ComputerAdvice System
2 Java server applications & 1 client applet JESS – runs knowledge script CA web-server – interface application
Connects to JESS via socketWaits for web client connection
CA client – connects to web-server. Handles user input and output

Verification
Verification - Required CA application stable Follows procedure exactly Completes all steps
Verification – Optional CA web-server stable CA web-server doesn’t hang

Validation
Evaluation Output must be reasonable Expert will validate
System incomplete More rules to add More expert consultation No validation present

Lessons Learned
Java JRE hasn’t behaved like it is platform independent.
Using 4 computers with 4 OS’s has been really helpful
JESS was a great expert system shell

Summary
System design and process complete Need to add more rules Need to update hardware database
Web application seems to work It’s been up for 3-4 days Web application will be very accessible
