One of the worst things in today’s acronym laden world is terse explanations where jokes about TPS reports are at home. Nobody needs that. No one on your team needs to have their day spent deciphering gibberish. Acronyms serve a purpose, but any time you get a chance to explain a new concept avoid draping your explanation with a veil of confusion.
I had a manager once who quickly figured out (on his first day) that I was not familiar with his acronym cannon and switched to proper vocabulary and never switched back. It was glorious. I understood many of the acronyms in the industry, but he was new and came from a different background. His observation and flexibility made my understanding a lot easier and faster.
So explain things like your direct reports are five, even if they’re not, because that way it’s abundantly clear. And clear may deliver a better product.
