Achieving business flexibility is a necessary condition for the business development of SMEs, especially nowadays due to the global market downstream. The business flexibility implies flexibility in the underlying ICT infrastructure and business processes. Moreover, in the current climate, midsize organizations also need to achieve flexibility in an affordable way, since in the current economic climate, organizations are under pressure to freeze expenditure and wring ever more return from existing assets.Business process management (BPM) is a class of software which directly contribute to enterprise performance by driving operational excellence and business flexibility. However, current solutions for BPM are tailored to the need of big companies, are quite expensive and drive mainly technology flexibility and not necessarily business flexibility.ReFLEX aims at strengthening the competitiveness of the SME participants by developing a new BPM model tailored to the need of SMEs for being continuously aware of the changes in the environment and to change/adapt themselves accordingly in order to keep the business process running well. Indeed, in that way SMEs will increase their responsiveness on the new business opportunities (or threats) which is a crucial feature for the business development (even survival) for small fishes in big oceans of the globalized economy.However, in order to realize the dynamic BPM, a substantial research on the new model for the description of (ad-hoc) dynamic business processes is needed. This includes the development of a novel workflow engine that will be able to execute such processes as well as the calculation of changes on the fly. ReFLEX aims to perform this research in order to develop, deploy, validate and exploit such an approach for the benefits of SMEs. Additionally, ReFLEX will develop and validate the business models for participating SMEs, especially non-IT service providers in order to ensure the business value return.
