Before a model advances from testing to production, its lifecycle governance workflow must require something specific. What is it?
Select an answer to reveal the explanation.
Short Explanation
Testing tells you the code works. It doesn't tell you the risk and controls picture is right for production. You need a documented review and formal sign-off before the model moves.
Full Explanation
The correct answer is the documented review of risk and controls appropriate to that stage, concluding in a formal sign-off. The testing-to-production transition is exactly the kind of key stage lifecycle governance targets, because it is where a model's exposure and consequences of failure typically increase.
The passing result on the test suite alone is incorrect because a passing test suite reflects functional correctness, not risk or control readiness.
The verbal confirmation from the testing team that nothing looked unusual is incorrect because an informal verbal check leaves no reviewable record.
The nothing additional, if the model previously passed review at the proof-of-concept stage, is incorrect because a proof-of-concept review was scoped to an earlier, lower-stakes stage and does not cover production readiness.
For the exam, expect a documented risk-and-controls review with sign-off at each stage transition, including this one.
