"In the context of improvement, a change is a prediction - if the change is made, improvement
will result. This prediction is made and a plan must be developed from it, even though no one
can foretell the future. The more knowledge one has about how the particular system under
consideration functions or could function, the better the prediction and the greater the likelihood
that the change will result in improvement. Comparing the predictions to the results is a key
source of learning. Skillfully building knowledge by making changes and observing or measuring
the results is the foundation of the science of improvement."
