if this is true, then would it be a better investment to have the 2nd team produce a fuzz testing/systematic testing mechanism instead of producing a secondary copy of the same system?
In fact, make it adversarial testing such that this team is rewarded (may be financially) if mistakes or problems are found from the 1st team's program.
the whole point is that they're not collaborating so as to avoid cross-contamination. also you don't get paid unless and until you identify the mistake. if you decrease the reward over time, there is an additional incentive to not sit on the information
