Before moving to the next chapter, ensure you can:

Explain the difference between functions, processes, and servicesIdentify actors for a business functionDraw a use case diagram for a bounded scopeIdentify business rules from requirements or policiesBuild a scenario variation matrix for a functionExtract requirements from use cases and SVMs

Reflection Questions

Apply these concepts to your own context:

1. Think about a function in your organization. What actors interact with it? What rules govern its variations?

2. Are business rules in your organization documented explicitly? What problems arise from undocumented rules?

3. If you built an SVM for a key function, would stakeholders agree on the scenarios and outcomes? What disagreements might surface?
