Which one of the following business analysis planning and monitoring techniques can be used to define and document the business analysis approach?

Process modeling visually represents workflows and activities within a domain, allowing the BA to understand scope, stakeholder interactions, and the complexity of work - all of which directly inform the design of the business analysis approach. By modeling current and future state processes, the BA can determine which elicitation techniques, analysis methods, and deliverables are most appropriate for the engagement.

Structured walkthrough is a peer review technique used to validate and verify deliverables with stakeholders, not to define how the BA work will be approached.

Decision analysis is used to evaluate competing options and select among alternatives, not to document the methodology for conducting business analysis.

Control charts are a statistical quality monitoring tool used to track process variation over time and are not applicable to defining a BA approach.
