Summary
Certification alone doesn't guarantee salary increase or job offers. Certification signals credibility + systematic knowledge.
Prioritize: (1) Actually learn BABOK (not just memorize for exam); (2) Choose cert matching your level and target market; (3) Combine cert with portfolio of real case studies with impact data.
One BA with 3 case studies showing business impact is more convincing than a CBAP with no real proof.
