So, who is this BA and what is their importance in a project? The simple definition of a BA is someone who analyzes an organization or business domain (real or hypothetical) and documents its business or processes or systems, along with assessing the business model or its integration with technology. Business Analyst helps in guiding businesses in improving processes, products, services and software through data analysis.
