While the development of CRM started in the developed west, it has rapidly spread to developing countries. However, the way organisations adopt CRM in developing countries, and more specifically in the Arab world might be different and the context certainly differs. There is a shortage of rigorous studies that examine drivers of CRM adoption in this context. In this study we examine the antecedents of CRM adoption in the Jordanian service sector. The conceptual framework of this research is tested using a crosssectional survey of more than 322 practitioners. Using structural equation modelling analysis, results specify six underlying factors that explain CRM adoption: segmentation analysis, clear direction and objectives, performance measurement, rewarding usage, managing project changes, and knowledge management. Each area has implications for improving practices and maximising the benefits of adopting the process or management practice of CRM. This paper identifies key practices to provide useful guidelines for organisations in the Arab world making plans to adopt CRM, with broader implications for the adoption of many systems and projects there and for CRM deployment in developed regions.

This proves that CRM is a global concept (Ramaseshan et al., 2006). Nevertheless, most studies of CRM have either focused on Asia/Pacific markets (e.g. Lin et al. 2010; Wang and Feng 2012) or developed markets, such as North America (e.g. Krasnikov et al. 2009; Reimann et al. 2010) and Europe (e.g. Payne and Frow 2005; Rahimi et al. 2017). Findings from these studies are not easily comparable or applicable to companies in the Arab world, as different countries and regions represent varying practices and challenges to CRM (Ramaseshan et al. 2006). Hence, more research is needed to study the usage and implementation of CRM in developing markets, which are becoming increasingly important in their own right (Kumar et al. 2011). This study aims to determine the drivers or antecedents of CRM adoption in Jordan, an Arab developing country and to expand the understanding of CRM adoption and implementation per se.For many organisations, CRM has yet to deliver on its promises (Kim et al. 2012). The high failure rate of CRM projects suggests that researchers ought to provide business practitioners with better tools, which are useful for managing these projects (Forrester, "Map the way to your CRM business outcomes"). Industry studies have consistently emphasised that a lack of commitment to the core principles of CRM may explain why many organisations are disappointed by CRM implementation (Forrester, "Map the way to your CRM business outcomes"; Zahay et al. 2014). While there is a substantial body of literature concerning CRM and its adoption, research around this phenomenon is widely scattered and fragmented across different disciplines and perspectives (Gebert et al. ...
