Finance Service Model

The IT manager models the Finance service in CA SOI as shown in the following graphic:

The Finance service has the following characteristics:

• It is a bottom-up service model arranged by domain. Logical groups represent the network, systems, and database resources.
• The service model uses logical groups to assemble CIs of the same type (for example, Application and Network Interface Cards) and create a logical, easy to understand representation of all resources.
• The service is modeled organically with no services imported from the source domain managers. If any of the source domain managers contained a service representation similar to one of the top-level groups, the IT manager could have imported that service and added it to the Finance service as a subservice.
• All CIs and groups use aggregate propagation, so that impact propagates directly from related items.
• Employees enter financial records using the Finance App and AccountRecorder applications. If these applications fail, the entire finance department cannot function. Therefore, the IT manager increased the significance of the application CIs from the default of 4 to 8. Because the FinanceServer hosts the applications, the significance of the FinanceServer CI has also been increased from the default of 5 to 9. These changes adjust the significance to reflect that the finance applications are the most important aspects of the Finance service, other than the supporting network.
