Vera Meister (Jonas Jetschni): Development of a Semantic IT Service Catalog in a German Public Organization

  1. 1. Semantic IT Service Catalog in a German Public Organization Design, Development, and Implementation SEMANTiCs 2015, Vienna Vera G. Meister, Jonas Jetschni
  2. 2. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 2 Agenda  Initial Situation  Approach  IT Project  Success Criteria  Obstacles  Benefits  Next Steps  Demo Meister, Jetschni · Semantic IT Catalog in a German Public Organization
  3. 3. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 3 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 Meister, Jetschni · Semantic IT Catalog in a German Public Organization
  4. 4. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 4 IT Management Structure Meister, Jetschni · Semantic IT Catalog in a German Public Organization NOG Administration Lab Services DTE Lab Services DCS Lab Services DBM Head Head Library Data Center ChancellorPresident CIMC Center X before 2014 now Project Y CIO Panel
  5. 5. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 5 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 Meister, Jetschni · Semantic IT Catalog in a German Public Organization
  6. 6. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 6 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 Meister, Jetschni · Semantic IT Catalog in a German Public Organization
  7. 7. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 7 Use Cases and Requirements Meister, Jetschni · Semantic IT Catalog in a German Public Organization 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.

  9. 9. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 9 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) Meister, Jetschni · Semantic IT Catalog in a German Public Organization

Well … Oh no? Interesting … Navigation is totally confusing! That‘s exatly, what we are missing!
  14. 14. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 14 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 Meister, Jetschni · Semantic IT Catalog in a German Public Organization
  15. 15. SEMANTiCs 2015 · Vienna · 16.09.2015 Page 10/5/2015 15 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.
