6.1 Conclusions
CRM has become a prominent topic among hospitality researchers and practitioners, given that maintaining lucrative customer relationships enhances business performance (Kim et al., 2006a; Wu and Lu, 2012). Chronological analysis revealed that the simple concept of RM as a marketing approach introduced by Berry (1983) has evolved into a multi-dimensional notion in hospitality. The thematic analysis identified five salient research themes that have received uneven attention in the literature; potential pitfalls and research gaps are identified and a framework is proposed. Previous research has assumed that CRM is superior over traditional marketing approaches, and empirical evidence has been lacking. Moreover, research attention on the negative aspects of CRM such as customer termination is missing in the scholarly conversation. Methodological diversification and innovation are necessary to investigate more complex issues related to CRM. The literature is still growing, and more effort is required to shift the focus from reinventing the wheel to initiating breakthroughs. This study starts off by offering a general overview of the existing literature and a roadmap for future studies.
