For the purpose of this study, we wanted to work with companies in a well established industry where ISO registration was prevalent. Thus, automotive industry companies were sought, limiting our efforts to plants having experience with ISO 14001. An initial list of automotive suppliers was generated based on geographic proximity, a web based search of ISO registered plants, contacting managers at registered plants and recommendations from these same managers. Companies were identified or added to our sample during the process of conducting the interviews and were based on the recommendations of respondents. The sample in this study include automobile OEMs and Tier I suppliers. These plants and this approach to sampling fits well within Yin’s (1994) suggested research design, where replication is achieved by making sure the same methods are applied in each case so that the findings can be compared.
