41. A group of Risk Rules configured by Risk Analyst
Domain-specific language (DSL) is a programming language specifically
designed to working within a particular area of interest.
We could use Natural Language and use
a Framework like Cucumber
Scenario: Age Validation
Given an individual
When age bigger than 18
Then Approve
But, we decide to use a Mathematical
approach using Spring SpEL
"name": "Age Validation",
"description": "Check the age of an individual",
"resultSentence": "#anyClauseRejected ?
"REJECTED" : "APPROVED"",
"clauses": [{
"preCondition": "#person.age != null
"sentence": "#person.age >= 18"
}]

48. We want our squads to be as autonomous as possible.
If we don't have the document version, the coupling between Risk and Person
Microservices will be so high that it will be impossible to the squad to be
autonomous and to deliver fast.
/Control vs Velocity

49. We want to be able to deploy 1 new
product per week!
