Catalog Description:

Introduces the systems life cycle and basic techniques for stating and analyzing information systems requirements, and determining systems economics and computer controls. Illustrates the iterative nature of the information systems analysis and design process. Introduces systems design, flow charting, program structures and user interfaces. Hardware/software selection, evaluation, and alternative systems configurations, systems implementation, conversion and post implementation review are studied.
  Course Objectives: • Develop competence in using modeling tools and techniques for systems analysis

• Experience the process of developing information systems requirements

• Learn how to use a CASE tool to support structured analysis activities
