  3. Agenda • Motivation • Service Networks: • Introduction • Example • Service Network Notation • Analysis of Service Networks • Enhanced BPM Layering – SN4BPM • Enhanced BPM Lifecycle • Conclusions, Outlook

  4. Motivation • Service Networks: large, distributed cross-organizational service infrastructures • Bridge the gap between • Business strategy and business models • Service systems implementations • Comprehensive methodology for developing, monitoring measuring and optimizing Service Networks

  5. Service Network Notation: Introduction • Goal: represent interactions among participants (business entities) and their services in an abstract manner • Interactions are: • Offerings • Revenues • No implicit temporal flows (e.g. no workflows) • Target user: Business analysts • SNN models can be analyzed for: • Measurement/estimation of added value for each single participant as well as for the whole network • Optimization of value flows

  6. Service Network Notation: Example

  7. Service Network Notation: Analysis (1) Measure the performance of the network through Key Performance Indicators (KPIs) Connect KPIs to parameters given in SLAs and parameters given by the interacting participants Solve the following maximization problem

  8. Service Network Notation: Analysis (2) • In the telecommunications example: • Focus on the value created for the service provider (SP)

  9. Service Network Notation – Meta-model

  10. Enhanced BPM Layering Stack Service Network Process Models (BPMN) Orchestration Choreography technology-independent Composition BPEL4Chor BPEL Abstract BPEL Executable BPEL technology-specific Services

  11. The Enhanced BPM Lifecycle Process Models Analysis Modeling TopDown Rationalization BottomUp Monitoring IT Refinement SNN Models Execution Deployment

  12. Enhanced BPM lifecycle : Rationalization (1) The rationalization phase produces information which is used in the modeling or analysis phase Three ways of sequencing analysis, rationalization and modeling in the enhanced BPM lifecycle: Analysis–Rationalization–Analysis

  13. Enhanced BPM lifecycle: Rationalization (2) 3 Modeling–Rationalization–Analysis Sequence (BottomUp)

  14. Enhanced BPM lifecycle: Rationalization (3) Analysis–Rationalization–Modeling Sequence (TopDown)

  15. Conclusions and Outlook We propose • architecture to coordinate business processes lifecycle • abstract way to support business processes (in the SN level) and conversely a detailed description of the service network (in the BPM level) Thus Bridge the gap between SOA (IT) infrastructure and business decisions and strategies Future work: • Formulate variations of optimization problems involving KPIs and SLAs • Address the behavior of competing networks • ...
