"Heuristic Tool List
Multitask Heuristics
D Performance, cost, and schedule cannot be specified independently. At least one of the three must depend on the others.**"
End description.
The first maintenance shop I worked in had a sign on the wall:
We do three kinds of jobs here
Good, Fast, and Cheap
Pick 2
This is in my textbook. It's the first sentence of the reading assignment. I am expired.
HOW MUCH OF THIS FUCKING CLASS IS GOING TO BE COMMON SENSE SHIT EXPRESSED IN ACADEMIC TERMS

Grogu knew how starships worked. They had engines or motors that created thrust. The thrust was aimed in a direction and the ship moved away from that direction. Simple, right? Wrong.
Starships were way more complicated than that. First, those engines/motors had to work hard. Really hard. They didn’t just carry themselves up into the atmosphere, but they carried the weight of the ship’s hull and all of its contents. And in Grogu’s experience the contents were always the problem.
First there was the equipment and control systems that were needed just so the engines worked. They didn’t just control themselves. Then they needed fuel. Starships used all sorts of energy conversion systems depending on what they did or were meant to do. Some of them were pretty straightforward.
A liquid fuel went through a controlled combustion chamber and the flame, fire, plasma, whatever, that was generated moved away from its point of origin because it was hot. Those molecules and atoms and sub-atomic particles did not want to stay where they were. So they moved one way and the thing attached to it went the other. Same for solid fuels, more or less. But importantly you had to store that fuel. It had to be somewhere. Unless you used ion sails or hydrogen scoops or stuff like that (the Force anyone?) you had to have your fuel on board.
That sounded pretty awful to Grogu. No wonder so many of the ships that tried to target the Razor Crest ended up looking like a tiny sun when they blew up. That fuel needed to be treated carefully. Almost delicately. But that is not what happened when laser cannons whomped on your ship. Nope.
Once you moved on from the fuel system (and who could blame you if you found it hard to move on), then you had navigational systems, gravity compensating systems, weapons systems, defense systems, communication systems, hyperdrive systems (a whole different problem with energy and fuel), and life support systems, just to name a few. That was a lot of systems so there was an OOS or Overall Operations System.
Grogu had almost forgotten about all the acronyms in use, like OOS. Those existed at the system level, the sub-system level, the object or assembly level (depending on the ship builder), the sub-assembly level, and the component level. He had once heard Din Djarin tell Peli that the NFCIR for the NFCISA, that fit into the NFICULA, and supported the NFCI in the Razor Crest was missing. Grogu had eaten his whole lunch and a snack while Din repeated all that when Peli looked up at him and said ‘I didn’t catch that’.
After that he just pretended that he didn’t understand what the Mandalorian was asking for until he said something like, ‘Hand me that 5 ohm resistor’. Grogu was happy to help when he actually understood what was going on. He had also made it clear to his friend and protector that when it was called ‘the RED one’ (resistor, electrical di-optic) he wasn’t going to touch it. Nope. Not making that mistake again (the resistor was in the end of that cable, ouch).
Grogu was baffled that once you crammed all that stuff on a ship it all had to survive contact with the enemy. People. All sorts of people ended up on starships. In his personal experience they could fall into two categories. Good people and bad people. The good people were great. They knew what they needed to do, they did it, and no one else was hurt, threatened or even mildly inconvenienced by them. Grogu mostly tried to be a good person when he was on a ship.
On the other hand the bad people required extra systems to manage their behaviors. Some of them ended up secured in a room of their own. That added a security system to the list of all the systems. Others had to be made cold. Very cold. That meant you had to have a carbonite system. Grogu had asked the Mandalorian if the carbonite system was a sub-system to the security system or if it was its own system, but his dad told him to drink his broth and Grogu did that instead, because someone seemed pretty cranky.
That might have been due to all the questions Grogu had about the food preserving and preparation systems. Grogu had asked Din Djarin why the Razor Crest didn’t have a food generator on board that could make good food, like frogs and shrimp and gorgs on a stick, but it did have a caf system. Considering that the caf system was offline at the time, the Mandalorian had been pretty annoyed. That may have been due to Grogu trying to program it to make him frog stew, but only ending up with broth. Oops.
A short time later they also had a long discussion about the waste management system on the ship. Or, to put it differently, Din Djarin had lectured him ad nauseam about the proper use of the privy and how to return it to a functional configuration.
Grogu had tried to explain that the privies on Coruscant, at the Jedi Temple, had a very different configuration and included a user interface that made it clear how to use the system in a step by step manner most appropriate for the species of the user and where they were in their life cycle. The Mandalorian must have turned off his auditory sensors because he just gave Grogu a look and ordered him to go to his hammock, pretty loudly.
While Grogu was laying back in the hammock he wondered about the other life support systems, like the air recycler and filters that kept in them in cool, comfortable, clean air. Well, mostly clean. The privy configuration issue had raised more than one kind of stink and Grogu was pretty sure that was the root of Din Djarin’s problems.
No matter how good a system was it couldn’t address every possible failure mode. This one certainly hadn’t been designed with Grogu in mind. Or maybe it needed a different systems manager. Grogu was happy to hand that job off to someone else. Anyone interested?

What do you study?
i study systems engineering and focus on human/computer interaction
basically, i make sure that the systems people use to help make decisions are actually usable - can the intended user make sense of the system's output or recommendations?

Balance
For System Builders / Maintainers:
Systems can be incredible at building stability and prosperity, but no system is perfect. Systems are constructed to increase the efficiency of normal operations / circumstances. There will always be outliers which need to be handled on an individual basis otherwise the system will become invidious.
For System Deconstructors / Rebels:
Systems serve the majority. Tearing down a system for the sake of an outlier often causes more harm than good. If that outlier wasn’t already a pariah, you can bet they will be when their demands come at the cost of others. Because of these considerations, it’s almost always better to work within the system than against it.
