Human Factor as a discipline concerns the interactions between technology, organisation and humans. But it's more than meets the eye. From my background in the military we always strive to optimize "ability" and performance. That means we need to know how interactions affect performance and sustainability. When we add the aspect of operational psychology we can implement simple useful tools that can help us to manage stressors functionally and promote sustainability, health and performance. If I speak I will present examples from live situations when we used, a variety of tools that we have found are simple and effective enough to provide support for leaders as well as personnel. Based on that experience I will present a model that brings them together in a concept that is easy to teach, and use.
