The other day, I had to look up the part number of a component that I knew existed, but that I didn’t know much anything else about. This happens quite frequently at the Shitshow because the products we make in aerospace (planes, rockets, satellites) are literally made up of hundreds of thousands of parts, each with their own unique part number. Of course, we have tens of thousands of engineers working on these individual parts, but like an assembly line, engineers are only familiar with the small amount of parts they are assigned to work on. So if you are working on the “nose antenna” and want to compare it to the “tail antenna”, but the only area you have ever worked on is the “nose”, then you have some work ahead of you to find the part. When I say “find a part”, I mean “find the part number” because once you have that you can find out everything else you need to know about it: what it looks like, who designed it, who makes it, what material it’s made out of, etc.
There are several methods to find a part.
Method 1 is called “Scavenger Hunt”. This is where you go from engineer to engineer seeking advice, following their leads until you find a person that actually knows the part number. The first guy you talk to, Engineer A, never knows anything, but he advises you to talk to Engineer B. Engineer B will also know nothing, but he will advise you to talk to Engineer C, and so on. By the time you talk to Engineer G, you will usually be able to figure out what the part number is. While it sounds simple, this method is the slowest because nobody is ever at their desk when you need them. (Approximate time to locate part number: 1.5 days)
Method 2 is called “Needle in the Haystack”. In this method, you can use a special computer program that can load every single part of the plane, satellite, etc. and show it to you in one big 3D model. While it sounds impressive that a program can show you hundreds of thousands of parts and how they all fit together, it totally hogs your computer’s memory. Even if you want to see just the “tail”, there’s still tens of thousands of parts that make up the tail. So loading a 3-D model of the “tail” on your computer can still take several hours. Once it does load, it is just a mess of intertwined parts that you have to sort through, clicking and hiding each one that is obstructing what you really want to find: that “tail antenna”. Once you find it, you can click on it and see the part number. (Approximate time to locate part number: 0.5 days)
Method 3 is called “Guess my name”. With this method, you do a series of searches in the Data Management System, a complex data management software system that essentially stores the definition of every part, product, system, and assembly in a “virtual vault.” (Think of it as a virtual filing cabinet that has the blueprints for every part and the instructions on how to put all the parts together to build the product.) The “Guess my name” method is exactly what is sounds like – you just start searching for terms in the Data Management System just as you would in Google. The only problem is this isn’t Google. It’s not user friendly and only searches for exact matches. And because the Shitshow never really came up with a proper method on how to name parts, engineers arbitrarily named the parts themselves. So you not only have to search for the term “tail antenna”, you also have to search for “tail antena”, “rear antenna”, “aft antenna”, “Tail Antenna” (because it’s case sensitive), “TAIL ANT” (because engineers like to use acronyms), etc. You get the picture. It’s a daunting task, but you can usually find what you’re looking for if you’re smart about it. (Approximate time to locate part number: 1-2 hours)
Because the best method of finding what you’re looking for at the Shitshow is to guess, I throw rocks.
