Information Systems Analysis and Design

BA 453.01 Students learn to complete the phases of the systems development life cycle--feasibility, analysis, design, implementation, and maintenance--using structured tools and techniques, project management, and oral presentations. Topics include the roles of systems analysts, designers, and programmers; application of multiple development methodologies; systems requirements determination; data flow diagramming; input/output design; human factors; object-oriented analysis and design techniques; use of the project repository; and global and ethical concerns in systems development.
