New Information Systems Development Methodologies (ISDMs) are suggested in the belief that their deployment would be beneficial to consultants in their work. A large number of ISDMs already exist but their value has been questioned and at the same time new methodologies continue to be introduced in an attempt to support and improve the practice of information systems development work. What is not always clear from current studies is that ISDM is a multi-perspective and cross-discipline phenomenon. Although a large amount of knowledge of ISDM is available, different disciplinary interests have resulted in fragmented assessments of it. This paper intends to identify theoretical perspectives applied in the conceptualization of ISDM. A review of the literature on ISDM was conducted and four different theoretical perspectives were identified: 1) system, 2) structure, 3) innovation, and 4) knowledge. While each perspective provides various overarching depictions of ISDM, the synthesized view of ISDM provided in this study reveals the complexities and ambiguities of a multifaceted phenomenon such as ISDM. Suggestions for an alternative conceptualization of ISDM are provided in an attempt to facilitate the investigation of ISDM

This chapter introduces the key factors that motivate Small and Medium Sized Enterprises (SMEs) to select Open Source ERP (OS ERP) over the proprietary ERP. The chapter starts with the related previous research works by stating the basic concepts of OS ERP selection. The goal of this chapter is to empirically identify the most important factors that may motivate the Small and Medium Sized Enterprises (SMEs) to select this category of enterprise systems. Therefore this chapter proposes a Theoretical Model for Open Source ERP selection by SMEs and later on conducts an empirical study based on that theoretical model. The chapter tries to broaden the discussion around the important selection factors by including the perspective of the suppliers along with the perspective of OS ERP implementer SMEs.
