This paper has as its background, a practical enterprise change project where the Design and Engineering Methodology for Organizations (DEMO) was used in the initial stage as to give a neutral and concise but comprehensive view of the organization of a local government administration in the process of implementing an e-government project. The main contribution presented in this paper is an interview based qualitative validation of some of DEMO's axioms and claimed benefits – something that, to our knowledge has never been done up to now. Namely, we were able to validate DEMO's qualities of conciseness and comprehensiveness brought about by the transaction and distinction axioms and also the stability of its ontological models which are, by nature, highly abstracted from the human and technological means that implement and operate an organization.
