What is another name for enterprise systems?

Okay, so you want me to make this blurb about enterprise system names sound less like a textbook and more like... well, me talking about it, right? Let's give it a shot:

"Okay, so enterprise systems... another name for them? Ugh, honestly, these things! Why does everything have to have like, a million different names, right? Usually, when I'm talking about them, I just call them ERP systems. You know, for Enterprise Resource Planning? Makes sense, I guess, when you think about everything they're supposed to do!

But then, sometimes people call them just plain old "enterprise planning systems." Which... is kind of the same thing, maybe? And then, you've got your CRM systems - Customer Relationship Management, you know? - and I guess they sort of fit under the whole "enterprise" umbrella thing, but honestly? They always felt a little bit different to me. More focused, maybe? I don't know, is it just me? It's all just… kind of confusing, if you really stop and think about it, isn’t it? Like, back when I was working at [mention a previous job or industry], we had this ancient ERP system, and trying to get it to talk to our CRM was like...herding cats! A total nightmare! Maybe that's why I keep them separate in my head, haha."
