David Pheasey started his working life as a mechanical engineer and worked as a production engineer for the Lucas Group in the UK. In the 1980s, computers were becoming powerful enough to run some of the systems we now take for granted and he became involved in the management of the implementation of material requirements planning systems. He then moved into a position responsible for materials management in a small but growing microcomputer manufacturing business. He later took responsibility for the commercial aspects of the supply chain and travelled to Asia and the US, sourcing and managing suppliers.
David joined Ingersoll Engineers in the early 1990s as a consultant specializing in supply chain. At that time, Ingersoll Engineers were one of the foremost implementers of cellular technology and David project managed several transformation programs involving the integration of people from functional departments into cellular and mini business organizations. In 2004, David and a long-term colleague, Richard Wardle, set up Demand Chain International, now part of the International Consulting Network.
