2、t of the components that comprise the NASA Ground Network that supports the ADEOS-II mission were provided to the NGN as contributions from operational entities under the management of various NASA organizations. This approach presented both opportunities and challenges during the ADEOS-II NGN devel
3、opment and early operations. The one lesson learned in this regard with respect to managing the contribution of system components by various organizational entities is summarized below. It should be noted that ADEOS-II is a international partner mission, with the Japanese Space Agency (NASDA) as the
4、 mission lead. NASA provided NGN ground system support through an MOU with NASDA.Lesson(s) Learned: Engage Operational Component Management in Integration and Testing.Integration of NGNs many components was a challenge both in terms of the management of the system-to-system interfaces and in the man
5、agement of lines of authority and reporting for the various organizations involved. One of the methods used to manage this complexity was to charter a quarterly review panel consisting of “stake-holder” participants with management authority of the various NGN components. The actual ADEOS-II review
6、panel consisted of stake-holder participants from NASA/GSFC Code 450 (ground station and CSOC responsibilities), NASA/GSFC Code 420 (EOS-G Program Office), NASA/GSFC Code 423 (DAACs and networking), NASA/GSFC Code 290 (networks), NOAA/NESDIS (real-time interfaces). Code 300 (quality assurance) also

The quarterly review panel was declared a success and disbanded after the successful ADEOS-II NGN Operations Readiness Review held in September 2002.Recommendation(s): Engage O

Engage managers from operational components in the integration and test phases when re-using operational components in the development of ground systems for new missions.2.
