On the same day you have to decide the wording on the "Place order" button and whether order numbers in customer-facing URLs switch from sequential ids to random ones. How do you treat those two decisions differently?

Answer it out loud before you open anything. The value of the flags below is in comparing them to what you actually said.

The situation behind the question

Order confirmation URLs look like /orders/104233. Security raised that sequential ids leak order volume to competitors. Separately, the designer wants to test "Pay now" versus "Place order". Both are small tickets on the same board.

What it is really testing

Whether the candidate sizes the decision process to the cost of being wrong rather than to the size of the ticket. The button text can change in an afternoon; the URL format ends up in emails, bookmarks, support macros, carrier integrations and analytics, and changing it again is expensive.
