What's the 'opposite' of mise en place?

Mise en place definition for those unaware.

Mise en place (French pronunciation: ​[mi zɑ̃ ˈplas]) is a French culinary phrase which means "putting in place" or "everything in its place". It refers to the setup required before cooking, and is often used in professional kitchens to refer to organizing and arranging the ingredients…
The practice can be applied in home kitchens.

My google-fu fails me on this. Dictionaries tell me what it is, but it has no antonym.
The idea cropped up as I was …ermm ‘mentioning’ that my partner’s anticipated meal-time would be easier to hit precisely if everything was ready-prepped leaving only the actual cooking (I’d secretly estimated her dinner time would be half an hour later than she thought… shhh, she’s now prepping it all in advance after some small discussion;) I then wondered what you would call my more common method of ‘just in time’ prep.

Depending on the dish I’m making I will either do a full mise en place, everything prepped & ready to go, or I will run a ‘just in time’ process where each ingredient is prepped just in time for it to be needed, eg prepping onions after rice goes on, then chopping the tomatoes whilst the onions are sautéing. Salad prep after everything hot is on the boil etc. Everything comes together only at the very end, at plating.

Is there a specific term for this ‘just in time’ prep?
