Locally in our country, we use BMC Remedy Help Desk Express with SLA capabilities and the "Management Center" module for better reporting/dashboards. The purpose of Remedy is to support many clients in a cloud/managed service setup with a Customer login available also. (I am in the architecture group here and not in the servicedesk group and so am not Remedy or OTRS experienced, I want to take a neutral approach to this)
I'm doing an initial evaluation of OTRS. OTRS is used at a corporate level for our internal helpdesk only and it may make sense to migrate to it locally in the managed service space. The following are the higher priority areas in the requirements (or concerns) as to whether OTRS can meet the needs, your help is greatly appreciated:
1) Is it suitable for multi-Client managed services with dedicated, segregated organisations, sub-organisations/projects within each client with a dedicated portal for each client ?
2) Assuming there is customisable workflow, can you setup SLA's per Client, e.g. Priority 1,2,3,4, expiration notifications on tickets, Level 1,2,3,4 support structures ?
3) Can you have pie chart, bar chart/other refreshable ticketing information for display to the helpdesk staff (for display "on the office wall" so to speak). Does it meet SDE Management Center capabilities do you think ?
4) Can you produce PDF weekly reports for each client ?
5) Do the notification options equal or surpass Remedy SDE e.g. changing between Priorities of a ticket, can the client be notified ?
6) Is resolution a concept and do "resolutions" become categorised and/or is there a good "knowledge base" built with search engine capability ?
7) Can you attach documents to a case/ticket ?

many thanks for any assistance, Tony.
