@Bill Bennett86 probably the most consistent comment I've heard from everyone implementing EOS (big and small) is they didn't call out and directly address people issues as fast as they wish they did. If you're doing EOS, that means you want to grow and some people that were good for your past might not be good for your future. Those are tough conversations but everyone will be better off if you don't shield others from your expectations.
Other things I think are common for us little guys is not having mature data. Everything in our ERP system was cobbled together with duct tape and lack of clear data makes it hard to have good conversations.
Happy to hop on the phone to better understand your situation and offer what help I can. Email me if you want to chat sometime.
