One SIMPLE example:
In the State of California, circa 15 years ago, there was a 19-step process to procure anything bigger than a pencil. Of those, 16 were found to be about compliance (tie the bid in a red ribbon for goodness' sake!) and Non Value Added.
The steps involved 5 people. We used rethinking the process and technology to change it to a 3 step process (add 2 for approvals of very large procurements). The net was we were able to reduce the workforce -- THROUGH ATTRITION -- by about 20%.
This is one tiny example of hundreds (thousands?) of processes that evolved rather than were designed.
Sadly, that savings was just rolled up into bigger welfare benefits for illegals, but you get the idea.
Note: I have done similar things for local and federal government agencies.
Government CAN and SHOULD be run like a business.
