Our primary use cases are for portfolio planning, forecasting, budgeting, and obviously reporting. The project managers input for projects, input resources for proper forecasting, and for budgeting. It's the same with our resource managers to monitor their teams' capacity and then also for finance purposes for our annual budget planning.
We don't use the solution a lot for the project planning itself. As far as tasks and milestones, we don't use some of the features to see what stage a project is at. We really just use it to input the project. We actually use outside applications to manage a project in most cases.
As far as project planning, entering specific tasks and resources assigned to the project to forecast those projects is about all we use it for. And then, of course, start and finish dates. The flexibility to use a certain finish date is nice, but we don't really go into the project details in Enterprise One.
