First, “Functional Operating System," is the name I call it. Not sure anyone on the team calls it that.
It’s developed over-time with a “let’s have less tools and make sure everything has a place” mentality. I was involved with every aspect of the business, so personally I wanted to be able to lean in and operate the same way with all of my team who were doing different jobs.
At the same time standardization, efficiency, and valuing everyone’s time is important to me.
All that mixed together has had our team members be able to work the same across multiple teams. Everyone knows how to reach other members and what to expect in responses vs trying slack, email, text messages… to communicate.
So, to best answer your question it just happened organically.
