Current ProblemCurrent Problem
•Believe it or not, there are some students at SIU-E that do not write their own code for programming assignments.
•Instructors need a way to check multiple sections of programming assignments for similarity.
•Doing this by hand takes way too long.
•There exists an application hosted by U.C. at Berkeley called MOSS to compare programs, but the process of submitting them is currently very inconvenient.

MOSS
Based on the client’s requirements for accessibility, group skills, and the availability of development tools, we chose a Windows NT platform running Internet Information Server.

MOSS
Based on the client’s requirements for accessibility, group skills, and the availability of development tools, we chose a Windows NT platform running Internet Information Server.
Based on this platform choice we needed to see what we could or could not do in terms of talking to MOSS.

The Risk Mitigation Effort has:
•Allowed us to make certain that we will be able to send/receive information to/from MOSS based on our platform choice
