When the solution is simple, God is answering. Not everything that counts can be counted, and not everything that can be counted counts. When it modifies something, it refers to the way information is obtained by observation and generalized into a model that is as simple as possible yet can predict outcomes to an acceptable degree. When the model fails to predict outcomes acceptably, it is modified or replaced by another model. Such models are very useful for making decisions to achieve desired results.
Good management utilizes such models extensively, when suitable ones exist.
Repeatability is a very desirable guide. Frequently appropriate models that encompass the existing conditions do not exist because all of the conditions upon which they depend have not been identified. However, we usually have some models that seem to apply to similar conditions. They are appropriate as far as we know . All models are created with only some of the conditions identified, and thereby are only able to predict the average result, not individual results.
