  1. Organization Technology Process Business Process Reengineering: Principles, Methods, Tools and Implementation Minder Chen, Ph.D. MS-5F4 School of Management George Mason University Fairfax, VA 22030 Phone: 703-993-1788 Internet: MCHEN@GMU.EDU

  2. Processes Are Often Cross Functional Areas "Manage the white space on the organization chart!" Customer/ Markets Needs Supplier Value-added Products/ Services to Customers "We cannot improve or measure the performance of a hierarchical structure. But, we can increase output quality and customer satisfaction, as well as reduce the cost and cycle time of a process to improve it."

  3. Definition of Reengineering The fundamental rethinking and radical redesign of core business processes to achieve dramatic improvements in critical performance measures such as quality, cost, and cycle time. Source: Adapted from Hammer and Champy, Reengineering the Corporation, 1993

  4. What Business Reengineering Is Not? • Automating: Paving the cow paths. (Automate poor processes.) • Downsizing: Doing less with less. Cut costs or reduce payrolls. (Creating new products and services, as well as positive thinking are critical to the success of BPR.)

  5. Reengineering Is ... • Obliterate what you have now and start from scratch. • Transform every aspect of your organization. Extremist's View Source: Michael Hammer, “Reengineering Work: Don’t Automate, Obliterate,” Harvard Business Review, July-August, 1990, pp. 104-112.

  8. BPR Principles • Organize around outcomes, not tasks. • Have those who use the output of the process perform the process. • Subsume information-processing work into the real work that produces the information. • Treat geographically dispersed resources as though they were centralized. • Link parallel activities instead of integrating their results. • Put decision points where the work is performed and build controls into the process. • Capture information once and at the source.

  9. Business Process Reengineering Life Cycle Define corporate visions and business goals Visioning BPR-LC Identify business processes to be reengineered Identifying Analyze and measure an existing process Analyzing Identify enabling IT & generate alternative process redesigns Redesigning Evaluate and select a process redesign Evaluating Implement the reengineered process Implementing Continuous improvement of the process Improving Manage change and stakeholder interests

  10. Phase 1: Visioning • Apply to enterprise-wide reengineering effort. • Develop overview of current and future business strategies, organizational structure, and business processes. • Develop organizational commitment to reengineering. • Develop and communicate a business case for action. • Create a new corporate vision. • Set stretched goals. • Prioritize objectives. • Assess implementation capabilities and barriers. Define corporate vision and business goals

  11. Phase 2: Identifying • Construct high-level process map • Develop a process hierarchy • Build enterprise-wide data models (optional) • Evaluate the processes • Select processes to be reengineered • Prioritize and schedule processes to be reengineered Identify business processes to be reengineered

  13. Criteria for Selecting Processes • Broken • Bottleneck • Cross-functional or cross-organizational units • Core processes that have high impacts • Front-line and customer serving - the moment of the truth • Value-adding • New processes and services • Feasible

  14. Phase 3: Analyzing • Conduct preliminary scoping. • Develop a high-level AS-IS baseline process model (work flow model). Avoid analysis paralysis by conducting preliminary analysis at fairly high level. • Surface purpose and assumptions of the process (Ask WHY?). • Perform activity-based costing: costs can be assigned based on actual activities and productivity. • Reveal hidden time and nonvalue-added activities. • Measure cycle-time and quality. • Measure profitability in terms of task, product, and customer type. Analyze and Measure an Existing Process

  15. Phase 4: Redesigning Identify enabling IT & generate alternative process redesigns Business Vision & Strategy Business-pulled How can IT support business strategies and business processes? How can business strategies be changed business processes be transformed using IT? Business Reengineering Technology-driven Information Technology

  16. Three Steps in Redesigning Processes • Simplification: • Task: Change business rules or procedures of a specific task • Workflow: A process chain is simplified by elimination of nonvalue-adding activities • Integration: • Redesign tasks into a logical and effective process. • A reengineered process often crosses functional boundaries. • It offers opportunity for eradicating interdepartmental redundancies and restructuring the organization. • Automation: • Usually accompanies nontechnical redesign of organization structures and procedures. • All reengineering costs and benefits can be projected into a model. • Reengineering often pays for itself - sources of funding for technology investments are frequently cost savings generated by organizational change.

  17. Phase 5: Evaluating • Develop criteria of evaluating alternatives of redesigned processes: Cost, Benefit, and Risk. • Evaluate design alternatives • Select and recommend a reengineered process Evaluate and select a process redesign

  18. Phase 6: Implementing • Plan IT implementation • Plan organization implementation • Conduct a pilot project • Develop a prototype system • Technical Design • Social Design • Evaluate results from the pilot project and the prototype • Prepare large-scale roll out Implement the reengineered process

  19. Phase 7: Improving • Develop performance measurement and reward systems in the reengineered process • Monitor process performance constantly • Improve the process on a continuous basis Improve the process continuously

The Quest of Competitiveness Downsizing Headcount & Restructuring the Portfolio Smaller Total Quality Management & Continuous Process Improvement Better (Kaizen) Enterprise-Wide Reengineering & Business Process Reengineering Much Better Reinventing Industries & Regenerating Strategies Different Adapted from: Gary Hammel and C. K. Prahalad, Competing for the Future, Harvard Business School Press, 1994.

  25. ICOM in IDEF0 The ICOM of a function represents certain system principles: Inputs are transformed into outputs, controls constrain or dictate under what conditions transformations occur, and mechanisms describe how the function is accomplished. An IDEF box and its ICOM can be described as: C "Inputs are transformed by the function into outputs according to controls, using mechanisms." O I M
