@e66e934c The evidence about how, for example, DHBs, and local councils (and even ed institutions) have been divided and conquered by IT vendors, with each having very similar requirements to all their peers, but buying different, mutually incompatible proprietary tools. Look at things like the Auckland 'supercity' amalgamation - over $billion spent trying to 'rationalise' IT systems, and, far as I know, still a long way to go. Total disaster. 

 @e66e934c so I don't think it'd be too hard to make the case - based on the evidence of past failures - to suggest a totally different approach is required regardless of the conceits of council software architects. Ultimately, they don't matter nearly as much if everything they procure is open source/#LibreSoftware.
