Status Accounting on
inter-organizational
Service Management
Level
• IT Service Management Perspective
- Specification of inter-organizational IT Service Management (ITSM)
processes influences possible service states, e. g. io-Problem
Management -> State “problem”
- ITSM on intra- and inter-organizational level needs to be aligned
- Orientation on standards like ITIL or ISO 20000 could ease alignment
because of widespread international degree of familiarity
- FM could be modeled according ITIL for CDMB and io-CMDB
• Proposed Standards are developed “Stand-alone”, thus holistic integration
efforts necessary
• Emergence = complex patterns and systems might arise out of a
multiplicity of relatively simple interactions:
- Observable in inter-organizational service scenarios?
- Small cause might have large effect: root cause analysis has to be done
now inter-organizational
• MDR versus CMDB: replace or integrate decision for any MDR necessary
Open Issues
• To enable Status Accounting for hybrid cloud deployments corresponding
tools must enable modeling of organizations (OM), information and it’s
relationships (IM), communication (CM) and functional (FM) aspects

Status Accounting on inter-organizational
Service Management Level
• DMTF’s Virtualization Management (VMAN) standard
- Set of specifications for the management lifecycle of a virtual
environment.
- Open Virtualization Format (OVF): Standard format for
packaging and describing virtual machines and applications for
deployment across heterogeneous virtualization platforms
- VMAN profile: standardize many aspects of the operational
management of a heterogeneous virtualized environment
• DMTF’s Configuration Management Database Federation
(CMDBf) standards:
- Facilitates sharing of information between configuration
management databases (CMDBs) and other management
data repositories (MDRs)
- Enables to federate and access information from complex,
multi vendor infrastructures.
- Simplifies the process of managing related configuration data
stored in multiple CMDBs and MDRs
• UN/CEFACT’s Modeling Methodology (UMM)
- UN/CEFACT = United Nations Center for Trade Facilitation
and Electronic Business
- Information modeling of business requirements of inter-
organizational business processes
- Platform independent
- Core Components Library (CCL): Definition of reusable
building blocks

Challenges:
• Composition of services necessitates multiple different input types for each
service manager.
• Service Asset and Configuration Management for hybrid cloud services
requires Status Mapping both across organizations and across the different
service management levels.
Our Approach: Standards form the basis on all levels
Consolidated life cycle of service
parts:
- Inter-organizational (io) Service
Management Perspective
- Type of states depend on
specified io-Service
management processes, e. g. io-
Incident Management, io-
