Trial advocacy originally focused on individual actions within the trial, proposing methods for improved selection of jurors, delivery of argument, and direct and cross examination. However, in the 1970s, NITA advanced the concepts of theme and theory as methods of integrating the various components into a cohesive whole. More recently, litigation strategy has blossomed with the importation of concepts from economic game theory, complexity theory, Gestalt psychology, and the application of maneuver warfare as a means not only of integrating the various actions within the trial into a comprehensive case, but also as a means of gaining a decisive advantage over opposing counsel.
