case/matter triage in forensic lab

What method do you use to triage, that is order the sequence of cases, in your work load?

What factors do you consider? do you have an "automated" rating tool?

Here are some of the factors that I use in my magic spreadsheet

Legal Hold issued
Active Legal Hold
Active Litigation
Internal Policy/Standards
Criminal activity
Public image
Executive involved
Compromise unprivileged
Compromise privileged
