Presentation Transcript

  1. Incremental Commitment Spiral Model, Expedited Engineering, and Kanban Jo Ann Lane and Alexey TregubovUSC CSSE Rich Turner Stevens University

  2. Outline • Incremental Commitment Spiral Model (ICSM) Overview • ICSM and lean engineering • Kanban processes for large, complex development organizations CSSE ARR 2013

  3. What is the ICSM? • Risk-driven framework for determining and evolving best-fit system life-cycle process • Integrates the strengths of phased and risk-driven spiral process models • Synthesizes together principles critical to successful system development • Stakeholder value-based system definition and evolution • Incremental commitment and accountability • Concurrent hardware, human factors, and software system definition and development • Evidence-based and risk-based decision-making Principles trump diagrams… Principles used by 60-80% of CrossTalk Top-5 projects, 2002-2005 CSSE ARR 2013

  4. Risk-Driven Scalable Spiral Model: Increment View Unforeseeable Change (Adapt) Rapid Change Agile Rebaselining for Future Increments Future Increment Baselines Short Development Increments Deferrals Foreseeable Change (Plan) Short, Stabilized Development of Increment N Increment N Transition/ Operations and Maintenance Increment N Baseline Stable Development Increments Artifacts Concerns High Assurance Future V&V Resources Current V&V Resources Verification and Validation (V&V) of Increment N Continuous V&V CSSE ARR 2013

  10. Classes of Service • Critical Expedite • Important • Date Certain • Standard • Background CSSE ARR 2013

  11. Health Care Example • New capability to interface to a new health insurance company • New capability to integrate and analyze information from multiple patient telemetry systems to improve diagnostic capabilities • User response improvement • Periodic upgrade of pharmacy formulary information • Patient safety issue due to interoperability problem CSSE ARR 2013

  12. Kanban Flow for Healthcare Examples CSSE ARR 2013

  13. Future Work • Continue work on • “Value” strategies • Priority strategies • Identify organizations to pilot • Work with Kanban tool vendors More details on this in next presentation… CSSE ARR 2013
