Abstract:

User centred design is an approach that helps all members of a development team balance the needs of customers with the commercial objectives of the product. Properly executed, it guarantees commercial success for a product because customers are involved at every phase of the development. It also ensures business objectives are met and stops products from being over-engineered.
