  1. Using reference models to drive business transformation in the HE sector Dr Samia Oussena Thames Valley University

  2. Enterprise information system design • Evolution from a centralised mainframe applications to a services oriented architecture • Understanding the business process and aligning the development or the procurement of services to support the business process

  3. Business modelling as a transformation tool • Business process involve workflow management • Formalising is a shared way of understanding the way the things work • Process model help support of the quality management system

  4. COVARM project • The COVARM project sets out to contribute a reference model for a “Course Validation” service to become a component of the JISC eFramework Programme.

  5. Thames Valley University (Lead partner) Prof. Balbir Barn Dr Samia Oussena Dan Sparks University of Manchester Dr Hilary Dexter Dr Jim Petch Manchester Metropolitan University Dr Mark Stubbs Staffordshire University Prof. Mark Stiles Dr Jennifer Ealing and Hammersmith West London College Satwant Deol Project Consortium

  6. Course validation process as a value creation process

  7. Reference Model • A reference model is based on a small number of unifying concepts • An abstraction of the key concepts, their relationships, and their interfaces both to each other and to the external environment. • A reference model may be used as a basis for education and for explaining standards to a non-specialist • can be viewed as a framework for comparing architectures and operations of existing and future systems.

  8. Reference model • A framework can be used for specifying requirements and benchmarks in procurements or development of systems • The codification of interface structure will also encourage the development of software tools to enable the development of software tools that conform to the reference model

  9. COVARM approach • Fundamentals • Model based approach using UML (1.5 and 2.0) • Application and adaptation of software engineering methods – component based development and Rational Unified Process • Iterative • Stages

  10. Method principles Business process based UML end to end Model driven functional Adapted web services development method Information Model data Component based Principles • Grounded Case Study Approach • 4 case studies • review by an independent HEI • compare against survey results

  11. Stages

  12. Business process characteristics modelled • Stages • Roles • Objects and their flow – instances of docs produced • Events – something that triggers a set of activities • Collaborations – activities executed by two or more roles • Activities • Constraints • Specific activities to support eLearning • Life-cycle / states of objects – Programme • Interfaces with other enterprise information systems • Reference Docs – e.g. strategy docs

  13. Process model example

  14. Domain information model • UML class diagram for capturing set of elements and roles in the course validation domain • High level of abstraction with only key relationships between the elements included

  15. Domain model example

  16. Synthesizing the process models

  17. Rule based approach to process and information synthesis • Identify elements in a process that were common to all four institutions • Identify the principal variation points where an institution may differ from others • Define activities that are unique to an institution and provide a mechanism for those activities to be integrated into the common set.

  18. Synthesis Rules

  19. Process model: synthesis

  20. Information model: synthesis

  21. Stages

  22. Design the web services • Model the web services at the business level • Define XML data representations of the information consumed and produced by services • Generate appropriate implementation models of the service specifications.

  23. Modelling services specification • Method based on a number of sources. (Cheesman Daniels, D’Souza and Will..)

  24. Initial results • Positive response from institutions whose enterprises have been modelled. • Staffs have indicated that this activity has raised some questions on their processes • Manchester want posters of the process! • TVU have expressed interest in the additional reporting that will be possible via tools hosted on the reference model • Process Patterns emerging from the models • Consultation with expert; • Assessment and Approval; • Convene Panel; • Meet Conditions; • Refinement Pattern • Sign-off Pattern; • Collaboration Pattern;

  25. Initial results (cont) • Business Process and Information models from 4 institutions • Rules for combining process models • Generalised Canonical Process and Information Model • Utility web service : document management service • Business web service: Event coordination service
