Most quality and risk problems get caught after the cost is already locked in. The model's job is to move that moment earlier, so the team acts on a prediction instead of a postmortem.
The cost is already incurred by the time anyone notices.
The model predicts the trend and flags it while there's still time to act.
What decision this needs to improve, and how we will know it worked.
Whether there is enough signal, and whether it is the signal we think it is.
Build the model, test it against held-out data, check that it holds up.
Ship it into the real workflow, then watch how it performs.
