“…With packaged software, the functionalist literature suggests that in order to achieve the "best fit" between product functionality and organisational needs, an understanding of user requirements is critical (Bansler and Havn, 1994;Chau, 1995;Nelson et al, 1996;Sharland, 1991;Stefanou, 2001) and that this will lead to successful implementation and usage (Janson and Subramanian, 1995). User involvement in package selection is seen as essential for determining functionality requirements (Akkermans and van Helden, 2002;Al-Mudimigh et al, 2001;Gremillion, 1982) and it is argued that assessing these needs is necessary for scoping the project in order to reduce costly changes (Markus and Tanis, 2000).…”
