strategic choices

Ansoff is particularly useful if you are asked to suggest strategies as it summarises all the ways in which profits could possibly be increased: market growth, cost savings etc, market development, product development, diversification. For BCG you need several products or divisions and need to have market growth and market share data. I tells you what you should consider doing with each product/division. For example, you should wither withdraw from question marks or invest to make them stars.
