Premium Publishers

Situation: Premium Publishers is a small publishing firm that specializes in reprinting classic literature. A year ago the IT staff developed a Web-based order entry system. The system has performed well, but the company would like to add more features and improve performance. So far, most of the maintenance has involved correcting minor errors.

1. What types of maintenance have the IT staff performed? What types of maintenance will they perform if the existing system is retained?

2. If new features are added, what methodology should the IT staff use to add new functions and enhancements?

3. What IT security measures should the firm adopt? Prepare a security checklist, and be sure to consider all six security levels.

4. Even though the new system is only a year old, e-commerce changes constantly. At what point should Premium Publishers consider replacing the Web-based system with a new system, and why?
