2、ption of Driving Event: From the inception of SL-3 until the flight, the experiment complement changed three or four times. These changes occurred during Payload integration and each time required the integration process to start over. This resulted in considerable manpower/money waste.Lesson(s) Lea
3、rned: Flight assignment of experiments without appropriate development maturity often results in severe impacts to the experiment and the integrated payload.Recommendation(s): Assignment of an experiment to a mission which is about to enter the payload analytical integration phase should be avoided
4、if the experiment has not reached as a minimum, the following milestones: 1) Experiment has completed the preliminary requirements review, including general requirements for integration, and is approaching the preliminary design review. 2) Funding for the completion of experiment development and man
5、ufacture has been committed. 3) The experiment schedule for preliminary design review, critical design review, and software review realistically supports the integrated payload reviews. That is, the experiment reviews should lead the ipl reviews by at least six months.Evidence of Recurrence Control
