6.1.4—Boston Consulting Group matrix

BCG maps products by relative market share and market growth into stars, cash cows, question marks and dogs.

The categories suggest cash allocation but ignore synergies, margins and future uncertainty.

State the axes and decide whether investment, harvest or exit is justified.

A high-share, low-growth product may fund a high-growth question mark.

A dog is not automatically worthless if it supports another product.
