Creating the service model in BMC Atrium Core
The service modeling process helps you identify your business services and how those services are delivered and supported by your IT framework. While the process of creating your service model enables you to view your business services in the context of all your business processes, the service model is more useful if you use it to manage the impacts of events on your business services. For example, you can use the BMC Atrium Impact Simulator to determine how business services would be impacted by taking a server offline to upgrade software.
Using BMC Impact Solutions to create a service model
The applications that make up BMC Impact Solutions help you build and use a service model. Those tools also enable you to manage impacts of events on your business services. For example, the Service Catalog represents the service model as individual resources represented by component instances. A component instance is created through BMC Impact Model Designer as a single instance of a class that is defined in BMC Atrium Configuration Management Database (BMC Atrium CMDB). Classes can identify such physical components as servers or databases, and such logical components as user groups.
Whether you have implemented BMC Impact Solutions in your environment or not, BMC Atrium Impact Simulator and the Service Catalog offer additional ways to use your service model.
Deciding on the structure of the service model
How you organize service model components depends on the goals that your organization wants to attain through Service Impact Management, so determine those goals first. You can organize your service model components by using one of these basic organizational strategies:
- The business continuity and service availability strategy implements a business-centric model in which business processes and services rely on a small number of vital IT components to give a status overview of the underlying environment. This type of implementation is driven from the top, ensuring that IT is delivering their services as agreed. The driving force is business continuity and availability. This strategy is similar to the BMC Software BSM strategy that is called a Business Service Impact Model.
- The business-focused operational efficiency strategy creates a balanced representation of the operational environment, encompassing the IT components, such as systems and applications, and the logical components, such as services, user groups, and other business objects. This type of implementation is likely to involve various populations of management in the enterprise. The driving force is operational efficiency but with a balanced business perspective.
- The IT resource management strategy creates a thin layer of logical groupings on top of a large number of IT resources, ranging from applications and systems to hard disks and other hardware components. This type of implementation is run by and for the IT group. Services are just logical groupings that provide a convenient way of classifying the technical resources. The driving force behind this model is operational efficiency.
Although these strategies are only briefly outlined here, they are helpful in understanding that each implementation probably has a different focus, favoring some types of components and having more or less granularity in some branches of the component hierarchy. The strategy that you choose also affects the amount of time and effort required for its development and implementation.

Maintaining your service model dynamically
BMC Atrium CMDB has a dynamic service modeling feature that can automatically relate technical services in your Service Catalog to infrastructure configuration items (CIs), such as computer systems, that support them. BMC recommends that you take advantage of this feature to enable you to better manage your services.
