Are Business Rules ?For Decision CAMP 2014

Kenny Shi, UBER

My Journey

DATA RULES MODELS

Business Rules Journey

Business asked“I want the changes done… yesterday!”“I said I wanted X, but you gave me Y!”“How do I know my rules are working as expected?”“What is UsrAddr.load()[0]?”

Engineering asked“Submit a request and we’ll prioritize.”“How often do you change rules?”“You can find all your rules on GitHub, just follow the code path.”“What do you mean by X?”

• Agility‐ Independent lifecycle of rules from code

• Separation of Concerns‐ Business owns Business Rules

• Manageability‐ Centralized repository, transparency, access

control

• Monitorability‐ KPI, performance, etc.
