Since then a handful of companies have supported similar programs, among them ARCO, Beckman Instruments, Bristol-Myers, Eli Lilley, Kaiser Aluminum and Chemical, Monsanto, Procter & Gamble, Rohm and Haas and Standard Oil Company. In Europe, most of the efforts in oral history have been confined to non-business activities, where its use is relatively widespread in sociological and straight historical research. In a rare business-type project called "City Lives”, the National Life Story Collection attached to the British Library Sound Archive has been interviewing about 100 top men and women from financial institutions who have lived through the changes since WW2 (http://www.bl.uk/reshelp/findhelprestype/sound/ohist/ohnls/nationallifestories.html). Aside from that, only a small number of British companies have undertaken projects to record the memories and experiences of their employees, among them London Transport, which has made a special effort with their West Indian workforce, the brewers Bass, the telecommunications company Cable & Wireless and, until the project was aborted in 1991 as a cost-saving exercise, Ford UK. The uses to which they have put the information have generally been for museum exhibits or public relations. Modern oral debriefing is an enhancement of the old-fashioned prescriptive and formulaic exit interview, which is typically not an interview at all, rather the output of a formulaic questionnaire that attempts to uncover why employees – usually lower hierarchy workers - leave. The oral debrief has been sophisticated to the extent that its output is now a powerful means of extracting from individuals valuable knowledge that can be used to improve on past performance. The most accomplished practitioners are the US military, which has developed vast archives of oral testimony of wars since WW2 specifically as an educational tool for successive generations. The Department of the Army, for example, calls the process the End of Tour (EoT) interviews, which are conducted with departing commanders to make interviews available to their incoming replacements so that individuals can better understand the issues faced by their predecessors. Equally, companies such as Ford, ARCO, Beckman Instruments, Bristol-Myers, Eli Lilley, Kaiser Aluminum and Chemical, Monsanto, Procter & Gamble, Rohm and Haas and Standard Oil Company have also initiated programs of oral history but their application in decision-making is tentative. The oral debriefing usually centres on the issues and decisions unique to the organization and can be especially instructive as a decision-making tool. With senior decision-makers the most common candidates, such debriefings are always conducted near the end of a person's tenure, although some practitioners are now using it on a more regular basis and in project management.
