The ERP system can be called as a system that integrates all information that runs through an organization (Davenport 1998) and can be termed as a large information system. This research adopts a definition of an information system that supports the basic concepts of what constitutes an ERP system. Valuable knowledge can be derived from existing literature on ERP System implementations.
There has been a call in the literature for significance of information systems research to practitioners (Heiskanen and Newman 1997) and (Benbasat and Zmud 1999; Lee 1999). In the back ground of the development and growth of ERP systems, Material Requirements Planning (MRP) systems grew to Manufacturing Resource Planning (MRPII) systems (Chung and Snyder 1999; 2000) and these systems later evolved to Enterprise Resource Planning (ERP) systems, a term that was given by Gartner Research Group in 1992 (Johnson 1999).
ERP systems are extremely integrated software packages (Holland et al. 1999) that can be modified to provide for the exact needs of an organization (Laberis 1999; Boudreau and Robey 2000; Estevez and Pastor 2001).
The definition that will be adopted for an ERP system within this research, is the following: `Enterprise Resource Planning (ERP), systems are big software packages (Gefen 2000) that offers the prospective to mix the total range of an organization's processes and functions in order to provide a holistic vision, a total solution, (Brown and Vessey 1999) of the business operations from a single information and IT architecture' (Davenport 1998; Davenport et al. 1998). Historically it is a fact that from the on set of this century, the ERP vendors (such as Baan, Oracle, SAP, J.D. Edwards and PeopleSoft), had begun to look at other industries (Piturro 1999) and increasing their on hand services, catering for little to middle enterprises and other similar industries than those characteristically implementing ERP systems. ERP vendors later developed to make their products in accordance with the requirement of public sector and fit educational set ups. (Nielsen, 2002)
Literature Available on ERP Implementations & Business aspects. There are large number of ERP outsourcing and systems that are being implemented worldwide and the scale of capital invested in these implementation projects, how ever does not match the research that has been published on the subject. Most of the literature has concentrated on project management and technical implementation issues (Brehm ET al.2001) as well as failures and successes (Willis and Willis-Brown 2002). The study is since to concentrate more on implementation and impact alone, much attention has not been paid to distracting issues.Similarly there it is an insufficient illustration to assess the financial savings that has been exhausted and will be used up in the ERP industry (Chang et al. 2001). This literature searched by ERP research taxonomy, along with the extensive review of ERP literature conducted by other authors failed to find any research topic that paid attention on factors separately.

Still, there is cynicism about and conflict to the idea of ERP application ...
