This is the trend toward increasingly elegant models. The term "elegance" here refers to the number of rules and distinctions a particular model requires to be able to account for all of the outcomes for which it has been designed. The most elegant model would be the one which employs the fewest number of distinctions and which is still able to secure a domain of outcomes equal to or greater than that of more complex models. For people and organizations, this means a significant saving of time and energy in the development and implementation of behavioral outcomes necessary to achieve their goals.

1. The transition of models toward increased elegance occurs in two ways:The elements identified as having casual importance become more basic to the particular interactions involved in achieving outcomes. In NLP, for instance, we begin by showing how the five classes of sensory experience (seeing, hearing, feeling, smelling and tasting) are the basis for the strategies people have for generating and guiding behavior, rather than more complex and abstract concepts such as "ego," "mind," "human nature," mechanisms," "morals," "reason," etc., employed by other behavioral models.

2. The orientation of the model turns much more toward form than content. By "form" we mean the principles or rules of interaction between structural elements that generate the possible states or interactions of the system. The basic equations or physical "laws" developed by Newton, for instance, are simple and elegant statements of the relationships between physical elements (at a certain level of experience) that can be used to describe, predict and prescribe the changing events that make up the content of a large portion of our physical universe. These same formal rules hold for the motions and interactions of many different objects: springs, billiard balls, pendulums, cars, projectiles and so on.
