It reminds me a lot of dev teams creating a microservice and giving it a code name. Imagine someone from business joining standup and hearing a bunch of microservice code names and acronyms. They would be really confused! Maybe the same thing is happening here to you?
The second thing you mentioned is their explanation about Robert Smith etc. You came out more confused after the explanation! To use the same standup example: the business person asks in your standup what does the “Odin” micro service do? It might be quite hard to explain what a single microservice does to someone without prior experience in that field.
Long story short: the best way you can get an understanding for what they’re talking about is to build a background in it. Feed your curiosity! Read a good intro book on business or economics to get a good foundation. See if you can setup some kind of regular 1:1 with a business person over lunch to learn more, etc.
