Service-Oriented Modeling Strategy and Approach

  1. 1. Chief Principles of Service-Oriented Modeling www.ModelingConcepts.com
  2. 2. VISION, MISSION, AND STRATEGY
  3. 3. Fundamental Approach Vi What is? si The service-oriented modeling framework methodology offers “used to be”, “as is”, and “to be” business and technological transformation models for service and environment development on How? By employing service-oriented modeling principles
  4. 4. Modeling Mission Plan small, dream big; test small, execute big! M What is the mission? is si Proposing a solution to an organizational problem by on • Creating a miniature mockup of a final software product • Forming a small replica of a service and simulating a service ecosystem • Envisioning a virtual computing world • Verifying assumptions Why? • Promoting expenditure reduction and asset consolidation • Fostering asset reusability • Accelerating time-to-market • Increasing communication between stakeholders How? • Transforming service internal and/or external environments by employing models • Adhering to service modeling best practices • Using tools • Employing modeling environments
  5. 5. Modeling Driving Strategy St ra What is? t eg Service and environment transformation to offer a solution by employing four chief perspectives: in the y box, above the box, below the box, and out of the box How? In the Box: Internal Service Design Out-of-the-Box: Environment Design, such as Service distribution, interoperability, Integration, and deployment Above-the-Box: Best Practices, Governance, Business Imperatives, Business Requirements Below-the-Box: Separation of Concerns, Granularity Management, Loose Coupling
  6. 6. TERMINOLOGY
  7. 7. What is a Service? Se rv What is? ic Any piece of software, process, concept, and idea that has a life span and offers a solution to a problem e Service Attributes Contextual formation: Capability, Abstraction, Functionality Structural formation: Atomic Pattern, Composite Pattern, Cluster Patten If a piece of software, a process, a concept, or an idea has not been born, by definition it does not have a lifespan, and thus it is not a service
  8. 8. What is Service Modeling Life Cycle? Li fe Service Life Span Cy cl e What is? A life span of a service during which its continuous evolution commences at the inception stage and progresses through design, architecture, construction, and operations. When necessary, this venture retracts back to earlier development stages
  9. 9. What is Service and Environment Modeling? M Service Metamorphosis od el in g What is? Transforming a service and an environment during their life cycle to provide a solution How? By employing transformation models and adhering to best practices
  10. 10. What is a Transformation Model? M What is? od A unit of work that enables service and environment transformation el For example a model can be a design model, an analysis and discovery model, and more What are Model Components? The necessary tools, methodologies, disciplines, processes, best practices, time frame, languages, and score card that are employed to transform a service and/or its environment
  11. 11. Transformation Models Again, any model that transforms a service and/or its environment must offer best practices, methodology, disciplines, languages, tools, score card, timeframe, and a process
  12. 12. What is a Dynamic Transformation Model? What is? A model that accommodates the transformation of a service and/or an environment during multiple development life cycle stages by offering different best practices, tools, methodologies, and other model components Example The depicted discovery and analysis dynamic model accommodates service identification and inspection in different life cycle stages, for each of which distinct methodologies, best practices, and other model components are offered Service Discovery and Service Discovery and Service Discovery and Analysis Analysis Analysis During During During Design Time Construction Time Run Time
  13. 13. Forward and Backward Service Transformation What is? Forward Transformation Service and environment development that progress towards the production state of a life cycle Backward transformation Service and environment are reevaluated, reanalyzed, or redesigned How? By employing transformation models Forward Transformation Backward Transformation
  14. 14. MODELING PRACTICES
  15. 15. Modeling Framework Fr am What is? A modeling framework identifies modeling practices, modeling environments, modeling disciplines, modeling ew artifacts, and solution entities or k
  16. 16. Contextual Modeling Practice Co What is? nt Semantic transformation of a service or operating environment in a certain direction: ex generalization, specification, expansion, or contraction tu Semantic means service and environment al capabilities, functionality, specialties, abstraction levels, dependencies, relationships, and contracts How? Generalization: elevating abstraction level of capabilities Specification: reducing abstraction level of capabilities Expansion: expanding service offerings boundaries across a distributed computing environment Contraction: trimming down service offerings boundaries across a distributed computing environment
  17. 17. Structural Modeling Practice St What is? ru Transformation of a service or operating environment logical or physical formation in a certain ct direction: generalization, specification, expansion, or contraction ur Logical or physical formation means service and al environment distribution, integration, deployment, configuration, and granularity How? Generalization: increasing service logical and physical boundaries Specification: decreasing service logical and physical boundaries Expansion: expanding a distributed environment across an organization and beyond Contraction: contracting a distributed environment
  18. 18. Modeling Transparency Tran sp ar What is? en Business, technological, architectural, and operational aspects of service and environment modeling operations cy should be transparent to stakeholders How? Used-to-Be: depiction of service and environment past states As-Is: illustration of service and environment current states To-Be: description of service and environment target states
  19. 19. Modeling Granularity G ra n ul ar ity What is? Applying different service and environment transformation levels in four different perspectives: business, architectural, technological, abstraction How? Business granularity: using different levels of business processes – small or large scale of business activities Abstraction granularity: employing different levels of abstractions to offer a solution Technological granularity: applying different levels of technological solutions to a problem Architectural granularity: applying different levels of design and architecture remedy to offer a solution
  20. 20. Service Typing What is? Classification of services by origin, logical or physical structure, and context How? By employing a categorization method
  21. 21. Service Taxonomy Ta xo What is? nom Categorization of services based on their business, technical, architectural, and abstraction attributes y How? Leading categories: business and technical services Subcategories: classifying business and technical services into sub-types
  22. 22. Modeling Patterns and Anti-Patterns Pa t te What is? rn Repeatable template solutions that are road tested and offer modeling best practices s How? By employing five categories of modeling patterns: Modeling roadmap patterns: modeling strategy patterns Service discovery and analysis patterns: patterns that enable service identification and inspection Service categorization patterns: patterns that assist with service classification and taxonomy establishment Service contextual modeling patterns: patterns that guide semantic service and environment modeling Service structural modeling patterns: patterns that assist with logical and physical service and environment modeling
