This confusion about whether something is an issue or risk is a HUGE waste of time. It comes down to how one structured the event in one's mind. Are you focusing on the current problem being experienced or are you focused on the future? Are you being tactical or are you being strategic? Are you trying to cure the high blood pressure, the obesity, the high cholesterol, or are you trying to mitigate the heart attack and early death?
As you can clearly see, issues and the risks are linked. So where you log it and how you communicate it and how you work it all depends on where your focus is. If you are the leader, your focus is likely downstream, in the future, where strategy lives. Risk. If your a worker, your focus is likely here and now, getting to the end of the week, completing a task or sets of tasks. Issue.
But at the end of the day, where it is logged doesn't matter. What matters is you are mitigating the heart attack by curing the BP, obesity, cholesterol, etc.
