Default permission For All groups and Users in Incident Management

Hi All,

Can any one guide me where to Modify permissions on assigned groups and users in Servicedesk 7.5 sp1/sp2.

for Servicedek 7.1 sp2 its location is 

Project: SD.IncidentManagement

Model: Initial Diagnosis

Specific Location: Initial Diagnosis DW, Event Configuration Start Process

but in Servicedesk 7.5 I am unable to find the Initial Diagnosis Model 

where I can modify these permissions on groups and users in Servicedesk 7.5 / 7.5 sp1/ 7.5 sp2

regards
