The Third Promo Incident
Decide what you would do from the brief alone. Everything below it is available, but the exercise stops working if you open it first.
The situation you were handed
Your manager: "That is the third checkout incident this quarter caused by the promotions code. Write the postmortem and let's put it behind us. Also, the team wants a rewrite — can you put that in as the main action item?"
The trap — the move that looks right
Putting "rewrite the promotions service" as the main action item. It feels decisive and matches what the team wants, but it cannot start for months, the cheap fixes that would prevent the next incident are pushed behind it, and when the fourth incident arrives the postmortem will say "rewrite in progress".
