Business analyst is a person who analyze, transform and ultimately solve the problem with their skills. Many BAs get their start as a subject matter expert (SME) on a big project in their organization. Another common approach is to be a developer-who can write and speak to the client. One other option is to find a BA training program. Many of these are aimed at existing BAs who are looking to improve their skills and resume, and are priced for professionals. MS certification won't help much. But if some SDLC experience in any capacity is there can help you. The ability to draw a process with some sort of recognized boxes and lines notation,like UML process diagrams, BPMN, or data flow diagrams. or else you can even learn online. Having a work experience will definitely help you but in the same sector.
