I love that "Owner" is a mandatory field for all actions, but often there are multiple people who need to either a) do the same task, e.g. complete personality profiling tool, or b) contribute to someone elses task.
Using the RASCI model, owner would be the R, but there is no field for listing someone as an Support or Consult. This could be worth looking at.
