Easy to stay up-to-date on tasks, notification emails are prompt and as a result, redundancy is eliminated in pinging people via email or chat. It's easy to attach documents to requests and create a unified view.
Doesn't seem engineered toward creative projects. I very much prefer the single view that Basecamp provides and the visual appeal of the Basecamp sign in page.
Consider the use case before considering Workfront as a one-size-fits-all product management solution for your company.
As a former user of both Basecamp and Trello, I required zero training to pick up either of these tools. Workfront requires, well, work to get up and running. I prefer a single view of a given task, but the fact that conversations can take place in both the documents and overview tab leads to confusion. Workfront is only as good as your team is at tagging you.
Workfront also requires you to be very, very organized to see utility from it. If a task is not nested properly under a project, for instance, it can be impossible to find. The search functionality helps in this instance, however, this does increase the amount of time spent digging instead of being productive.
On the other hand, the request format does allow for natural back-and-forth between our internal agency and those requesting a project. Trello is deficient in this instance, and is almost too flexible. I still love Trello for personal and team to-do lists, but recommend Basecamp over Workfront for creative collaboration.
