The FRACAS shall then evaluate for quality and prioritize these candidate lessons and forward them to the Lessons Learned App

12、roval Authority (LLAA) for further consideration. If a Capability Level 4 FRACAS is required, the FRACAS shall also consider aspects of its own process that may constitute lessons learned candidates, submit the lessons to the LLAA for review and approval, and share the lessons with the FRACAS of oth

13、er projects throughout the enterprise. The FRACAS process shall meet annual improvement goals established by the project and institutional management. The improvement goals shall be directed at achieving a level of FRACAS process capability that is consistent with the level of residual risk acceptab

An independent assessment of the FRACAS process shall be performed at intervals not to exceed one year. This ass

Included in the output shall be metrics for the progress made in process improvements, and the id
