When managing tasks via email, tasks can bounce around from person to person, often with a limited sense of accountability or priority. In some companies, 20–30 % of these email tasks never get done. Sometimes this is OK if these tasks are of little consequence. But when important tasks are dropped, this can be a real problem.
By contrast, if all of your important tasks are initiated through ezCollaborator, they will never be simply dropped. They will remain open and assigned to a specific user until someone consciously closes them out or places them on hold.
