When leadership decisions become complicated, the OBM Compass helps leaders determine not merely what they can do, but what they should do, why it matters, what evidence supports it, how people will be affected, and whether the result can be sustained. OBM is formally concerned with applying behavior analysis in organizations to improve performance and working conditions. The Compass gives that science a clear leadership and ethical orientation that can travel beyond traditional OBM audiences. Grounded in Organizational Behavior Management, behavioral science, leadership experience, difficult lessons, and more than twenty-five years of observing what organizations do to people and what people can accomplish when organizations are designed well. At the center of the compass is Purpose. Around it are four commitments: Evidence. Integrity. Compassion. Excellence. The OBM Compass is not a collection of attractive values intended for a wall. It is a decision system. Evidence asks: What is actually happening? Integrity asks: Are our actions consistent with what we say we value? Compassion asks: How are people experiencing this system, and what conditions are influencing their behavior? Excellence asks: Will this decision produce meaningful, reliable, and sustainable improvement? Purpose asks the question beneath all the others: Why does this matter?
