“…Studies on ERP implementation projects varied in their orientation. The normative stream of research is partly dedicated to identify the "critical success factors" required to achieve a successful ERP implementation and reap its benefits (Al-Mashari, Al-Mudimigh and Zairi, 2003;Al-Mudimigh, Zairi and Al-Mashari, 2001;Brown and Vessey, 1999;Colmenares and Leopolodo, 2004;Holland, Light and Gibson, 1999;Hong and Kim, 2002;Parr, Shanks and Darke, 1999;Ross and Vitale, 2000;Scott and Vessey, 2000;Skok and Legge, 2001;Umble, Haft and Umble, 2003). Other studies within the normative stream, focus on identifying the consecutive stages or "life cycle" that an ERP implementation project should follow within the buyer organization (Brehm and Markus, 2000;Lee and Lee, 2000;Markus and Tanis, 2000;Parr and Shanks, 2000;Ross, 1999).…”
