'The Right Stuff' - that multifaceted quality of piloting skill, courage, experience, nerve and reflexes - was a term coined by Tom Wolfe. It describes the common attributes of the pilots who made the Mercury 7 space programme a success. The Mercury programme was a challenge of tremendous complexity and scale - any team facing a similar design challenge draws upon a mixture of experience, skill and personal qualities to face that challenge. Why do some practitioners fail to live up to their potential, while others perform far beyond our initial expectations? What qualities and behaviours enable teams to rise to the occasion? In this session I'll talk about the things I've learned building and leading design teams over the past 15 years and how there are echos from the themes of 'The Right Stuff'. It's aimed at practitioners and managers, with the goal of communicating some of the qualities and attributes I've found to be leading indicators of individual and team performance.
