Each Saturday we have a special treat – two editions of ‘Company Casebook’, our half-hour business documentary series where we go behind the scenes of interesting companies both large and small, looking for the human stories behind the financial numbers and analysing the who, why, where, what and when of business at the sharp end. Company Casebook is presented and produced by the hugely experienced Linda Lewis who worked at the BBC for many years, including a spell as presenter of PM. Each week Linda visits two businesses to find out about their vision, their strategy, and how they are faring in today’s competitive marketplace.
