Minimisation of time-to-market strategies can provide companies with a competitive advantage in dynamic and competitive environments. Using parallel innovation processes has been emphasised as one strategy to speed up innovation processes and consequently minimise the time-to-market of innovations. Much innovation today takes place in open structures in which networks play an important role. However, little is known about how innovation networks can facilitate parallel innovation processes. This paper discusses how innovation network structures develop and support exploration and exploitation in parallel innovation processes and in this way sustain speedy innovation processes. A case study of an innovation network is carried out by analysing communication structures and the information contents of emails related to a particular innovation process. The analysis shows how certain characteristics of the network facilitate the parallel innovation process but also how such processes place new requirements on such networks and their management.
