2、 Qualification TestingLesson(s) Learned: Node #1 was shipped to KSC before completion, and it is planned or anticipated that other ISS hardware will be shipped before qualification tests are completed. This disrupts the desirable continuity of effort and can lead to safety problems.Recommendation(s)

3、: NASA should assure that ISS assemblies shipped before completion of the manufacturing, testing, and qualification processes have been carefully scrutinized to make sure that no safety-related steps are subverted. Evidence of Recurrence Control Effectiveness: The generation, implementation and trac
