Who produces and who consumes in MuleSoft's API-led delivery model: central IT unlocks systems with System APIs, LoB and central IT compose Process APIs, app developers self-serve to build Experience APIs and apps, with reusable assets created inside projects and consumer feedback steering what is produced next.

- Certification: Salesforce MuleSoft Integration Foundations
- Exam section: Identify the roles, responsibilities, and lifecycle of a integration project
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-integration-foundations

**Official exam objective:**

> Describe the characteristics and roles of an API-led IT delivery model that emphasizes both production and consumption.

## What the exam expects

- Assign each API-led layer to the group that typically builds it: central IT, LoB IT with central IT, or app developers.
- Describe what each layer does (System, Process, Experience) and where new consumer-specific logic belongs.
- Explain that reusable assets come out of normal project delivery and must be discoverable for self-service.
- Describe how consumer feedback and usage metrics keep the production and consumption cycle improving.

Key terms:
- **System API**: connects directly to a core system and unlocks its data while shielding the system of record.
- **Process API**: orchestrates data from System APIs and other Process APIs into reusable business logic.
- **Experience API**: adapts Process API output for one kind of consumer, such as a mobile app.
- **Self-service**: developers discover and consume published APIs without waiting on central IT.
