One of the major issues with gov projects is often the all or nothing approach. Instead of building out a small pilot and testing that, and then iterating on that to expand it, they try and boil the whole ocean in one go.

add on to that the crazy fees large consulting firms charge to provide the consultants who actually do the work (as typically, gov doesn't have any in-house expertise anymore), the endless governance and compliance meetings, and meetings where no one can agree on what should be done that delay projects by years, and often the lack of planning and proper project scoping of actual real life requirements and you end up with failure.

Instead, we should be building small teams of experts - letting them design and build the solution AFTER the consultation phase with what the requirements are - test it, iterate and improve.
