Mturi licentiate presentation

  1. 1. Towards a Universal Business Process Model Repository for Process Model Reuse Mturi Elias Supervisor: Paul Johannesson Department of Computer and Systems Science (DSV), Stockholm University (SU), Sweden
  2. 2. Agenda 1. Background and Motivation 2. Research Problem and Questions 3. Research Objectives 4. Research Process 5. Research Contribution 6. Conclusion and Future Research Directions
  3. 3. Background and Motivation  Increased adoption of BPM – increased economic pressure  One of the most important aspects of BPM is business process modeling  Benefits of modeling business processes:  process improvement, understanding, communication, aligning Business and IT, model-driven execution of processes, performance measurement, process analysis and simulation, knowledge management, change management  Besides these benefits, modeling is a complex, time consuming and error prone task  Reuse of process models can reduce the cost, complexity and time
  4. 4. Background and Motivation  One of the proven approach for supporting reuse is a process models repository  The process model repository offers a space for  storing, maintaining and changing process knowledge for future reuse.
  5. 5. Research Problem and Questions  Existing process model repositories have not yet succeeded in being adopted to support process model reuse. Reasons includes 1. Most of existing repositories are proprietary—they are not publicly open 2. It is difficult to search and navigate across repositories because they follow different business and process classification schemes. 3. The process models are not goal related, making it difficult to get an understanding of what business goals that are realized by a certain process model 4. Existing repositories have limited scope—they lack completeness
  6. 6. Research Problem and Questions  How should a process model repository be designed in order to support reuse of process models? More specifically:  RQ1. What requirements should process model repository possess in order to increase the probability of process model reuse?  RQ2. What kind of information is required for describing process models that should be included in the repository structure to improve (1) searching process models (2) navigation of a process model repository, and (3) understandability of process models  RQ3. How can process models from different modeling notations be stored in a process model repository?
  7. 7. Research Objectives  The main objective of this thesis is, therefore, to design the architecture of a universal process model repository  Specific Objectives: 1. To elicit the requirements for a process model repository 2. To develop a model of business process metadata 3. To develop a common format (language independent) of process description
  8. 8. Research Process Research Process (adopted from (Vaishnavi and Kuechler 2007))
  9. 9. Research Contribution 1. Requirements for a process model repository (paper 1) 2. A Business Process Metadata Model (BPMM) (paper 2) 3. A generic data model of a common format of process description (paper 3)
  10. 10. The Requirements for the UPR  Elicited preliminary requirements (defined as propositions) -- an exploratory study  Then validated the propositions -- an empirical study 1. The repository should be able to store process models in at least one process modeling language 2. The repository should allow storing process models regardless of their domain 3. Process models in the repository should be represented in both graphical and textual form 5. Business process should be represented by several process models having different levels of detail
  11. 11. The Requirements for the UPR (2) 5. The repository should store both business and process models. 6. The repository should allow maintaining multiple variants of a process model. 7. Process model should be annotated with information that can facilitate searching, navigating and interpreting process models 8. Process models in the repository should be categorized based on different classification schemes to facilitate navigation
  12. 12. A Business Process Metadata Model (BPMM)  The BPMM has been developed based on a systematic approach, which consists of three phases, Phase 1: Identification of process related concepts – from business frameworks, existing process classification schemes, organizations theory, business process perspectives Phase 2: Validation of the concepts – Empirical Study Phase 3: The model construction – defining metadata element and their relationship

  15. 15.

  16. 16. A Common Format of a Process Description  Consists - partial data model & mapping specification Step 1: Defined “process description” - based on the definition of process model and a business process Step 2: Generated a generic metamodel - to provide concrete elements of a business processes Step 3: Matched the generic metamodel to the process description (in Step 1) to form a generic process description that is further used to develop the partial data model Step 4: Defined a mapping specification -- the elements of generic metamodel are matched to the elements of modeling languages

  18. 18. Conclusion  In this research we propose a UPR  The research objectives were to:  elicit requirements for UPR  Develop a model of business process metadata  A common format of process description  The URP is an important step towards reuse of process models in order to reduce the cost of modeling business processes from scratch.  This entails challenges, but is relevant for practice, and serves as an exciting area for research.
  19. 19. Future Research Directions 1. Defining a pattern-based method for goal annotation of business process models in a repository 2. Development of a Business Process Metadata Annotation Tool for a Process Model Repository 3. Empirical evaluation of the Business Process Metadata Model
