This document discusses five clever debugging techniques for LabVIEW developers: 1) using probes effectively, 2) suspending the virtual instrument when called, 3) using debug panels, 4) implementing unit testing, and 5) tracing program execution with history probes. It notes that debugging is not a value-added task and can lead to schedule delays, increased costs for customers, and negative perceptions of quality. The final slides take a deeper look at each technique and address common questions.
