In IS research we live with positivistic roots which have recently been criticized as focused on “singular, independently existing reality that is more or less given, and undergoing linear changes within a four-dimensional space”. This is what we according to prevailing norms need to do in order to get valid research results in empirically oriented IS research. In contrast with that, IS research in the 21st century will have to deal with “inherently uncertain, distributed, complex and multiple reality, hyperconnectivity, increasing speed of all processes, nonlinear and global changes”? We will use the arena for mobile value services as the context for working out what is required of performative IS research and to find out if science precision and practice relevance can both be met in the new paradigm.
