The populations of European societies are heterogeneous and a crucial part of effective crisis preparedness is to customize contingency planning and crisis communication to these populations. The aim of this study is therefore to develop a theoretically based model of organizations' crisis preparedness in heterogeneous societies. Through theoretical and empirical analyses the model for ‘Organizational Crisis Preparedness in Heterogeneous societies’, the OCPH model, is developed. The model provides a theoretical foundation for the understanding of organizational crisis preparedness and also has practical implications: It offers a tool with which to develop organizational contingency planning further. For authorities that supervise municipalities or other local authorities, the OCPH model can be used to analyse and evaluate organizations.
