"I've trained, coached and mentored hundreds of first-time managers who've gone on to become great managers and leaders. I know what it takes to develop a great manager. James and Mike have done a superb job capturing what you need to know and do on the path to being great at managing and leading others. This is the book I always wish I had to give to the first-time managers I've had the honor to develop."
