Topic: Coalition Interoperability Organisational Interoperability: Evaluation and Further Development of the OIM Model

The military imperative to achieve increased interoperability both within forces and with other nations is well recognised. DSTO previously developed an Organisational Interoperability Maturity Model (OIM) to evaluate interoperability at the organisational level. The OIM considers the human-activity aspects of military operations, which are not covered in other models. This paper describes how the model has been used to identify problems and to conduct evaluations in coalition operations such as INTERFET and the Australia–US Interoperability Review. These assessments showed that the attributes of the OIM needed development and refinement. Further work on the model is presented. This model is then used to conduct a preliminary evaluation of interoperability between Australia and the US in the Multinational Limited Objective Experiment 2.
