Emer Mc Carthy (my colleague, friend and co-author) and I just published 'Tight-loose' - a kindle book about performance management for people managers. It is a tiny book that you'll read in an hour. It is based on our experience and results. It is practical and the techniques do work. We believe it can really help develop a high performing team. And your team will thank you (well, they might).
We've two more books on the way. The first is "Go Conquer" which explains how we created 48, the challenger youth brand.
The other is a marketing book that looks at the marketing and creative process through the lens of a client (as opposed to the creative agency).
