“…Studies investigate, e.g., the suitability of specific customer and user groups for integration in certain stages of the service innovation process (Alam, 2006(Alam, , 2002Carbonell et al, 2012;Kristensson et al, 2008;Magnusson et al, 2003;Matthing et al, 2006Matthing et al, , 2004Skiba and Herstatt, 2012), suitable methods and benefits of customer integration in new service development (Martin and Horne, 1993;Melton and Hartline, 2010). Further studies examine inter-organisational innovation (Gottfridsson, 2012) or focus on innovation activities with suppliers as another external source for ideas and expertise (Ngugi et al, 2010). Whilst these research initiatives create valuable insights for specific actors in the service system, research considering the co-existence and the interdependence of external stakeholder integration with the internal innovation management of the organisation (Perks and Riihela, 2004) is still scarce: Perks et al (2012) as well as Schleimer and Shulman (2011) contribute with work including the co-existence of collaboration with internal and external stakeholders.…”
