We do have some power to stop the divisions we work with just buying whatever tools they fancy (see e.g. Department Y [nameless to protect the guilty], who demanded some shiny new CMS on the grounds that it would solve all their problems, were audited, and as a result were told that they were absolutely not allowed to buy any more shiny software until they'd sorted out the damn workflow that it was supposed to be supporting. Ha!)

The problem is, there are whole swathes of the university that we simply have no control over, and no one person (except possibly the V-C, who doesn't really get involved at that kind of level) has the power to impose any kind of consistent rules/guidelines across the board. Which is what the currently-in-progress Web Review is supposed to be addressing, but, well, yeah.
