What the business analyst does
Taking the system development site as an example, the biggest role of a business analyst is to understand the client's current business and convey the contents, including the management's intentions, to the development department. Clients do not necessarily have a deep knowledge of computer systems, and it is rare that they know what they need at the time of the request. There are often only rough requests such as "I just want to make the work environment more convenient than it is now." That's where business analysts come in. By communicating closely with the client, we can accurately read the system that the client wants to create.
The next task is to mediate communication with each department related to the project. In addition, we will organize what is necessary to develop and build an IT system and conduct research on cost performance. The project will move along the path created by the business analyst. Sometimes, a business analyst goes in the wrong direction, and the entire project strays, resulting in failure.
