Reply to comment by kingofzdom in Eli5: On a production line, how do they make a car, plane or anything else be identical from one another without differences? by SideburnG
Must’ve take a lot skill to do things correctl, but what happens to the workers that get it wrong?

They get fired, face a civil lawsuit at the absolute worst.

Only if you want your company to fail horribly.
If the process doesn't work right, you fix the process. Someone figures out what went wrong, and they figure out a better way of doing the task, and then that specific problem doesn't happen any more.
Firing people for making mistakes is an effective way to get people to hide mistakes, push blame on others, and otherwise make problems much worse.
There's a management joke: A worker who just caused a million-dollar failure is called into the manager's office. Worker says, "Well, I guess you're going to fire me." Manager laughs and says, "Fire you? We just spent a million dollars training you!"

Better way can also include stuff like https://en.wikipedia.org/wiki/Poka-yoke to make it more resistant to human errors.
Like if you have part A1, A2, and A3 that all can go into square hole B, but you actually want them to go through corresponding holes B, C, and D, then you could make it so it is physically impossible to put them all through the square hole.
An everyday example would be electrical connectors with different sized blades, or that can only be connected in a certain orientation because they aren't symmetrical.

One formulation of Murphy's Law: "If there's more than one way to do a task, and one of those ways will lead to disaster, someone will do it that way."
Running this backwards: If you don't want someone to cause a disaster, you make it impossible to do the task that way.

We live near the Intel fabrication plant. They have a thing called "The Million Dollar Mistake" where a fab tech will drop the freshly cured silicon sheet for making microchips. Its about a million dollars worth of potential product and EVERY EMPLOYEE has dropped it at some point.

That sheet is called “wafer”, cut from a monosilicon ingot, costs maybe 10-20 bucks. Ok, more if it was processed, but come on! It is like saying you are a mass murderer if you jerk off.

That's all well and good when you're manufacturing consumer goods
I'm specifically talking about aircraft manufacturing. Someone fucks up, people die. Investigations happen. Fingers are pointed. Someone gets fired, minimum.

Thats a large chunk of my job.
I'm a process improvement specialist.
​
My role is to observe existing processes for loopholes and bottlenecks, and identify areas of improvement.
I think create the solutions, or a new process entirely and train the teams on how to use it.
Many companies don't invest in Process optimization, though they should.
You'll be amazed at how clunky the resources allocation process is, and how much it costs the company in tech debt and money.
My main goal is make a process as efficient as possible, so that in the long run, it will save the company time and money.
