The approach analyses the needs of consumers to be filled by products and services, and uses results as a basis for innovation. It is a natural next step after efforts to clean up production processes and re-designing products, which invites business to shift focus from selling products to selling utility. A mix of products and services can thereby meet client demands with less environmental and social impacts. A brochure outlines the concept.
