Purpose: The purpose of this case report is to: (1) to describe outputs of a change project at Muenster University of Applied Sciences (Germany), which targeted its "operational core" of professors and (2) on this basis to derive ideas on how to ensure a high level of pervasion of change projects in the higher education sector. Design/methodology/approach: The author compiled data on the extent to which the project has penetrated the organisation derived from the project documentation, discusses satisfaction with the level of pervasion and presents four approaches to increase the level of organisational pervasion for similar projects. These were developed in introspective observations by the project team during project execution (2011-2021). Findings: The level of pervasion achieved by the project was judged to be satisfactory overall, but in principle still capable of being increased, as there are clear differences between subject disciplines. Four approaches to increase the level of pervasion are derived: (1) explicit attention to and monitoring of informal structures, (2) use of milieu-specific segmentation techniques of target groups, (3) variations of the way change objectives are presented within the organisation and (4) a dynamisation of stakeholder management. Practical implications: The paper offers guidance to change managers in higher education institutions on how to improve the planning phase of change projects. It is essential for change projects to achieve their intended outcome (project outcome) that the organisation is sufficiently pervaded in quantitative terms (project outputs). The recommendations presented in this paper should be of interest to all higher education staff involved in change management, as they can help to increase the level of organisational pervasion. Originality/value: Although Higher Education Institutions (HEIs) are considered to be a type of organisation that is difficult to change, change projects are an integral part of their management practice, follow one another at an increasing pace and are often being driven forward in a network of several parallel projects. This paper presents recommendations to increase the success of change projects in HEIs. In summary, the recommendations suggest breaking down organisation-wide change projects to the organisational meso level.
