Initial Situation
IT Operations and IT Management
 in our university
 homegrown
 heterogenious
 primarily focused on technical aspects
 rather reactive than proactive
 similar situation in a majority of public organizations
 lack of transparency and guidance for
 users
 IT staff
 executives

Service Orientation
As of now
• no service orientation
• no clear picture about IT services
• support at technical level is basically well organized, but under pressure
• user support follows the „Hey Joe“ principle
• necessity of broad technological know how at all organizational levels
• at the same time: redundant services to some extent
Decision of the CIO panel (January 2015)
• stepwise implementation of service orientation
• priority No 1: implementation of an IT service catalog
• provide at least a central information base

Approach
1. Requirements Analysis
 Collection of use cases, requirements, and competence questions
2. Subject and Field Research
 IT service catalog implementations in German public organizations
 Structure and general requirements on IT service catalogs
3. Evaluation of Implementation Types
 Analytical Hierarchy Process based on core general requirements
4. Data Collection
 Media analysis, inquiry, and observation
5. Prototyping

Use Cases and Requirements
want to have guidance on public IT services at university
 e. g. as prospect students, as potential project
partners of the university etc.
need information about a specific IT service
 e. g. about access conditions, service options,
support offerings, operational processes etc.
aim on central coordination and standardization of services
 e. g. for efficient appointment of scarce
resources, for
optimal support for IT management processes etc.
need reliable data about costs and expenses of IT services
 e. g. for budget planning, for implementing an
internal transfer pricing system for shared IT
services etc.

IT Project
1. Selection of Tools, Standards, and Frameworks
 ontology editors, basic ontologies and vocabularies, code libraries
2. Ontology Engineering
 as fare as possible based on standards, streamlined structure
3. System Design
 simple prototyping with multiple options for extensions
4. Application Development
 based on web technologies: HTML5, CSS3, JavaScript, PHP
5. Evaluation
 based on personal discussions, inquiry schedule, and observation (N=25)

Ontology Editors
Systems Tested
 CMap Tools
 Knowledge Builder
 PoolParty
 rdfEditor
 Protégé
 WebProtégé
 OWLGrEd
 None of the tools meets all requirements
 Selection of a tool set: rdfEditor, Protégé, and WebProtégé
Requirements
1) Structured coding
2) Syntax checking
3) Support of standards
4) Ontology „mashup“
5) Easy reengineering
6) Structure and Graph visualization
7) Support of cooperative work

Success Criteria and Obstacles
Success Criteria
• Joint expertise of the core developers (subject + semantic technology)
• Time for growing
• Top management’s buy in
• Enthusiasm and doggedness
• Flexible technical support by administrative staff
Obstacles
• Shortage of human resources
• Blockers in the CIO panel
• Weak tool support for ontology merging
• Weak standard vocabulary support

Benefits
Appreciated by Evaluators
 Chancellor: Reports allow better control of the organization,
e. g. in terms of review of contracts with extern providers.
 Professor + Case worker: It may be very helpful during onboarding.
 Head of Lab Services: We could implement our ticket system for all
users.
 Controler: We could check the involvement of staff into IT services
and allocate costs according to the cost-by-cause principle.
 Student: It‘s nice to have all services for students in one place.
Intended by CIO Panel
 More streamlined IT service supply,
 Data basis for IT-related financial and organizational decisions,
 Central information point and access point for service support.

Next Steps
 Content development
 Functional enhancement
 Faceted search and filtering
 Visualization of relations between services
 Login and target-group-specific presentation
 Semantic server with more functionality and performance
 Ontology enhancement/upgrading
 Connection to other systems (monitoring, CMS, DMS)
 Implementation of REST API
 Further deployment in the federal state Brandenburg
