The challenges of using ICT are widely discussed in the literature. The way of discussing them differs from one study to another. Corbitt's study examined these challenges from two different perspectives: internal and external (Kong, 2003; p. 56). Alwabel and Zairi (2005; p.7) classified them into five categories: dominant, organizational, environmental, communication and technological. Arranda et al. (2005) studied challenges based on business sector, while Jones et al. (2003) believe that there are “perceptual and reality” barriers to the use of ICT. They also add that e-commerce barriers can be classified in two ways: by type of business and by time of incidence (Jones et al., 2003; p.1). Barriers to e-services behave in particular ways depending on the nature of the business, and this is why the importance of contextualizing barriers by sector, activity, organizational and personal profiles has been highlighted (Arranda et al., 2005; Keoy et al., 2006). ;p.115; Kim et al., 2007; Kundi and Shah, 2007; Al-Otaibi and Al-Zahrani (2004) pointed out the nature and environment of business as two factors to consider in achieving successful use of electronic services (Al-Otaibi and Al-Zahrani, 2004; p. 31 ). Lack of organizational capacity and resources constitutes another major organizational challenge for e-government initiatives (Al-Shehry et al., 2006; Al-Alawi et al., 2005; p.612; Chappell and Feindt, 1999; Jones et al., 2003; p.9 Keoy et al., 2006; due to lack of adequately trained workforce (Al-Shehry et al., 2006) A major concern associated with...... middle of document ...... hinders the adoption of e-commerce to. Oman One of these factors is “limited technological knowledge”, which is also due to rapid developments in information technology (Khalfan and Akbar, 2006; p. 296). of technology is one of the most regularly cited factors in the failure of IT projects (Kalakota and Robinson, 2001; p. 454; Kim et al., 2007; p. 353; Cheng et al. ., 2001; p.68). This was found to be true regardless of the size of the organization or the type of activities the organization engaged in (Aranda et al., 2005). A study conducted in Nepal showed that lack of commitment was the main barrier to e-government implementation (Kim et al., 2007; p. 351). Similarly, in Saudi Arabia, it was found to be one of the dominant factors influencing the use of e-commerce among financial services (Alwabel and Zairi, 2005; p..7).
