The reality is that it is only the `cash cows’ that are really important—all the other elements are supporting actors. It is a foolish vendor who diverts funds from a `cash cow’ when these are needed to extend the life of that `product’. Although it is necessary to recognize a `dog’ when it appears (at least before it bites you) it would be foolish in the extreme to create one in order to balance up the picture. The vendor, who has most of his (or her) products in the `cash cow’ quadrant, should consider himself (or herself) fortunate indeed, and an excellent marketer, although he or she might also consider creating a few stars as an insurance policy against unexpected future developments and, perhaps, to add some extra growth. There is also a common misconception that ‘dogs’ are a waste of resources. In many markets ‘dogs’ can be considered loss-leaders that while not themselves profitable will lead to increased sales in other profitable areas.
