NATO’s Concept Development and Experimentation approach in the EU’s Common Security and Defence Policy? – an institutional isomorphism perspective

ABSTRACT The paper analyses the Concept Development and Experimentation (CD&E) approach which has been developed and implemented in NATO over the last 20 years. NATO’s CD&E approach is explained as an organisational innovation and institutional response to external and internal pressures. Within the theoretical framing of institutional isomorphism, the paper analyses the adoption of CD&E in the European Union’s (EU) Common Security and Defence Policy (CSDP). The research hypothesis is that the EU will adopt and apply NATO’s CD&E approach in the EU’s defence planning and capability development process. The empirical findings from the analysis of the EU policy practice, however, show that CD&E has actually been adopted from NATO and applied by the EU to a very limited extent. The low degree of isomorphism between NATO and the EU with regard to applying CD&E is explained by a complex set of factors. The research results have broader implications, suggesting that under the current institutional settings it is highly unlikely CD&E to be adopted by other international organisations in the field of international security.
