Why Study Systems Analysis and Design?

        Because we are in a modern generation, it is hard to imagine any industry or business that has not been affected by computer-based information systems and computer applications. Moreover, “analyzing” business requirements for information systems and “designing” information systems that fulfill business requirements and use information technology is needed. But first, what is an Information System or IS? An Information system is an arrangement of people, data, processes, information presentation, and information technology that interact to support and improve day-to-day operations in a business as well as support the problem-solving and decision-making needs of management and users. Second, what is information Technology? Information Technology is a contemporary term that describes the combination of computer technology (hardware and software) with telecommunications technology (data, image, and voice networks). In a business, all workers need to participate in the development of information systems—not just the information technology specialists to be able to compete to other organizations or gain a competitive advantage.

And now, If you want to build an information system, who are the stakeholders you want to build? But, what is a stakeholder? A stakeholder is any person who has an interest in an existing or new information system and stakeholders for information systems can be classified into 6 groups: (1) System owners, pay for the system to be built and maintained. (2) System users, actually use the system to perform or support the work to be completed. (3) System designers, design the system to meet the user’s requirements. (4) System builders, construct, test, and deliver the system into operation. (5) Systems analysts, facilitate the development of information systems and computer applications. (6) IT vendors and consultants, sell hardware, software, and services to business.

        Regardless of your academic field of study or chosen career, you will almost certainly participate in one or more of the above roles during an information system development project. Consequently, systems analysis and design is not a subject just for computer professionals only anymore.
