The John Lewis Partnership has announced a number of senior management changes and appointed a group productivity director.

The company’s retail director, Andrew Murphy has been chosen for the newly created role of group productivity director, where he will work closely with the chairman's committee and partnership board to develop plans that will support the John Lewis’s productivity improvements, financial strategy and the future organisation structure.

John Lewis partnership chairman, Sir Charlie Mayfield said, “The rapid rate of change in retail is set to continue and therefore the time is right for us to develop the thinking that will help sustain the Partnership in the next generation and I am delighted that Andrew has agreed to take up this new role. His appointment is part of the plans we are putting in place to deliver the Partnership's strategy in the next five years and follows the announcement of Tom Athron's appointment as group development director in June 2015.”

Online director Mark Lewis has succeeded Andrew Murphy as retail director and will take responsibility for both online and shop operations. Meanwhile Dino Rocos, who is current responsible for supply chain and merchandising, will become operations director and will also take on responsibility for omni-channel customer ordering, contact handling and health and safety.

Buying and brand director, Paula Nickolds will become commercial director and will lead the development of John Lewis’s future proposition including new store formats.

Finally, Craig Inglis, who is currently marketing director, will take up the new role of customer director with his responsibilities now including the end-to-end customer experience although he will continue to oversee marketing and customer insight.

Managing director of John Lewis, Andy Street, said: “These important changes to the John Lewis Management Board place the customer at the heart of our decision making. The new John Lewis Board composition will ensure we continue to lead omni-channel retailing in the UK.”
