Agile and government do not mix
Using agile to deliver a government deliverable cannot work.
Procurement, finance, contract selection and deselection, etc are as waterfall as waterfall gets. Add to that the inevitable pre-election "what we have delivered" fixed dates and you get an environment where Agile has no logical function.
You can use agile as much as you like internally, but the actual shipment of stuff to gov (of any shape and form) and gov's side of planning the programme is not agile territory. It cannot be.
So the person to fall on its sword should not be the Agile consultancy, that should be the mandarin which decided to go all-buzzword compliant and run it as agile.
