Having been involved Operational Testing of software at DoD for longer than I care to remember there’s an old saying, “Nine women can not have a baby in a month”. There becomes a point where there’s no amount of resources you can throw at a problem to get it fixed any faster. Eventually they’ll see that is the case here.
The worst likely produce a net drag on the "team" and need to find another line of work where they might actually become productive.
Hadn’t heard that before....lol
