A tripwire is a simple device used to trigger an alarm or alert when someone crosses a specific boundary. It typically consists of a thin wire or string that, when disturbed, activates a mechanism. Tripwires are commonly used in security systems, military operations, and even in outdoor activities to detect intruders or wildlife. In addition to security, tripwires can also refer to a concept in project management and business. Here, they serve as indicators or warning signs that signal when a project is veering off course. By identifying these tripwires early, teams can take corrective actions to keep projects on track.
