Life of a job
A simple job follows the stages:Log => Accept => Assign => Resolve => Close
(with some time entries attached along the way)
A more complex job may also have some stages repeated or have another stages such as:Reject, Unassign, On Hold, Un-resolve, Re-open
At each stage the details can be emailed to any person involved (ie. The originator, the person resolving it, closing it, interested third parties etc).
