This is what I mean by “context at the front end.” David’s instruction to imagine explaining your purchases to your bosses is not a simple exercise in make-believe. If you aren’t careful with your spending, you likely WILL have to explain your purchases. At Netflix you don’t have to complete a purchase order and wait for approval to buy something. You just buy it, take a photo of the receipt, and submit it directly for reimbursement. But that doesn’t mean no one pays attention to what you spend.
