به کار گیری برنامه ریزی منابع سازمانی و عوامل تعیین کننده رضایت Enterprise resource planning adoption and satisfaction determinants

1. Introduction In an increasingly competitive globalized market, the key to organization’s success is the ability to maintain and increase that competitive advantage (Porter, 1991). In this new paradigm, organisations cannot compete on their own. Success can only be achieved through cooperation with other organisations like truly integrated and flexible supply chains (Lambert & Cooper, 2000). Enterprise Resource Planning (ERP) is a natural evolution of the 80’s manufacturing resource planning (MRP II), inheriting all the concepts and theories that date back to the 60’s with first attempts to rationalise lead times and possession stock costs. ERP rapidly became the standard enhancing operational efficiency with the integration of business processes throughout all organization (Akkermans, Bogerd, Yücesan, & van Wassenhove, 2003; Davenport, 1998). In the past decades, ERP systems’ usage numbers have increased tremendously, and the worldwide ERP market summed 22.4 billion euros by 2013. The competition is fierce, and the top five companies represent half of the market (SAP: 24%; Oracle: 12%; Sage: 6%; Infor: 6%, and Microsoft: 5%) (Pang, Dharmasthira, Eschinger, Brant, & Motoyoshi, 2013). After first failures of enterprise resource planning (ERP) systems in mid-1990’s, the IS research community became intrigued by the factors in such “productivity paradox” (Brynjolfsson, 1993). Making people adopt a new system was no easy process but is vital to the success of every organization (Basoglu, Daim, & Kerimoglu, 2007). Various studies were developed to understand the main drivers that led users to adopt a certain ERP system (e.g., Bradley, 2008; Chien & Tsaur, 2007; Gorla, Somers, & Wong, 2010; Nwankpa & Roumani, 2014; Nwankpa, 2015; Pan & Jang, 2008; Rajan & Baral, 2015; Sternad & Bobek, 2013; Tsai, Lee, Shen, & Lin, 2012; Youngberg, Olsen, & Hauser, 2009). Although the conclusions were very significant, reviewed studies are usually centred on a specific model or framework and fail to explain the relations between ERP user’s adoption and user’s satisfaction. Hence, through the review of scoped literature in the area, the state of the art about ERP Adoption and satisfaction is assessed. Founded on this review, a model proposal is built to have a structural body for validation. A survey is conducted to gather data, which is used as a base for model validation by the quantitative statistical method of PLS-SEM.
