What does Asana do well? Asana allows you to visual a project and keep on task with reminders, deadlines and a Gantt Chart, among other features.
What does Asana not do well? I'm not sure. It's one of the best platforms I've ever used.
What do you wish you had known about Asana before using? Using Asana with a group makes project management easy and efficient. It works in a solo setting, too, however, it really blossoms with co-workers.
Have you used a competitor to Asana? If so, how does it compare? I've used Basecamp and Asana is so much better. Basecamp does the job but I do recall there were some limitations. Aside from those, Asana has a Gantt Chart feature that allows you to visually see your annual projects and functionally prepare yourself for each new day. If there is a snag, you can easily adjust future projects to accommodate the troubles of the present.
