Well you have to put context around what is being made more efficient.

Reducing headcount reduces labor costs and can be a form of financial efficiency. Reducing headcount also usually reduces the sheer number of people involved in any project, much like a small startup can move drastically quicker than a large, established org.

That said, there goal here doesn't seem to be clear as to what is being made efficient and they definitely aren't reducing the budget or size of government (outside of literal headcount, most people complain instead of red tape and regulations).
