Andy Last has spent 20 years advising some of the world’s biggest businesses on social issues. In his new book, Business on a Mission, he explores the link between social mission, purpose, sustainability, and performance. Andy shows that purpose and profit are not incompatible, and that understanding, responding to, and actioning the values of a business can drive returns alongside attracting and retaining talent. In this interview, I speak with Andy Last, author of Business on a Mission, on the importance of social mission for businesses, how to articulate and measure your mission, and how social mission can drive real profits and performance.
