Lean but not mean UX: Towards a spiral UX design model

Abstract

A new user experience design model was proposed and evaluated through a case study of a new product development project within a multinational software organization. Strengths and weaknesses in existing and proposed user experience design models were discussed based on how the following three challenges to user experience design - co-evolution of design problem and solution, organizational silos, conceptual integrity in design - affected user experience design quality and productivity through their impact on nature of design tasks and the social context of design activities.
