This was a talk delivered at Lead Developer London 2018, on Thurs 28/6/18. Talk title: "Teaching New Tricks – How to enhance the skills of experienced developers" Blurb: It’s easy to forget what it felt like when you were a beginner. This lively dog-based* talk is about the rewards and pitfalls involved in introducing pair programming, TDD and an agile development approach to experienced developers who are used to working in a different way. It includes several practical suggestions of how to help and convince less agile-experienced colleagues. Based on my experience as a consultant technical lead, the aim is to help you to move your team members to a state of childlike fearlessness where learning is fun; is embedded in everything you do; and applies to all team members regardless of experience. *It turns out that images of dogs can be used to illustrate an astonishing variety of concepts!
