Philosophically, improvisation often focuses on bringing one's personal awareness "into the moment," and on developing a profound understanding for the action one is doing. This fusion of "awareness" and "understanding" brings the practitioner to the point where he or she can act with a range of options that best fit the situation, even if he or she has never experienced a similar situation. The study of the skills and techniques of improvisation can strongly influence ones competence in business, personal life, and/or in the arts.
