The goal of this guide is to provide SEM professionals with relevant program references and resources for industrial SEM EUL. It focuses on program-level SEM EUL, not the EUL of specific actions to improve efficiency. It does so by summarizing NW program history for industrial SEM EULs and providing references and resources. Data from existing studies of industrial programs in the NW is included in Table 1. Evaluation and research reports providing EUL and measure persistence documentation are listed in Table 2. An annotated reference section is provided to assist SEM professionals in investigating the EUL for SEM programs, with both cited documents and relevant studies of interest to those assessing persistence.
