“…Such manuals help users become more productive, reducing the cost of customer support and the cost of field maintenance and increasing the sales and repeat purchase of the brand (Hackos, 1994; Smart et al , 2001). Despite these significant paybacks, a limited number of studies has addressed user manuals in the relevant literature, and those studies have mostly focused on whether consumers consult the manuals (Wright et al , 1982; Peterson, 1984; Mehlenbacher et al , 2002; Tsai et al , 2012), manual usage behavior of consumers (Wright et al , 1982; Jansen and Balijon, 2002) and the ideal design of the manuals (Schriver, 1993; Reinert et al , 2007; Pedraz-Delhaes et al , 2010). Some studies have examined technical documents and documentation issues for specific products, such as software or automobiles (Mitchell, 1993; Wiese et al , 2004; Novick et al , 2008; Van Loggem, 2014) or industrial products (You et al , 2001; Pham et al , 2002; Setchi et al , 2006).…”
