It's not that easy for us marketers at times because we need time to understand all this information but once it has been done then there isn't much more info I can think off! Sometimes with omna its hard to explain in one sentence so sometimes people get frustrated which leads them away from using our product or service instead of staying longer than expected (which was never intended).
Also when someone leaves my team i have no idea where he/she went and if I am able to find him again after leaving etc..
