No Question Marks...
Luc Baz.
The idea of the BCG Matrix is clearly to have a PORTFOLIO of products. In this portfolio there should be cash cows (generating lots of cash) and also some stars and question marks (consuming cash to further develop). This means that the answer to the question is that the firm should invest in R&D and Product Development, especially if there are also no or few Stars. Otherwise the firm will have no growth potential in the future.
