We have just rolled out Asana to our team for content management, workflow and calendar. The biggest flaw for us is that anyone that is a member of our group can add, delete, change anything at any time. We need some members to be “view (or read) only,” where they can see all the activity around tasks and the calendar, some to be “editors” for certain projects, etc. Even though we have asked people not to change certain things, once they had access they did by accident. This feature is very common is platforms like Dropbox, Google sheets/calendars and others where multiple people access the same content. I almost considered this a fatal flaw to not use Asana at all, but decided to give it a try.
