    • Value model ontologyfor service systemsGeert PoelsGhent University, Belgiumpag. 1NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poels
    • Summary: definition/origin of concepts• value model (Enterprise/IS Engineering)• value model ontology (Applied Ontology)• value model ontology for service systems(Service Science / S-D Logic).. for modelling enterprises as service systementities that purposefully interact in mutuallybeneficial service exchangesNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 2
    • NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 3Value models help in conceiving, designing, engineering andmanaging business entitiesExamples of potential applications of service system value modelsand information systems based on these models:1. Value/cost management (costing, pricing, valuing)2. Resource/inventory management (inventory levels, sourcing)3. Capacity management (usage/occupancy rates)4. Performance management (service times, monitoring & control)5. Quality management (service/waiting times, tracking & tracing,accountability)6. Strategy & business model / service innovation (designing serviceofferings & value propositions, profitability analysis)
    • 1. Purpose• Service Science: few research on service systemmodelling• Enterprise/IS Engineering: much research onvalue modelling, but current approaches assumea ‘goods-dominant’ worldview• Purpose = design new value model ontology thatontologically commits to S-D LogicNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 4
    • 2. Design/Methodology/Approach• Design Science Research Methodology(Design Science)1. Problem identification and motivation2. Define solution objectives3. Design and development4. Demonstration5. Evaluation6. Communication• Theoretical basis: Resource-Event-Agentontology (Accounting)NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 5
    • 3. FindingsDesign artefact: Resource-Service-System ontology• S-D Logic interpretation of the REA ontology• Fromconceptual model of economic exchangetoconceptual model of service exchangeNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 6
    • UML class diagram of core REA elements• Service as endurant (object) instead of perdurant (process)• Value (embedded in economic resources) is produced/provided(economic event) and consumed/received (economic event)NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 7
    • UML class diagram of core RSS elements• REA economic event = RSS service• REA economic agent = RSS service system entity• REA economic resource = RSS / SDL resourceNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 8
    • NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 9Service process view based on ISPAR model
    • 4. Research limitations/implications• Explicit specification of shared conceptualization• Difficult to prove, although..• ..concepts and relations were defined in accordance withservice system worldview and ISPAR model(Spohrer, Maglio, Kwan, ..)• Future research:• From conceptual model to computational ontology• Design modelling notation and method, and develop toolsupportNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 10
    • 5. Practical implications• Explore applications of service system valuemodels for SSMED• Revealing, analysing, reasoning about• Teleological/ontological nature of enterprise servicesystem entities (i.e., function and composition)• Internal operations (i.e., resource allocation andorchestration of service processes)• Externalized behaviour (i.e., choreography of serviceinteractions)NFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 11
    • 6. Originality/Value• Contribution: ontology for the value modelling ofenterprises as service system entities• Novelty: value model ontology that ontologicallycommits to S-D LogicNFoS 2013 Lacco Ameno, Ischia - Napoli, Italy -- 20/06/2013Geert Poelspag. 12
