when applying it. It provides a snapshot but does not capture all aspects of product performance.
Main limitations of the tool
- Lack of future prediction - It only shows the current status of products and cannot forecast success or failure without additional market research.
- Oversimplification - The matrix reduces complex influences on product success, such as consumer trends or external events, to just two factors.
- Assumptions about profits - It presumes that high market share always leads to high profits, which may not hold true in all cases.
- Ignores external factors - Competitor actions, technological advancements, and economic shifts are not accounted for, potentially leading to incomplete analysis.
