Just in Time vs Just in Case

Just in Time (JIT) and Just in Case (JIC) are phrases used in logistics,  especially for manufacturing. JIT wants the products to arrive just in time,  as needed,  meaning less costs for storage and more streamlining.   JIC,  wants the products sitting there waiting,  just in case of need,  where you pay more because you have them longer before using them,  but you have built in protection if something goes wrong. 

I am so a Just in Case kind of gal.  I think all mothers are - you take an extra change of clothing - just in case it's needed.  Yes your carry bag is bigger,  but you are relaxed and carefree because even if there is a huge unexpected throw-up,  you're covered.

It also worked for me really well during Covid,  because I actually did have 2 of those enormous packs of toilet paper hiding the in the cupboard (they are so much cheaper when you buy them that way, and they can't go off,  why not have two lots of 48 toilet rolls?) 

My pantry is full of weird jars and cans,  but it means we never run out of staples and can bake a hummingbird cake any day of the week (oil based rather than butter,  so you really can make it solely from pantry products.)

I don't think one is better than the other, though the logistics world is definitely selling Just In Time as the savvier option. I think one may suit your personality more than the other.  I couldn't force myself to be a just in time person,  I would be stressed and anxious.  And I don't mind over packing (I had friends tell me with great pride that they flew to Europe for 2 weeks with only carry on luggage,  and I just thought - why,  why was that even a goal?) 

So using that other great phrase - your mileage may vary (ymmv) let yourself work within the system that suits you best!
