Business analysis helps an organization to improve how it conducts its functions and activities in order to reduce overall costs, provide more efficient use of resources, and better support customers. It introduces the notion of process orientation, of concentrating on and rethinking end-to-end activities that create value for customers, while removing unnecessary, non-value added work. The person who carries out this task is called a business analyst or BA.

Those BAs who work solely on developing software systems may be called IT Business Analysts or Technical Business Analysts.
