Retail Change: a consideratici! of the UK food retail industry, 1950-2010. © Roger Clough 2002 Ph.D Middlesex University Abstract The immense changes to have taken place in UK food retailing during the second half of the 20th ccntury are detailed, explained and analysed, with constant référence to théories of retail change. The resuit is not just a history of UK food retail change post-1950, but a comprehensive évaluation and extension of retail change theory, with new driving forces and ideas elaborated, and a forecast of likely key developments to 2010. The thesis is based largely on the testimonies of key industry actors of the period, including past and présent executives of leading food retali organisations, and followed an un-structured interview approach, allowing stories to be told without unnecessary constraint. The development of the industry is detailed and explained, drawing heavily on thèse testìmonies, and this change is explained with référence to major factors with a direct hearing on the industry, such as government policy and socio-economie change. Because of the emphasis on witness accounts, the théories of retail change are analysed with a heavy focus on the people driving change, a refreshing change in a field where the historical nature of the subject tends to drive research towards secondary sources of data. The thesis contributes a better understanding of the forces driving the théories of retail change, and proposes an extension to the domain of application. The relevant éléments of the théories of retail change are implemented to forecast likely developments in the UK food retail industry to 2010, which is complemented by an 'expert' Delphi forecast and a projection of current socio-economie trends.

I could not have written it without their help, and the help of many people is evident in the text, while others have played a background rôle of equal importance. First, my thanks go to my académie Supervisors, Professor David A. Kirby and Professor Peter Newby, who directed me to my goals, provided insight, comment and help. Jennifer J.Tanburn played an equally important role, and was an excellent source of information and contacts, and I thank her sincerely. John Poppleton also helped with contacts, which I appreciate very much. Van den Bergh Foods kindly sponsored the project financially, for which I am extremely grateful and thank fui. Industry insiders were also major contributors to this work, and to them I am particularly thankful. I took up their time interviewing, surveying, surveying again, and generally bothering them, and 1 was pleasantly surprised by their kind response, given that the majority of them are busy and important people with demanding schedules. Thank you ail very much, particularly those who took part in the interviews and Delphi forecasting. I spent a lot ottime in Hbraries, particularly in the initial stages. In particular 1 must thank the staff of Middlesex University library, the IGD information unit, Shirley in particular, London School of Economies library, and the British Library. Last, but by no means least, my thanks go out to my family, who have been very supportive. In particular, I would like to thank my wife, Lucy, for her support over the last four years, and apologise profusely for ali the boredom I have inflicted! You are the final person that 1 could not have done this without, thank you. 1 Chapter 1 Introduction, Airas and Objectives 1.1 Introduction to change, retail change and general background "One aspect that distinguishes the second half of the 20th century from its first half is the speed of change in the political, economical, social and technological arenas. During the first half of the century, things had changed and developed fairly slowly and steadily; yesterday was like tomorrow. In the second half of this century, however, a number of events have taken place unexpectedly and trends have shifted in dramatic fashion. " [Ono and Wedemeyer, 1994] It is widely accepted that the second half of the twentieth century has been a period of relentless and unprecedented change [Drucker, 1977, 1986; Ono and Wedemeyer, 1994; Peters, 1989]. Not since the industrial revolution has such dramatic and widespread change taken place [Drucker, 1977]. The rate of change slowed between the world wars of 1914 and 1939, the inter-war years being a period when existing technologies and industries were built upon rather than disappearing into the shadow of innovation [Drucker, 1977]. A factor attributed to the slowing of the rate of change during this period was the lack of industrialisation taking place around the world [Drucker, 1977].
