Realist evaluation is a recommended approach to evaluate organisational interventions.

It examines how specific intervention mechanisms work in a given context to produce

certain outcomes through developing and testing Context-Mechanism-Outcome (CMO)

configurations. Inspired by realist evaluation, the five-phase model was developed by

Nielsen and Abildgaard (2013). However, this model (1) does not include some crucial

intervention components that should be evaluated in each intervention phase, and

(2) does not follow the full realist evaluation cycle. In this article, we address these

limitations of the five-phase model. First, we integrate the contents of the RE-AIM

framework into the five-phase model to include crucial intervention components.

Then, we explain how to follow a realist evaluation cycle, provide guidance on when,

why, and how to develop and test CMO configurations for intervention components,

and develop examples of CMO configurations for intervention components. In doing

so, we develop an Integrated Realist Evaluation Model for Organisational Interventions

(IREMOI). As such, this article demonstrates how working with CMO configurations

systematically in an intervention may improve the understanding of ‘what works for

whom in which circumstances’ and thereby the likelihood of intervention success.
