The concept of 'OKness' is probably familiar even to people who have not read much transactional analysis (TA). This concept is the core of transactional analysis, both in terms of its philosophy, and of its contribution to the understanding of people and their interactions: the analysis of transactions. This article explores the extension of the existing two dimensional 'OK Corral' (Ernst, 1971), and Berne's (1972/1975) elaboration of the third-dimensional position in his last book, published posthumously.
