*Business Analyst Study Guide · Business Process Mapping · Last updated October 15, 2026 · https://www.certifyforce.com/study-guide/business-analyst/business-process-mapping/scoping-and-decomposing-complex-business-processes*

How to bound a complex process by its input and outcome, set its context with a capability model or SIPOC, and break it into readable levels of 8-10 verb-first activity boxes that drill down without losing scope.

- Certification: Salesforce Business Analyst
- Exam section: Business Process Mapping
- Study guide: https://www.certifyforce.com/study-guide/business-analyst

**Official exam objective:**

> Demonstrate how to define the scope of a complex business process and break it down into manageable steps.

## What the exam expects

- Define a complex process by its triggering input and final outcome (Lead to Revenue), not by the applications it touches.
- Set the context and boundaries with a capability model or a SIPOC before detailed mapping.
- Break the process into levels of about 8-10 activity boxes, each drill-down scoped by its parent box's inputs and outputs.
- Write steps as verb phrases with clear inputs and outputs, and settle audience, purpose and resources (RACI) before a workshop.
- Know who decides in a mapping workshop and which process to map first.

Key terms:
- **Input and outcome:** what starts a process and what ends it; together, its scope.
- **Activity box:** one step, labelled with a verb phrase and its resource.
- **Drill down:** opening a lower-level diagram that details one activity box.
- **Capability model:** a list of high-level process areas.
- **SIPOC:** suppliers, inputs, process, outputs, customers.
- **Process owner:** the person who owns the end-to-end process.

## Check yourself

- Why should a process be defined by its input and outcome rather than the application it runs in?
- When you drill down from an activity box, what limits the scope of the new diagram?
- Which two artifacts help define scope and context before a detailed map?
- When an organization is new to process mapping, which process should it map first?
- Who resolves a disagreement about the right sequence of steps during a mapping workshop?
