This 1000%. There's so much institutional friction with these projects for so many reasons; some of them political, some of them interpersonal, some of them just because someone doesn't want to. So many of these projects fail because people just don't want to work towards the goal, or simply do as little as possible and things move slower than molasses.
People don't want or care to change their processes. They do things that way because they've always done things that way. They see tools not as a way to get more done or be efficient, but as something that's "moving their cheese" and they don't like it. It doesn't matter how overworked they are by remedial tasks that could be automated, until you show them everything finished, end-to-end, working flawlessly, they won't be interested in the slightest.
The sad thing is that if there were some strong executive leadership behind these projects and they saw it as a positive thing, there could be better traction and better results. Instead, most execs look at these projects as mundane details and hand them off to whatever sad middle manager is going to take the heat for the project going south. The result is no teeth behind the initiative which even further exacerbates the issue of people not caring or lifting a finger.
