If I use a hammer to try to screw in a screw, was the hammer ill designed, or am I an idiot.
I current am teaching people how to use the entire Atlassian stack of tools, I always start off with a what is your process and lets see how the tool can help you, I get blank stares and get asked what all the tool can do and what problems it can solve for them. Without a process of how people interact and manage themselves JIRA and all tools are just a wonderful time suck to make it look like things are getting done and you are trying.
