July's Harvard Business Review article "Engineering Reverse Innovations" explains why you shouldn't develop innovations for Developed countries and then just expect them to be successful in D&E markets with some minor adaptations. The article (which is really good, by the way) explains five design principles to showcase how to develop a product for D&E, but I would sum it up in another very basic principle - "Develop your innovation in its usage environment". Make sure that your product is suited to the way it is meant to be used by conceptual design - if you do it that way, you maximise your chances of success. And, by the way, this is not only valid for D&E - it is valid for every single market and product.
