On the Application we have a "Business environment" section with 2 fields.
Several customers told me that they need to manage additional information to describe an application or a service :
-Criticality (list of value)
-Notoriety impact (list of value)
-Maximum time out (duration)
-Confidentiality level / Sensitive data managed (list of value)
These fields are used for the request and incident management. According the value the priority calculation or the SLA can be updated.
