This chapter starts with an exploration of what underpins a Developmental Transactional Analysis (DTA) approach to coaching supervision. DTA has an ‘I’m okay, You’re okay’ foundation. A stance that says ‘I value you as a human being, and I invite you to value me in the same way’, and which allows for positive challenge; for example, ‘I value you as a person and there are aspects of your behaviour which I invite you to change’. It looks at the role of the coach supervisor in this context, and how the practitioner might prepare themselves to work congruently with the approach. Supervisees often bring to supervision moments of their client work when they experience being out of the ‘I’m okay, You’re okay’ life position. Through supervision they can identify how they might invite, unconsciously, responses from others which develop into psychological games. By making more informed choices to change their behaviour they will give out different, more positive invitations enabling smoother interactions with their clients (and others). The chapter closes by looking at what else should be considered before working with the techniques, approaches, enquiries and experiments that follow. In this chapter there are 11 ‘techniques’ written by seven different contributors.
