Working at a place for 8 years -- through your 20s -- really shapes how you view the world, how you interact with people. I think about this more and more the further I get away from my time at Epic (I left in Jan 2023). There's some quirks I've noticed about myself as I venture into the outside world, double-edged swords. A few of the things I've been thinking about are below.
Speaking with certainty
We're trained to speak with our hospital customers with certainty and knowledge; better for someone to trust that everything you're saying is accurate, even if it means half your answers are "I'll get back to you." In healthcare, this works amazingly well -- it's a cornerstone of building long-lasting trust. Works less well in the real world / the investing world, where you can't possibly know everything and are rewarded for having an opinion.
Replaceability
Part of the Epic culture -- for better or for worse -- is that everyone is replaceable. My cynical take: the genesis culture of this is that turnover is/was high, so you need to ensure that if someone leaves, you can replace them. This works well when you have to travel to a customer site or go on vacation -- you can have real back-ups to replace you. A lot of energy thus goes into ensuring that other people can easily know what you're working on, into educating others on niche areas of the software, on building redundancy. In some investment firms (and in some governance structures), this replaceability -- a focus on process, on sharing -- is not a focus.
Deference
At Epic, we supported the hospital IT's team who supported end users (doctors, pharmacists, etc.) Thus, as Epic staff, my goal was always to make the end users trust the hospital IT team -- and ideally, never know that I existed (unless I came onsite). I would go out of my way to ensure that the hospital IT team looked like the heroes instead of me -- good for them, good for me. Same with newer team members: the quicker customers trusted the newbie, the quicker I could roll off; feeding the newbie answers was a win-win strategy. However good this may be for the org, the "leading from behind" strategy is not visible enough, especially when switching careers. It's a hard skill to unlearn.
"Build it yourself" mentality
Epic famously does not acquire; any tool you wanted, you had to build yourself. I feel the same way now -- I'd rather build a tool that works just how I want it than try to find a pre-existing software that does 80% and locks me in. A blessing and a curse.
