Information system design

The drawing, planning, sketching, or arranging of many separate elements into a viable, unified whole. Whereas systems analysis is concerned with determining what the system is doing and what it should be doing, systems design is concerned with how the system is developed to meet the requirements of users. In the design process, the analyst develops alternative solutions and eventually ascertains the best design solution. In order to design a system the analyst must possess knowledge related to the following subjects: organizational resources; user information requirements; other systems requirements; methods of data processing; data operations; and design tools.
