This editorial is concerned with the need for an integrated approach to the design and engineering of organisations and their enterprises. Organisational Design originates from the organisational sciences, while the notion of Enterprise Engineering results from the engineering sciences (most notably information systems engineering, business (process) engineering, business process optimisation, and enterprise architecture). The Organisational Design and Enterprise Engineering journal (ODEE) is built on the premise that there should not be an either-or relation between Organisational Design and Enterprise Engineering, but rather an integrated approach that brings out the best of the two. A driver for the creation of the journal was the observation that the either-or mindset was (and still is) a major obstacle to the development of organisational thinking, and that this artificial divide must be abolished. In achieving more integration between Organisational Design and Enterprise Engineering, we suggest to take a model-enabled approach, where models should act as boundary objects between the social processes involved in organisational design processes, and the more analytical and rational side of enterprise engineering.
