Other states might want to do the same, although the fees would probably differ. So the idea is that 10 or 15 states cluster around one solution for a department, 20 for another, 10 for a third and the rest go their own way. The states would have a lot of power in being able to replace working solution A with B or C. So there's 3 or 4 DMV vendors, there's 3 or 4 unemployment vendors, some for contact tracing (my state of Oregon still hasn't implemented the Google/Apple tracing), and so on.
The current situation is that you know a potential replacement will be late and over budget, you just don't know exactly how bad it will be. And Accenture and IBM like it that way and are very adept at persuading the decision makers that they're very special snowflakes and can't use an off-the-shelf solution.
