Efforts to complete the modules of the ATOS program in the top ten CMTs were also underway. ATOS module 7 (Analysis) and module 8 (Implementation) were developed using the System Safety Process Model (SSPM), as recommended by the FAA Office of System Safety. At the same time, another working group applied the model to the SEP program. Using the SSPM in SEP not only allowed a clearer risk analysis and targeting approach, other enhancements placed these activities in the initial planning phase. This is referred to as SEP module III. The use of a common system safety model in both ATOS and pre-ATOS CMTs brought the programs closer together and gave new capabilities to all CMTs.
