System Software isn’t all that different from enterprise software. The business part is simply of technical nature. The biggest difference usually is that the software developers don’t have a deep understanding of the business rules.

I’ve had to maintain a bespoke compiler/IDE/VM for Windows Mobile/CE before and have spent two decades writing business software and architecting around the entire stack from networks, to databases, to web servers, load balancers, monitoring tools etc. I’ve also written SOWs, Done project plans, led teams (hated every minute of it). I’ve seen both sides. The types of optimizations and thought processes around enterprise software is completely different than the optimizations around compilers. The “entire stack” with enterprise software is much different than the “entire stack” with the compiler. I haven’t had a need to look at the assembly created from my compiler as a business software developer since around 2002. For context, my first hobby programming was in the 80s optimizing 65C02 programs by using zero page memory access to eke a little more speed out of the 1Mhz processor and trying to use branch statements instead of JMP statements because they were faster.

  Of course you’re not looking at generated assembly anymore because that is the business value of a compiler. The biggest difference now is that you’re probably not as big an expert in the enterprise topic as you were about generating assembly.

    These days - no. I’m nowhere near the business expert in the healthcare industry where I now work as I was in the ins and outs of assembly. That’s not my role. I’m a software developer by title, but I would consider myself an “expert” in both the software architecture and the AWS infrastructure of our (smallish) company. When I was working for the company where I did have to maintain the compiler/IDE/VM after they forced their founder out. I also had to know the complete business needs of the client that kept us afloat because as they laid off people, I had to interact with the customer and write the SOWs. I saw both sides. The skillset I needed to implement the business side was completely different than the skillset I had to have to maintain the compiler stack. Luckily I was mature enough (and an MBA dropout) to understand the business end and enough of a geek to understand low level computer concepts and could read assembly.
