As a manager of a team, I want to see the various projects that are owned by each team member to have a higher-level view of their situation/workload. I know asana allows this at a task level, but i would want a higher level summary view for projects by Owner. This will help greatly with project management.
If you have Business you could create a portfolio for each person (that requires manual work). You can also use my tool http://minimalist-work.com/asana/overview to see a list of projects with owner. No solution in Asana yet.
