Service Model – Successful ITSM and ESM Modeling

Your Challenge

Many IT and enterprise service organizations face the challenge of clearly defining their services and unambiguously assigning responsibilities across different departments. Often, there is a lack of a holistic view of service configuration and the associated service assets. In addition, there is uncertainty about how to ensure consistent service quality and efficiently manage changes to the service portfolio—whether in IT, HR service management, or customer service management.

The Approach

The ITSM/ESM service model provides a blueprint that illustrates how service assets interact with customer assets to create real added value. It describes both the structure of the services and the dynamics of service delivery. By mapping configuration items (CIs) and their interactions, a transparent view of service quality as well as the underlying resources and activities is created. This establishes a solid foundation for specifically optimizing the service portfolio and clearly defining responsibilities—whether in IT service management or in areas such as HR service management and customer service management.

Our Services

• Phase 1: Initialization

During the initialization phase, the topic of service management is positioned within the broader context of the organization through a strategy workshop. This process fosters a shared understanding of the task at hand, identifies the necessary measures for achieving objectives, and develops a shared vision of the service model. In addition, procedures and documentation (e.g., templates) are established, information gathering is coordinated, the action plan is worked out in detail, and necessary training measures are defined. Finally, working methods and accompanying support measures are agreed upon to create a solid foundation for the implementation of ITSM and ESM initiatives.

• Phase 2: Identification

Based on the results from Phase 1, all necessary activities are carried out during the identification phase to identify the relevant services in the respective business units. To this end, existing descriptions of the business units are used and consolidated into a single service list. At the same time, IT services are identified in collaboration with the business units and aligned with the services. This results in a comprehensive overview that takes into account both IT services and enterprise services—such as those in HR, customer service, or facility management.

• Phase 3: Specification

The specification phase involves coordinating the method for specifying products and services. The content of the product and service specifications is determined, and the procedure for specification is defined. As part of the methodology transfer, the specification is carried out so that the specified products and services are created.

• Phase 4: Finalization

During the finalization phase, the functions are assigned to their respective services. A GAP analysis is conducted to compare service requirements with internal service delivery; necessary adjustments are identified and implemented. The result is a complete service model, which serves as the basis for the service catalog—a structured overview of all services offered that plays a central role in service delivery.

The Results

The ITSM/ESM service model provides a clear, holistic view of service delivery. This makes it possible to increase the efficiency of service delivery and make informed decisions about adjustments to the service portfolio. The detailed mapping of service assets and the interactions between the units involved makes service quality measurable and manageable. The result is an optimized service organization that better meets customer needs and clearly defines responsibilities—both in traditional IT service management and in areas such as HR service management or customer service management.
