The software engineering discipline is plagued with software defects, budget and schedule overruns, and failed software development projects. Although progress has been made in recent years, software defects are still common and are costing the US economy billions of dollars each year. In this presentation, Dr. Wilkerson will review some high-profile software project failures and will provide an overview of two methods of software defect reduction: software inspection and test-driven development. He will present the results of a quasi-experiment comparing the defect reduction effectiveness and relative costs of these two methods and will discuss the implications of this research and future research that needs to be conducted in this area to continue progress on reducing software defects in software development projects.


Jerod W. Wilkerson earned B.S. and M.S. degrees in Accounting from Brigham Young University and a Ph.D. in Management Information Systems from the University of Arizona. Prior to earning his Ph.D. and joining the faculty at Penn State, Erie, he spent ten years in industry working as a software developer, a project and business manager, a consultant, and a business owner. He founded and served as President of The Object Center-a consulting and training company focused on object technology and web development. His consulting and training clients have included the U.S. Department of Defense, several state and local government agencies in Utah and Texas, and over 20 business organizations-including Lockheed Martin, Raytheon Missile Systems, GMAC, J.P.
