Something which is often overlooked by agencies (including myself) is the need to constantly reviewing processes.
Over time (ESPECIALLY IN THE EARLY STAGES) things change.
It may be variations in your service offering, how you onboard people, who completes a certain task or even what software you use.
All these little changes over a longer period of time will make older SOPs or process breakdowns useles if you don't decidicate time to review them on a regular basis.
This is something which I need to personally hold my team accountable for because things change a lot and if we aren't able to maintain what we build out then there is little long term value to dedicating the resources to break them down in the first place!
Take 30min to 1 hour this weekend to look over any SOPs or documentation you have and ammend it according to any cahnges you've made since you last created it.
Don't be that guy that creates something and never looks at it again🤣
