- 35. 9% Decision Follows Rule
- 36. Business Rules in Action
- 37. Advanced Business Rules Computers are machines following rules. This means business rules are programs.
- 38. • Business rules are like programs – written by non-programmers • Business rules can be contradictory, incomplete, and complex beyond comprehension • Business rules have no built-in feedback mechanism:“It is the rule, because it is the rule” Business rules are Programs, just not very good ones.

Kennedy were both presidents of the United States, elected 100 years apart. • Both were shot and killed by assassins who were known by three names with 15 letters, John Wilkes Booth and Lee Harvey Oswald, and neither killer would make it to trial. • Lincoln had a secretary named Kennedy, and Kennedy had a secretary named Lincoln. • They were both killed on a Friday while sitting next to their wives, Lincoln in the Ford Theater, Kennedy in a Lincoln made by Ford.

- 57. 1 Categorizing Analytics Descriptive • Focused on gathering and collecting data • Key challenges: data volume and data variety • Key outcome: hindsight • Examples: reports, dashboards • Answers “What happened?” Predictive • Focused on understanding and explaining data • Key challenges: data velocity and complexity • Key outcome: insight • Examples: prediction models • Answers: “Why did it happen and what will happen next?” Prescriptive • Focused on anticipating and recommending action • Key challenges: execution • Key outcome: foresight • Examples: decision support, predictive apps • Answers: “What should we do?” 2 3
- 58. A Categorizing Analytics Explicit • Analytics are a key visible feature of the program • Programs are used by trained analysts and data scientists • Regular interaction during business hours Integrated • Analytics are included in another program • Analytics are consumed in- context by business users • Frequent, but irregular consumption during business hours Embedded • Analytics are invisibly part of a complex process • Decisions are made and executed in the process • Constant and ongoing optimization 24/7 B C
