“…In these cases data collection methods are usually questionnaires (Rauch and Wilson, 1995;Vredenburg et al, 2002b;Venturi and Troost, 2004;Ji and Yun, 2006), interviews (Bekker, 1995;Borgholm and Madsen, 1999;Boivie et al, 2003;Boivie et al, 2006;Bruno and Dick, 2007), or a combination of both (Rosenbaum et al, 2000;Gulliksen et al, 2006;Neumann et al, 2009). Informants are mostly usability specialists and interaction designers, and the focus is usually not so much on the product development process and team as a whole, but on usability-related activities and usability departments.…”
