  23. 23. Detailed Decision Requirements
  24. 24. Good Decision RequirementsInformation Know-how• What is needed? • How to make it• Where does it come • How to improve it from?Precision Automation• Exactly how? • All automated?• How to avoid • If not, how much can technical details? be and for whom?

  27. 27. Discovering Decisions From Process• A business process model can be an effective source for identifying high-level decisions• Prioritize decisions to know where to start
  28. 28. High-Level Decision & Dependencies
  29. 29. Simple Supporting Decision • Larger node is the subject of the diagram • Context established by drilling down from high- level decision • Only the dependencies of the subject decision are shown • All of the business logic is defined in the supporting decisions
  30. 30. A More Involved Example • Multiple layers of decision dependencies • Abstraction of full story • 3 different patterns of how to handle different states • 1 state breaks all patterns and has separate diagram
  31. 31. Full Diagram Depicting All States
  32. 32. A Tricky Decision Decomposition• A seemingly simple decision was complicated by lots of exceptions to the basic business rules• Discovering the proper decomposition was key to defining a satisfactory solution
  33. 33. Initial Attempts • Business rule requirements initially gathered as an unorganized list • A manageable number of business rules, but with lots of seemingly complicated exceptions • 3 initial attempts to synthesize a decision structure from the bottom up failed to support the business rule requirements
  34. 34. Successful Decision Decomposition • Partial solution by eliminating exceptions • Switched analysis from negative rules to positive rules • Complete solution found after refocusing on a top down approach
  35. 35. Rule Family Template• Business rules are defined in rule families• Multiple conditions, one conclusion• A message explaining each negative rule
  36. 36. Sample Business Rules• Simplified version with exceptions removed• Key elements are – Negative rules contain business rule statements – Positive rules complete full coverage
