I’m not a fan of models ! Models are generally used to better conceptualize managers’ thinking but the fact is most people use models to oversimplify complex phenomenons.
However, there is one that I find most inspiring: the Brand Key Model set up by Unilever. To know more about it , have a look at an excellent website recently done by a group of my MBA students (Solvay Brussels School, Saigon):http://image-branding.wix.com/marketing
