    • Trends in Information ModellingConfigurable Reference Models &ProcessBuilding Blocks
    • Idea: Streamlining Information Modeling

      Warehousing & 3rd-Party-Deal
      Idea: Generating modelvariants automatically

    • Introduction – Reuse of Information Models
      Reuse of information models implies complying with needs of different user groups
      company-specific user groups
      companies as user groups  “reference models”
      varying requirements
      to be considered within information models
    • Example: Requirements of Different Companies
      Business characteristics (e. g. type of trade business)
    • Example: Requirements of Company Specific User Groups
      Perspectives
      DimensionsofPerspectives
      Modeling Purpose
      OrganizationalRole
      Further Influences
    • Resulting Problems
      Problems: Redundancies
      Increased modeling and maintenance costs
      Danger of Inconsistencies within the model base
    • Solution: Configurative Information Modeling
      Constructionof an integrated total modelthatcontains all perspective-specificinformations
      Model elementsthatare relevant formorethanoneperspectivehavetobemodeledandmaintainedonlyonce
      Redundanciesand
      inconsistenciesareavoided.
    • Basic Concept: Model Projection
      Specific models for specific perspectives are provided via model projection
      Model elements that are not relevant for a specific perspective are hidden
      Models for specific perspectives are reprensented by viewson the integrated total model
    • Configuration Mechanisms
      Model Type Selection
      Selection of different model types for different perspectives
      (e. g. ERM vs. Technical Term Model)
      Element Type Selection
      Variation of model types for different perspectives
      (e. g. annotation of organizational units in the EPC)
      Element Selection
      Hiding of non relevant, single model elements
      Synonym Management
      Perspective-specific exchange of synonyms
      Representation Variation
      Variation of symbols
      Variation of model topologies
      Representation variation of configuration points
    • Model Layers

    • E. g. Organizational Design
      Configuration Mechanisms: Model Type Selection
      Model Types: resulttypesof a modelinglanguage:EPC, ERM etc.
      MetaMeta Model Layer:assignmentofperspectivesto model types
      Meta Model Layer: Language specificationsof non selected model typesdisappear
      Model Layer: Modeling with „forbidden“ languagesisnolongerpossible
    • Configuration Mechanisms: Element Type Selection
    • Configuration Mechanisms: Element Type Selection
      Meta Meta Model Layer:Reduction of model types by element types
    • Configuration Mechanisms: Element Type Selection
      Meta Model Layer:Element types disappear from the specifications of model types
    • ProcessBuilding Blocks
    • Problem of Governmental Processes
    • Firefighters

    • Traditional Process Modelling
      Traditional Modelling Approaches:
      Use of generally applicable modelling languages
      Not domain specific (harder to understand)
      High/varying level of detail (not always required)
      High degree of freedom (difficult to analyse)
      Syntactically complex (requires expert knowledge)
      Time consuming
    • Process Building Blocks
    • PICTURE Language Constructs (II)
    • Example for PICTURE Language Constructs
    • Objectives and Challenges
      Objectives of PICTURE
      Get an overview of the whole process landscape of a public body
      Efficient identification and analysis of possible reorganisation activities (organisational and technical)
      Challenges
      Many interdependent processes
      Huge amount of functional process know-how of employees
      Limited time of employees
      Handling and presentation of a huge amount of processes
      Maintenance and reutilisation of existing processes
    • Potential of the Building Block-Based Process Modelling
      Higher comparability of particular types of model elements to present activities
      Increased impact of individual elements on the meaning of the whole model
      If possible: immediate use of domain-specific terminology within the process building blocks to increase the comprehensibility (e.g. “Undertake formal check”)
      Highlighting function for relevant issues (e.g. “Transfer data in computer system”)
      Limiting function for non-relevant issues (e.g. no graphical representation of complex checks of content as it is enclosed in the building block “Check content”)
       Result: Better comparability between models
