In this paper we investigated the use of open and collaborative innovation to produce cost-effective Enterprise Systems. Therefore we carried out a literature review on existing innovation models and used cognitive and sociotechnical engineering to propose a conceptual innovation model that addresses a healthcare issue in the National Health Service (NHS) in the UK. The following sections provide information about our methodology, results of our literature review in ES, cognitive and social-tech engineering and innovation management. Later, an analysis and prioritization of innovation models is carried out and a conceptual innovation model is presented. Finally, conclusions are outlined.
