    Later this year in partnership with The Educational Academy and Routledge Publishing we are introducing a new structured continuing professional development programme for Sales Professionals, globally.

    Drawing on the leading research and global, best practices in sales and sales management it is based upon Professor Marshall’s bestselling books, co-authored with Professor Mark Johnston, Sales Force Management (now published in its 11th edition) and Contemporary Selling: Building Relationships, Creating Value (now published in its 4th edition). Both books are recognised as the most up-to-date textbooks on selling and sales management available anywhere in the world today.
