3、tablished and begin running smoothly. A manual, paper-based signoff process further hampered it.Lesson(s) Learned: To develop a fully functioning action/request for information process to support an accident investigation will take several weeks. Assure strong support to the CM organization because
4、until it is working, the investigation will be hampered.Recommendation(s): a71 Designate CM specialists to analyze and tune the various CM processes and sub-processes for improvements and efficiencies. The start-up phase for the full end-to-end CM process to support an accident investigation may tak
5、e 4-6 weeks. Additional CM personnel would probably speed up that startup inefficiency. After the start-up phase, the end-to-end CM process for a single action may still take on average around 3 weeks.a71 Designate a Board support member to ensure that Board members understand the CM processes, so a
