Human Research and Engineering Directorate
• Powerful tool for estimating system performance as a function of human performance
• Rendered useless if analyst can not interpret the data
FOCUS: Accentuate the strengths of IMPRINT by redesigning and developing analysis friendly reports

Version 6 ReportsVersion 6 Reports
• Good measures of overall system performance
• Limited look into operator workload
KEY ISSUES
- Plotting Workload Over Time - No report to show operator activity during
points of high workload(especially in VACP/Goal)
