Right now Planner is very limited as an enterprise solution. Every plan/project is in its own silo and one can't manage resources, tasks or projects outside of a small team. The following features would be a big step forward in terms of enterprise capability:
- Resource management across multiple projects. As a minimum it should be possible to view the Assignments and Charts tabs across a whole group, not just a single plan. Similar for People and Goals tabs would also be useful.
- Task dependencies between different projects
- Task requests into a project, allowing outside the project team to make a request that the Project Manager needs to accept
- Allowing a task to be in more than one project (could be similar to the above)
Other items that would be helpful:
- "Sticky" views, with the current state of filters, group by, zoom, date range etc retained between sessions
- Bulk update of tasks
- Moving tasks between projects
- Keeping effort constant when duration of a task is changed
- Allowing top-level tasks to connect to Goals
