Thanks Skye!
I agree, historically Workfront was heavily focused on hour-based planning practices, but as the work evolves we also see ourselves needing to adapt to that reality. There are several approaches to the tracking effort we can take.
One popular one in Agile community is the system of points which is a more high level and has a larger margin of error but is also easier to set. Moving even more high level, there is T-shirt sizing - Large/Medium/Small which works fairly well for long-term planning practices. The highest level degree of estimations I've seen is purely counting tasks and calculating how many tasks can be done in a timeframe (and by tasks I don't mean Workfront object, just a unit of work). Ultimately, all boil down to analyzing historical trends and adjusting plans accordingly.
What we want to do is to take the minimal input from the users and instead leverage anonymized data from companies in the same industry, as well as historical data from the workers, to generate an estimate automatically. The first iteration of that is planned to launch with 20.4 and the first application will be Workload Balancer.
