Everything we have written about this kitchen has been about a morning. This one is about a week, because not all of the work fits inside a day.
There are two kinds of jobs on the prep list. The first kind happens every morning without exception. Somebody wraps mochi before the doors open, seven days a week. The batched matcha and the batched hojicha get made every morning too, because what they make does not keep overnight. Nothing about the calendar moves those. They are on the list on a Monday and they are on the list on a Sunday.
The second kind keeps. A concentrate that holds for a week does not care which morning it was made on, only that it was made before it ran out. That is the work you can actually schedule, and scheduling it is the entire exercise.
Two facts set the shape. Saturday and Sunday are the two busiest days on the floor, and nobody running a Saturday counter should also be making a batch of ube concentrate. So Saturday and Sunday carry no batched work at all. Monday through Thursday are the making days.
That leaves Friday, and Friday used to be the problem. The next making day after Friday was Monday, so Friday reached across three days and inherited the whole weekend. Thursday, whose next making day was Friday, reached across one and inherited nothing. The heaviest day of the week sat directly in front of the two busiest days, which is exactly backwards.
The fix was to change which day does the reaching. Thursday now looks past Friday to Monday, four days out, and pulls the weekend's work onto itself. On the week of August 13th that took Thursday from four jobs to eight: ube, pandan, simple syrup and black sesame all moved onto it. Friday went from eight jobs to five.
Each of the five that stayed on Friday carries a printed reason. Already past date. Would expire before Monday. Must be made fresh daily. Low on stock at the last count. Nothing lands on a Friday because it is Friday's turn. It lands there because it could not wait, and on a week when none of it cannot wait, Friday is empty.
The rest of the week did not move: six jobs on Saturday, six on Sunday, nine on Monday including everything the weekend held. Four making days, two selling days, and one day that catches whatever the four missed.
If you want to talk to somebody rather than watch them work, come on a Friday.
