+The estimator is based on the following assumptions:
+- If the number of servicedesk employess is not sufficient, the number of open service requests will increase.
+- If new employees are added or new applications are introduced, the number of open service requests will increase.
+- If the documentation level is low, the number of open service requests will increase.
+- If the knowledge level of the service desk employees is low, the required time to process a service request will increase.
+- If the service desk employees have available time, they will increase the documentation level.
