(ERP) software packages have become popular means for both large and medium-sized organizations to overcome the limitations of fragmented and incompatible legacy systems. ERP systems are designed as integrated sets of software modules linked to a common database, handling basic corporate functions such as finance, human resources, materials management, sales, and distribution. Most ERP packages also provide multiple language and currency capabilities, enabling integration of global operations. The popularity of ERP is documented in a study that showed that nearly 19 percent of organizations across all industry sectors have installed ERP software, with the manufacturing sector leading the trend. The study also showed that ERP's popularity continues to rise, with 34 percent of the surveyed organizations investigating, piloting, or implementing ERP packages. Davenport characterized ERP as "the most important development in the corporate use of information technology in the 1990s"

The insights in the book come from a series of research projects exploring enterprise architecture in more than 200 companies where our focus was on IT government from 1995 to 2005.

This paper reports on a comparative case study of 13 industrial firms that implemented an (ERP) system. It compares firms based on their dialectic leaming process. All firms had to overcome knowledge barriers of two types: those associated with the configuration of the ERP package, and those associated with the assimilation of new work processes. We found that both strong core teams and carefully managed consulting relationships addressed configuration knowledge barriers. User training that included both technical and business processes, along with a phased implementation approach, helped firms to overcome assimilation knowledge barriers. However, all firms in this study experienced ongoing concerns with assimilation knowledge barriers, and we observed two different approaches to address them. In a piecemeal approach, firms concentrated on the technology first and deferred consideration of process changes. In a concerted approach, both the technology and process changes were undertaken together. Although most respondents clearly stated a preference for either piecemeal or concerted change, all firms engaged in practices that reflected a combination of these approaches.
