This isn't entirely the same domain, but I used to work on a lot of sites for the Dept for Education and the major problem is that people have awesome ideas for "engagement" and spend months or even years gathering support for funding.

It seems obvious to anyone working in tech that a site needs ongoing support, but it's not obvious to funding panels who sign off the 18 month funding plan.
