There is no single best business analysis certification, only the best one for the number of analysis hours you have already logged. Below roughly 3,750 hours the choice is the ECBA; from there the IIBA CCBA fits; past 7,500 hours the real decision is between the IIBA CBAP and the PMI-PBA. This guide ranks five credentials by that ladder.

Which of the five fits the analysis hours you have already logged?
Most comparison lists rank certifications by popularity. A more useful ordering is the one the credentials were designed around, which is how much documented work you can show. IIBA, the body behind four of the five credentials in this guide, builds its ladder on hours. PMI, which runs the fifth, builds its own on a separate guide and its own experience rules. Start with where you stand and the field narrows quickly.
