agencies have put forth visions of “prefilled applications” or “single sign-on services” that leverage the information an agency already has about its customers. But the number of agencies that have delivered on those visions is small, for the kinds of reasons I’ve already discussed, including lack of internal digital capacity, arcane and lengthy procurement processes, the many restrictive procedural requirements set forth in laws like the Computer Matching and Privacy Protection Act of 1988, and policy complexity that leads to thousands of formal requirements and doomed megaprojects.
