ABSTRACT
The ability to destroy fleeing targets in a time critical environment is a key capability for the
successful completion of the Joint Forces Commander's operations. The Time Critical
Targeting Functionality (TCTF) program combines the functionality of several tools aiding
in the prosecution of significant threats of fleeting vulnerability. As with any system, active
user involvement and Human Factors guidance are necessary to ensure a usable design. The
TCTF program applies these principles through several techniques including Applied
Cognitive Work Analysis, GUI Working Groups, Heuristic Evaluations as well as user
surveys. The basis for all these analyses is determining the correct information to display to
the user at the correct moment. This document illustrates these techniques, provides the
results and recommendations from the evaluations as well as providing lessons learned and
example surveys.
