TopIntroduction
Modern organizations face the severe challenge of expanding market, reducing operation cost and rising customer expectations. To respond to competitive environment in a business world, many organizations have invested in new information system (IS) in the hope to reduce operation cost and increase productivity (Avgerou, 2001; Chung & Snyder, 2000). Specifically, for the last two decades, enterprise resourcing planning (ERP) system has been introduced by many organizations in order to improve workflow and increase the efficiency of shared services and single database operations with streamlined processing, reporting, and access across operating units (Jacobson, Shepherd, D’Aquila, & Carter, 2007; kogetsidis, Hokkinaki, & Soteriou, 2008; Lee, Lee, Olson, & Chung, 2010; Momoh, Roy & Shehab, 2010; Rao, 2000).
In essence, ERP system is a software solution integrating the various functional spheres in an organization – a link through the entire supply chain, aimed at best industry and management practices for providing the right product/service at the right time, at the right place, at least cost (Rao, 2000). From a business standpoint, the benefits that a properly implemented ERP system can offer an organization include time and cost reduction in business process, faster transaction processing, improvement of operational performance, financial management and customer service, web-based interfaces and more effective communication (Kogetsidis et al., 2008).
Despite the benefits of implementing ERP system, numerous studies have reported unusually high failure rate in implementing it due to variety of challenges (Ho, Wu, & Tai, 2004; Razmi et al., 2009; Momoh et al., 2010). This brutal fact reveals that understanding how to implement ERP system successfully is a high priority for both researchers and practitioners (Cho, Park, & Michel, 2011; Momoh et al., 2010; Razmi, Sangari, & Ghodsi, 2009; Venkatesh, 2000). In this regard, Davis’ (1986) technology acceptance model (TAM) and its extended model (TAM2; Davis, Bagozzi, & Warshaw, 1989) are widely applied in exploring the inner working mechanism of users’ acceptance and usage of new IS (Bhattacherjee & premkumar, 2004).
Indeed, there is a large body of research on successful adoption of ERP system supporting the impact of such perceived ease of use on initial user acceptance and sustained usage of new IS (Bhattacherjee & premkumar, 2004); Nevertheless, TAM’s universality to predict across all situations has recently been called into question (Greenfield & Rohde, 2011). Specifically, it is pointed out that fewer efforts have been devoted to understanding the determinants of attitude toward ERP from the perspective of the social fabric/effects (Venkatesh, 2000; Avgerou, 2001; Kotlarsky & Oshri, 2005). For example, as Koh, Simpson, Padmore, Dimitriadis, and Misopoulos, (2006) and Kotlarsky and Oshri (2005) argued, neglecting human and social factors constituted a major problem while implementing ERP system. Further, in many cases, the reason for new IS implementation failure is a lack of change management (McAdam and Galloway, 2005; Momoh et al., 2010; Ziemba & Obłak, 2015).
