Question 1

Can a 'Dog' product ever be kept by a business?

Accepted Answer

Yes. The matrix is a simplification. A 'Dog' might be kept for strategic reasons, such as completing a product range to satisfy key distributors, or if it was a founding product with sentimental value. It might also be used as a 'loss leader' to attract customers to more profitable products (synergy). The cost of divestment could also be higher than the small loss it makes.

Question 2

Is high market share always good and low market share always bad?

Accepted Answer

Not necessarily. High market share (like a Star or Cash Cow) is generally desirable as it can lead to economies of scale and market power. However, it might have been achieved through costly price wars, reducing profitability. Conversely, a low market share product (a Dog or Question Mark) could be operating profitably in a small, niche market. The matrix doesn't show profitability, which is a major limitation.

Question 3

How does a business define 'high' and 'low' for market share and growth?

Accepted Answer

This is a key weakness of the model as there is no universal standard. 'High' relative market share is often defined as being greater than 1.0 (i.e., having a larger share than the next biggest competitor). 'High' market growth is often benchmarked against the economy's GDP growth rate, with anything significantly above (e.g., >10% per annum) considered high. However, these are just guidelines, and the divisions are arbitrary, which can lead to different classifications for the same product.
