Business Modeling In Healthcare - BA World 2007


Published on

This presentation looks at the role of business modeling when developing software in the healthcare industry. The importance of understanding the customer needs and domain is something that should be applicable across different industries. In particular, this presentation is from the perspective of a former aerospace system engineer.

Business Modeling In Healthcare - BA World 2007

  1. 1. From Aerospace to Healthcare: Perspectives on Business Modeling Ken Wong, Ph.D. Senior Systems Analyst McKesson Medical Imaging Group (MIG)
  2. 2. From Aerospace to Healthcare … Aerospace refugee (ex-Hughes/Raytheon) Air Traffic Management – STARS, … Air Command and Control – ACCS “Systems Engineer” (SE) Healthcare immigrant (ALI/MIG) Radiology Information Systems (RIS) - HRM Picture Archiving and Communications Systems (PACS) - HRS “Systems Analyst” (SA)
  3. 3. Overview Meeting customer “operational needs” From SE perspective From BA perspective From Healthcare perspective Workflow Redesign What are we doing at MIG?
  4. 4. Systems Engineering
  5. 5. Systems Engineering Emerged in 50’s driven by US DoD Applied to large system acquisitions, e.g., missiles and missile-defense systems Mandated disciplined development MIL-STD-499A “A logical sequence of activities and decision that transforms an operational need into a description of system performance parameters and a preferred system configuration”
  6. 6. Systems Engineering Process From DOD SFE
  7. 7. Operational Concept How the system will serve its users Operational need definition System mission analysis and performance Operational sequences and environments User and maintainer roles
  8. 8. NATO Air Command and Control System (ACCS) From
  9. 9. Business Analysis
  10. 10. Business Analysis IIBA ( “The business analyst understands business problems and opportunities in the context of the requirements and recommends solutions that enable the organization to achieve its goals.”
  11. 11. Rational Unified Process
  12. 12. Business Modeling Provides business context Organizational structure, roles and processes Similarities with SE operational concept “Optional”???
  13. 13. Healthcare
  14. 14. Healthcare and IT IT is relatively new to Healthcare, e.g., Hospital Information Systems (HIS), Electronic Healthcare Records (EHR), Computerized Physician Order Entry (CPOE), … Key drivers Patient Safety – “To Err is Human …” Efficiency/Cost Buzzword: Workflow
  15. 15. Radiology Workflow From Siegel and Reiner
  16. 16. Introducing PACS
  17. 17. Radiology Workflow with PACS From Siegel and Reiner
  18. 18. Workflow Redesign
  19. 19. Workflow Interruptus Software will impact users and workflows E.g., FAA controller requirements Conservative Safety-critical From
  20. 20. Workflow Reality Check Operational <-> Functional disconnect Users out of the loop Workflow disrupted “Unintended consequences …” Patient safety issues Users are revolting E.g., NATO ACCS “HMI Optimization”
  21. 21. Workflow Redesign
  22. 22. MIG
  23. 23. ALI/MIG Then … “Four people in a room and 6 months later …” Workflow Redesign ... and now Over 200 in R&D and growing “Whither the business model?”
  24. 24. MIG Requirements Process Functional Analyst create business model Enterprise and Usability Analyses E.g., Business Use Cases, Personas, … Systems Analyst create system model Software Requirements and UI design E.g., System Use Cases, Interaction Design, … Process being test driven as we speak
  25. 25. Business Model Users: Personas Workflows: Business Use Cases New customer workflow with system Identifies user goals -> System Use Cases Validated with customer
  26. 26. E.g., Critical Test Result Reporting 1. The interpreting physician detects critical condition in study. 2. The interpreting physician sends critical test result to the referring physician, which is logged. 3. The referring physician is periodically reminded to retrieve the message. 4. The referring physician acknowledges receipt, which is logged. 5. Hospital administrator creates critical test reporting communications report.
  27. 27. Conclusions Operational <-> Functional disconnect Issue across domains and industries Software WILL impact workflow Workflow redesign Business modeling a necessity Business Use Cases help transition customer workflows
