5. Discussion and implications
5.1 Implications for academic research
Despite typical limitations of qualitative research, the findings make four contributions to the academic research. First, the findings reveal that companies can achieve three distinct strategic objectives: rapid sales growth in the market development, market share expansion and new market creation in the maturity phase of the product lifecycle. The first strategic objective extends previous arguments that only under uncertain maintenance and high product cost conditions will companies offer PPU services. Six cases actually deploy PPU services for rapid sales growth during the market development, even if product and service costs are relatively low and very certain. In addition, companies in the market development phase are argued to mostly rely on services improving product sales and ensuring product functionality, with PPU services being one option in the service offering. The results suggest that PPU services could actually dominate the service offerings and replace other services completely (Cusumano et al., 2015).
Interestingly, expanding market share is in line with claims that PPU services attract new customer segments (Cusumano et al., 2015; Sundin and Bras, 2005). The strategic objective on new market creation links PPU services to the argument that strategic innovations reshape the existing business model, opening-up uncontested markets, and creating a leap in customer value (Christensen et al., 2002; Matthyssens and Vandenbempt, 2008). Overall, these insights offer systematic evidence on strategic objectives of PPU services. Future research can investigate companies that focus on one objective rather than multiple ones. It would be also useful to investigate how these strategic objectives contribute to the overarching goal of PPU services increasing sustainability (e.g. more sensible consumption, more resource-efficient product design) (Bocken et al., 2014; Manzini and Vezzoli, 2003; Williams, 2007).
