strukt - A Pattern System for Integrating Individual and Organizational Knowledge Work

  1. 1. strukt - A Pattern System for Integrating Individual and Organizational Knowledge Work Ansgar Scherp Daniel Eißing Steffen Staab scherp@uni-koblenz.de ISWC, Bonn, Germany October 26, 2011
  2. 2. Ansgar Scherp – Integrating individual and organizational knowledge work 2 von 17 Scenario: Architectural Office
  3. 3. Ansgar Scherp – Integrating individual and organizational knowledge work 3 von 17 Goal and Approach  Goal  Software system for planning weakly structured workflows and  integrating them with structured workflows  Solution approach  Integration by means of a core ontology
  4. 4. Ansgar Scherp – Integrating individual and organizational knowledge work 4 von 17 Organizational Knowledge Work  Knowledge from the point of view of the organization  Business process modeling [Stahlknecht & Hasenkamp’04]  Goal: make implicit procedural knowledge explicit  Optimizing processes by means of analysis and planning  Business process [Hammer & Champy ‘03], [Abts & Mülder’11]  Targeted chain of organizational activities  Defined start/end, measurable input/output  Added value to the customers  Structured workflows
  5. 5. Ansgar Scherp – Integrating individual and organizational knowledge work 5 von 17 Individual Knowledge Work  Knowledge from the point of view of the worker  Characteristics [Schwarz et al. 2001]  Dynamic (ad-hoc), complexity, self-organization, interdisciplinary and communication-oriented, intervals between repetitions  Not ammenable to explicit planning  Repeating elements that are worth to capture  Weakly structured workflows
  6. 6. Ansgar Scherp – Integrating individual and organizational knowledge work 6 von 17 Workflow Models and Instances Workflow model defines  Activities, alternatives, and participating roles  Workflow instantiation is the execution under  Consideration of current workflow parameters [Schwarz et al. 2001]
  7. 7. Ansgar Scherp – Integrating individual and organizational knowledge work 7 von 17 Requirements a) Weakly structured workflows (WsW) b) Structured Workflows (SW) c) Integration of WsW and SW d) Models & Instances e) Tools & Planning of WsW (1) Weakly Structured Workflow Pattern (2) Structured Workflow & (3) Transition Pattern (4) Workflow Integration Pattern (5) Workflow Model Pattern (6) Condition Pattern (7) Resource Pattern (8) Status Pattern (9) Scheduling Pattern
  8. 8. Ansgar Scherp – Integrating individual and organizational knowledge work 8 von 17 Challenges  Adaptation of workflow instances at runtime  Without the need to adapt the workflow model  Abstract workflow instances to workflow models  Put workflow instances into context  Reification  Descriptions & Situations (DnS) pattern provided by DOLCE  Defines context by means of concepts (roles)
  9. 9. Ansgar Scherp – Integrating individual and organizational knowledge work 9 von 17 DnS Example: Building Application Description defines roles  StructuralEngineer  ComputeStatics  CreateGroundplan  …  Situation defines objects tmueller-1 : NaturalPerson a-compute-statics-1 : Action a-create-groundplan-1 : Action …  DnS pattern  Clear separation of workflow models and workflow instances  Applicable to structured workflows and weakly structured workflows  Ontology design patterns of base on DnS Source: info-bauntrag.de classifies
  10. 10. Ansgar Scherp – Integrating individual and organizational knowledge work 10 von 17  Execution of „Planning a building construction“ Example: Structured Workflow  Structured Workflow Pattern + Transition Pattern Prepare Application File Application …
  11. 11. Ansgar Scherp – Integrating individual and organizational knowledge work 11 von 17 Social roles of the entities Entities of the real world Example: Structured Workflow  Execution of „Planning a building construction“  Structured Workflow Pattern + Transition Pattern
  12. 12. Ansgar Scherp – Integrating individual and organizational knowledge work 12 von 17 Example: Structured Workflow  Integration with weakly structured workflow  Workflow Integration Pattern
  13. 13. Ansgar Scherp – Integrating individual and organizational knowledge work 13 von 17 Example: Weakly Structured Workflow  Activities for preparing a building application using the Weakly Structured Workflow Pattern
  14. 14. Ansgar Scherp – Integrating individual and organizational knowledge work 14 von 17 Axiomatization in Description Logics  Consistency checking at design time
  15. 15. Ansgar Scherp – Integrating individual and organizational knowledge work 15 von 17 Related Work of Further: KBPI [Dalmaris et al. 2007], KMDL [Gronau et al. 2008], sEPK + sBPMN [Hepp et al. 2006], and KMO [Holsapple u. Joshi 2004]
  16. 16. Ansgar Scherp – Integrating individual and organizational knowledge work 16 von 17 Prototype
  17. 17. Ansgar Scherp – Integrating individual and organizational knowledge work 17 von 17 Summary / Discussions  Young Talent Award of the Knowledge Management Group Karlsruhe, Germany Thank you for your attention!  Why not a more light-weight solution?  Looking for a good solution, not minimalistic one  Probably possible to do it more light-weight  Is this really a pattern-based ontology?  Pattern: generic solution to recurring problem  Pattern system: set of patterns related to each other and designed to be applied together
