422-10-00-007 (REV. -), GLOBAL PRECIPITATION MEASUREMENT (GPM) PROJECT RISK MANAGEMENT PLAN (08-OCT-2002)., The Global Precipitation Measurement (GPM) mission is not a typical single-spacecraft, Earth Science mission in that it is composed of a non-traditional constellation of satellites, as well as several ground elements. These ground elements encompass the mission operations and data delivery services, as well as the ground validation and calibration sites, data processing, and other terrestrial science data sources. The configuration of this system will evolve over time with new constellation missions and precipitation data sources contributing data streams, while others reach the end of mission life, no longer contributing to the global precipitation data. GPM is a complex system of systems, space-based and terrestrial, but is focused on being a low risk mission, especially with respect to technology implementation. NASA GSFC has embraced a continuous risk management philosophy and has placed expectations on projects to incorporate this practice in all elements and across their entire life cycle. The risk management approach contained in this document is based upon the Continuous Risk Management Practices defined by the Software Assurance Technology Center at NASA GSFC and is consistent with NASA NPG 7120.5A, NASA Program and Project Management Processes and Requirements and NPG 8000.4, Risk Management Procedures and Guidelines. Figure 1-1 shows the basic Continuous Risk Management process utilized.
