The IS Core: An Integration of the Core IS Courses

open access: yesSSRN Electronic Journal, 2009
This paper describes an innovative, integrated implementation of the core Information Systems courses. While the published IS curriculum provides standards on course content, it gives little direction on the implementation of the courses. At Brigham Young University, we have reengineered the traditional topics of analysis, database, design, development,
