Embedded Decision Analysis: Systems Design Patterns

  1. 1. Systems Design Patterns for Embedded DA Somik Raha
  2. 2. Ground Principle Humans not replaced, but augmented
  3. 3. Purpose of Tool Consultative DA Embedded DA “Knobs for Nerds” Create custom models to meet particular issues in the situation ! “Lean Models” Train against common simple templates and deploy Bad idea to reuse models Good idea to reuse models
  4. 4. User Interface Consultative DA Embedded DA “Control-focused” Manage/Edit/Analyze ! “Role-focused” Multiple roles/views: •Decision-Makers •SMEs •Analysts ! Vignette from Finance Director
  5. 5. User Interface Consultative DA Embedded DA “Control-focused” Manage/Edit/Analyze ! “Role-focused” Multiple roles/views: •Decision-Makers •SMEs •Analysts ! Vignette from Finance Director
  6. 6. Workflow Consultative DA Embedded DA Facilitated through an expert analyst Real-time mediated by system Send out requests for data, carefully review the data received and plug into model for analysis. Distributed work across roles and geographies. System turns into a storehouse of useful information.
  7. 7. Workflow Consultative DA Embedded DA Facilitated through an expert analyst Real-time mediated by system Quote: The executive team was able to trust our process because we could show them our numbers in real-time, and the assumptions behind them. Send out requests for data, carefully review the data received and plug into model for analysis. Distributed work across roles and geographies. System turns into a storehouse of useful information.
  8. 8. Integrity of Model Consultative DA Embedded DA Pedigree assured by analyst Pedigree assured by system Power tools need careful control Tracks who changed what and why
  9. 9. Integrity of Model Consultative DA Embedded DA Pedigree assured by analyst Pedigree assured by system Power tools need careful control Tracks who changed what and why
  10. 10. Integrity of Model Consultative DA Embedded DA
  11. 11. Composite Context Consultative DA Embedded DA Decisions are one-off or unique. Decisions are made in the context of a stream of similar decisions. ! e.g. Other similar project decisions, or a portfolio of related decisions
  12. 12. Composite Context Embedded DA
  13. 13. Composite Context Embedded DA
  14. 14. Composite Context Embedded DA
  15. 15. In Summary Consultative DA Embedded DA Knobs for Nerds ! Facilitated through an expert analyst ! Pedigree assured by analyst ! Decisions are one-off or unique Lean Models ! Real-time mediated by system ! Pedigree assured by system ! Decisions are made in the context of a stream of similar decisions !
