I know this is not scientifically proved; it is just a thought that crossed my mind in class today
The moment a product-based company states "We are a solutions/services company" will signal you the moment that company thinks has lost (or will lost) its niche.
I can't recall any example of a product-based company that has successfully transformed itself in a solutions/services company. Can you?

Jaime Cuesta and some other friends reminded me that IBM is a good example of a company that has transformed itself from a product-based company into a services/solutions company. I agree, it is a good example.
