“…For example, scholars indicate that services have higher margins than products (Anderson, Fornell, & Rust, 1997), and a more stable source of revenue and more resistant against fluctuations compare with products (Quinn, 1992). Therefore, manufacturing firms develop offerings (and form value propositions that are reciprocal promises of value between firm and customer (Ballantyne & Varey, 2006)) through for example pro-active maintenance, upgrades, performance-based contracts and consultant-services (Brax, 2005;Gebauer et al, 2012;Penttinen & Palmer, 2007;Windahl & Lakemond, 2010) and also involve the customer in the innovation process to identify current and future customer needs to develop offerings (Ettlie & Rosenthal, 2011;Noordhoff, Kyriakopoulos, Moorman, Pauwels, & Dellaert, 2011). Researchers suggest that innovation in general is becoming a major factor for a firm's competitiveness (Fitzsimmons & Fitzsimmons, 1999), with service innovation being particularly advantageous (Bettencourt, Brown, & Sirianni, 2012).…”
