The software industry is currently experiencing a paradigm shift from traditional installable applications to web-based software, where applications consisting of data, code and other resources live on the Web as services and can be located anywhere in the world. In the future, cloud technology will represent a major part of daily life. Active use of Internet applications will become common practice when, for example, consumers store, use, and distribute material they have created themselves. The Cloud Software Program forms a partner network of 20 Finnish enterprises and 8 research organizations in Finland. The project aims to generate breakthroughs in the field of cloud technologies, Lean enterprises and business models, integrating user experience and security as value-adding elements. Our group is conducting several studies in areas such as operational excellence, lean and transparent enterprise, and is involved in the development of a cloud-based application platform.
