In today's complex projects, there is no more critical function than the function performed by business analysts. Business analysts serve as the link between the business interests served by the project and the technology that will be employed to deliver the functionality required by it. They are responsible for translating business needs into language that systems analysts can turn into a solution, for framing the problem and identifying the most appropriate solution. They keep the project focused on the needs for which it was initiated. They are often charged with gathering, documenting and tracking requirements, especially in software development and implementation projects.
