The Cart Refill Memory Exception
The cart was assembled. The rice was not in it. The rice was discovered at the point when checkout was visible.
PROGRESS REPORT: CART REFILL MEMORY PROCEDURE Period: February 2021. Status: Active.
Background
The household moved its grocery procurement primarily online in April 2020. The transition was expected to reduce the cognitive load associated with shopping. The transition succeeded in removing the trip. It introduced the cart.
The cart must be rebuilt from memory every week. Memory is imperfect. Imperfect memory produces orders that arrive without one item the household needed and with one item the household already had.
Current Status
The cart refill memory procedure has been in operation since August 2020. The procedure involves: a kitchen walkthrough before opening the app, a list maintained in a notes application that is updated when items run low, and a checkout review pass during which the cart is assessed against the mental model of the kitchen.
This week's order included a checkout discovery: the household was low on lentils. The lentils were not in the cart. They were added at checkout. Two other items were added at the same point.
Cart Refill Memory Performance This Period
Week one: Two checkout additions. One forgotten. Item forgotten was cooking oil, which was discovered post-delivery. Week two: Zero checkout additions. One duplicate item ordered because a prior delivery was not unpacked fully before the new order was placed. Week three: Three checkout additions, all discovered during the checkout review pass.
The delivery saves a trip, but the order creates a second layer of monitoring and inventory work. This second layer has grown to include a notes application, a walkthrough ritual, and a review stage that adds approximately seven minutes to every order.
The Governing Rule
Once cart refill memory prevents one abandoned cart, it must remain in force for the rest of the routine. The procedure began after an order arrived without coffee. The absence of coffee created a problem that required a separate delivery or an in-person purchase. The cart refill memory procedure was adopted in response to this single event. It has governed every subsequent order.
Cart refill memory adds one extra decision to a routine that previously needed none. The new decision creates screenshots, notes, and walkthroughs that must also be managed. The supporting work outlives the original problem.
Consequence
A household member who does not primarily manage grocery orders has begun checking the notes application before suggesting meals for the week. They were not asked to do this. They adopted the behavior because the notes application was visible and its logic was clear.
Projected Status
The procedure will continue. A fourth stage, a post-delivery audit, is under consideration.
