The computer professional who studies an existing system with the goal of developing a computer-based system from it is called a system analyst. A system analyst's job is to examine an existing system and determine how it works, what its limitations are, and what can be done to improve it. They use this information to design a new computer-based system that meets the organization's needs, and work with programmers and engineers to develop and implement it. In simpler terms, a system analyst is like an architect who examines a building to see how it can be renovated or expanded to better suit the needs of its occupants. Instead of working with physical structures, a system analyst works with computer systems.
