When we develop a change our degree of belief starts off slow, because we have limited knowledge to support our test and our predictions. As we do more testing and discover what works and what doesn’t, as well as better understand the process we’re trying to improve, our degree of belief increases. When our change results in improvement, our degree of belief moves from low to medium. Testing under different conditions, different people, different times of day, different units, as well as testing what we don’t think works, expands our degree of belief and moves us to a change that results in improvement.
