Creating on-boarding training discussing the nuances of different parts of the business. I use teachable now since it's powerful and inexpensive in my opinion at 99 bucks a month. I know this already sounds like a paid promo for them but It's not. I run a blood testing company and we have 150,000 customers who are keen on improving their lifestyle and health. I've been running digital operations since 2004. And I WISH i had been smart enough to document each tiny nuance, tip, how to and share it. Makes learning faster, keeps new team members engaged and happy since they are more comfortable they are in turn less likely to quit, and you don't have to hold everyones hand as much or at all. I could write a book on other things. but 1 other massive improvement was selecting mission critical stats to come inbound to me automatically in slack. i.e. site down, checkout errors, sales revenue comparable to previous period, customer tickets, i never have to go look for it. I connected it all to slack in one way or another and i see it first thing each morning. It helps me spot issues before they become big problems and it feels like i can see around corners because you get the pulse of the business.

Hope this helps. if you need some more help just email me jp AT jean-pierre.com

fun fact: This is my first real comment in Hacker News, I figured after seeing so many articles that helped me over the years, I'd give back. Thank you Hacker News and Y Combinator for all the great stuff over the years.
