ned by any other unit. This also brings means that ERP allows real time data processing (Vathanopas, 2007, Gupta, 2000, Nah et al., 2001). However, these functionalities require involvement and support of all level of employees from top management downward to shop-level employees (Amoako-Gyampah, 2004).

(Benefit SAP-6) R/3 helps in separating duties in an organization (Little and Best, 2003). Other than R/3 usefulness, one of ERP’s major strengths includes the restructuring companies to a better position (Nah et al., 2001, Willis and Willis-Brown; 2002; Kim et al.; 2005; Hong Seng Woo, 2007). While ERP may empower management and serve employees, customers and suppliers needs (Willis and Willis-Brown, 2002), this may lead to greater companies value (Spathis and Constantinides, 2003). The study of Spathis and Constantinides (2003) prove ERP offer huge significant benefits on accounting information and management processes. In addition to that, the sample company in Amoako-Gyampah (2004) study of which a healthcare products organization with over 20,000 employees worldwide chose SAP R/3 as they claim SAP‘s tight integration philosophy met their business need for integration. Furthermore, ERP offer seamless data integration or cross-functional within the companies (Amoako-Gyampah, 2004). This corroborates the purpose of ERP where it is designed to provide one common source of data. Lastly, ERP adopters may enjoy the productions of real-time data which is shared across the organization (Amoako-Gyampah, 2004, Mustacello and Chen, 2008; Finney and Corbett, 2007).

(Cost SAP -6) Perhaps, one of its shortcomings is the pain during implementation (Gargeya and Brady, 2005). For the adopters, the organization’s long term implementation process may cause fatigue and dissatisfaction. Worse, this also may cause imperfect system design and testing (Trimi et al., 2005). Moreover, the greatest disadvantage of an ERP system (Trimi et al, 2005) is stiff and expensive to implement (Bradley and Lee, 2007, Gargeya and Brady, 2005, Spathis and Constantinides, 2003). Implementation costs include software, hardware, consultant fees, cost for staff to operate the system and the very large cost component of user training (Trimi et al. 2005). This leads to over budget, in average of 189 percent for many companies, especially failed projects (Gargeya and Brady, 2005). The complexity of the system is another major complaint (Willis and Willis-Brown, 2002, Bradley and Lee, 2007). Consequently, companies will face high resistant to change from employees (Spathis and Constantinides, 2003) as employees do not insist to learn new ERP system due to its non-user friendly features compared to old system (Bradley and Lee, 2007, Pijpers and Montfort, 2006).

(CSF) With all the costs and disadvantages of ERP, increasingly we hear of the fall short of ERP implementations (Willis and Willis-Brown, 2002, Nah et al., 2001, Finney and Corbett, 2007; Gargeya and Brady, 2005). Resultantly, there has been long-drawn-out investigate concerning on critical success factors (CSF) of ERP implementations (Finney and Corbett, 2007; Gargeya and Brady, 2005, Kim et al., 2005, Hong Seng Woo, 2007; Mustacello and Chen, 2008). Accordingly, as suggest in prior literature, in order to ensure success of SAP implementation, C本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
