What does it take to successfully lead and manage a business or a team? Management consultant and HR specialist Stephen-Elkins Jarrett and organizational development consultant Nick Skinner share their combined experience of how mastery of 15 key areas can help you drive your business, team, or even yourself to success. Presented using the acronym of BLOOD, SWEAT, and TEARS, this book, presented in three volumes, aligns some established models with common sense to give a practical view with tools and tips gained over years of working across different industries and sectors. At the heart of the book is the fascinating study of behavior, discussed through the SPECTRUM model of behavior, showing how by treating others in the way that they want to be treated, we can engage, develop, and lead them to achieve meaningful goals.
