This chapter explores the diverse models organizations use to guide their EX strategies. While these models aim to align stakeholders, increase direct investment, and ensure a consistent approach to EX, many are not rooted in academic literature. Conversely, models discussed in scholarly literature often lack translation into real-world practice. This chapter seeks to bridge that gap by synthesizing key theoretical and practical EX models, ultimately proposing an integrated, evidence-based model. The growing demand for evidence-based HR practices underscores the importance of developing a model that is both theoretically sound and applicable in practice.
