From page 29...
... AWIPS risk management initiatives to date have been effective in reducing developmental risks. As discussed in Chapter 2, the WFO-Advanced prototype was an attempt to mitigate risk by demonstrating the technical feasibility of programming advanced operational algorithms for AWIPS.

From page 30...
... Recommendation. A realistic operational test of the contingency plan for failure of the master ground station should be planned and conducted well before AWIPS iNWS is reviewing the possibility of relocating the master ground station antenna to the roof of NWS headquarters in Silver Spring, Maryland, to reduce or eliminate the possibility of some failure modes for the SBN uplink.

From page 31...
... Recommendation. If improvements in the Build 3 time frame do not bring NCF performance up to operational standards, the AWIPS program should begin a risk reduction program to find a systemic solution to NCF performance problems.

From page 32...
... To assess NCF performance and evaluate the NCF design concept, particularly as the number of active nodes in the AWIPS network increases, current or alternative NCF operations to perform designated emergency recovery functions should be tested under realistic conditions. SITE BACKUP AND RECOVERY AWIPS is designed to operate as a system of interoperable nodes.

From page 33...
... Some form of periodic "drill" to test vendors' capability to replace system-critical hardware within the contractually agreed upon time should be included in the AWIPS risk management plan. MALICIOUS ACCESS AND EXTERNAL THREATS The risk management plan should include contingency plans for potential threats, such as unauthorized computer users (hackers)

From page 34...
... Recommendation. Detailed contingency plans for countering external threats to the integrity of the AWIPS system should be an integral part of the AWIPS risk management plan.
