"A good concept demands a sound definition. Definitions must be rigorously formulated, containing the necessary conditions that make the concept unique and unchanging in time and space.[iii] Furthermore, the conditions are not simple verbal crutches; they are the concept’s core dimensions. These features should be turned into specific differentiating factors that give the concept individuality. Factors are not only theoretical; they should be employed in practice. Differentiating factors should be turned into competencies that can train anyone in any context. However, the differentiating factors need to be necessary and sufficient. Because of this, they should be derived from a theoretical model of international actor behavior.[iv] This model should flow from a core premise, grounding the factors. Only after proposing a model and deriving core dimensions can we advance specific learning objectives, competencies, and methods for training strategists."
