In this paper, we outline management science in a manner that, we hope, will aid future research on individual and city temporalities. Our research question is twofold, but intertwined: how societal temporalities could be innovative understood as conceptive (" aspect of mind that can be used to conceive our world anew 1 ") and generative (" having the power of producing or originating 2 " ,)? How firms could contribute to times design in an innovative way? From our perspective, these questions could be even more generic if we accept the general assumption that firms could be societal mutations producers or contributors. In that, we put aside ethical questions we don't underestimate to concentrate on interactions between societal change, here new time organization, and firm management in public transport sector. First, we propose a social and technical times science overview to better understand contemporary times factory that we observed through two case studies led in intervention-research. That will give a useful framework to underline firm contributions to times design since 19 th. Secondly, that baseline will be used to integrate more specific literature on management science, particularly in organization and design topics. Before going on our vision of conceptive temporalities, we need to clarify some definitions we will use in that paper: times, temporalities, rhythm and temporal regime. We'll speak about times, and not " time " in Augustinian sense (" What, then, is time? If no one asks me, I know; if I want to meet this demand, I do not know ") to mean that time could be polychronical and be described by its manifestations. Using temporalities, we refer to " character of what is in time and time consciousness
