Doesn't matter if it's cutlery, bits, people, or shit. Your company's biggest problem is probably ensuring the right stuff is in the right place at the right time, while also ensuring the 7 other combinations of right/wrong stuff/place/time don't happen.
But most companies don't realize that. They try to frame logistical problems as business problems and try to have fresh MBAs solve it. Half of all startups are some guy trying to solve a general logistical problem for a specialized audience using the cloud.
Old guy at my old job. Retired Navy Chief. Never seen him smoke, but can't imagine him without a cigar in his mouth. His saying was "The important part is getting the logistics right. Everything else is logistics."
When you tame that chaos, and it's saturday afternoon when all the best people are there and everyone is on their game... I've never experienced anything like it. It's like when you see a really amazing play in your favorite sport, but that same amazing play goes on for a couple hours. I imagine it's like being an air traffic controller or maybe a stock broker on the trading floor where you can talk to everyone and it's productive chaos at its glorious peak.
I also remember working the order taking window and getting into the flow of quickly finding the items after you master the educational part. In a way it's like lego-building or very simple programming.
It's amazing, but it's also a bit distracting. Thankfully, as you're coming down off that high the music often comes down too, and it guides your emotions back into a calm flow, ready to build up for the next release.
I sometimes write code at the rhythm of those songs, and it’s amazing for my productivity.
Been crew trainer in a german company store next to an exit of several Autobahn crossings, doing mostly late/night-shifts around 1989/1990. Was some sort of internal flagship store because all managers of the area met there often. And we trained the 'franchisies' opening their own. And the f.... "Blitzcontrols". Always found something. Never got 100 points, only 98 or 99. GRRRR!
The pay was amazing btw. because at that time late/night work got huge bonus mandatory by law. About 4800,- Deutsche Mark every month. Nowadays not anymore.
Anyways, when several busses arrive at once because of some soccer games you have to 'flow' in sync with everybody else. We did. And had fun while doing so.
Depends whether someone gets to just fill the shelf as per plan or has the curiosity to ask "WHY", noticing why X things fly off the shelf why Y things two shelves lower stay there forever. This curiosity builds the critical thinking 'muscle' and can motivate a shelf-filler to switch into marketing (hypothetical scenario has to do with a 17yo working part time and then deciding to studio marketing)(I didn't study marketing) :)
I'm sure you could measure it financially, and that a nicely done shelf stock makes more money than a poorly done one.
That being said there are a lot of jobs where I have difficulty imagining what mastery looks like; say in an automated, low choice style field like bus driving. I couldn't recognise an expert bus driver from a relative novice. But that probably only reflects my lack of knowledge about bus driving.
But a lot of it is just for show. Not really that impact-full on the work done.
People do it because they get a sense of achievement out of it.
But isn't the psychological sense of achievement suppose to be a reward for completing meaningful goals ? Isn't this "empty calories" in a sense ?
Look up "Bus Rodeo". It's basically a skills challenge for bus drivers.
You'll see drivers make maneuvers with 60 foot articulated beasts that the average person would have trouble doing in a normal SUV.
It was the job I have been most satisfied with in my working life. However, I did only do it for 8 months for 6 hours a day. Maybe in the long run it gets more boring.
The variety between shelf filling between different store brands and even different stores of the same brand made me really think no two jobs are the same.
Not my field, but perhaps you need to widen your view a little.
I'll bet there was someone at your store who was the Shiva of Stacking too?
I only worked checkouts (pre barcode scanning, other stores had it).
