3. Business Analysis Frameworks (27%)

Domain 4 is the second-largest slice of the exam — bigger than Agile, more than half the size of Domain 1 — and it's the one candidates most often skim, because "business analysis" sounds like a separate job title rather than exam content. That skim is exactly why this domain quietly costs candidates points: it isn't separate, and treating it like an afterthought fails you on questions that look like they belong to Domain 1 or Domain 3. The ECO explicitly tests how BA work integrates with project management, in both predictive and adaptive settings, across the full life cycle from gathering requirements to confirming a delivered product actually satisfies them — and, as the ⚠️ Exam Traps in this phase show, several of the confusions candidates carry in here are about role titles that sound interchangeable but aren't.
