Appendix II: Case Studies of Selected
Projects' Implementation of Earned Value
ManagementTo get such results, management needs to obtain reliable EVM data from
EVM systems that adhere to the ANSI/EIA-748 standard for informed
decision making. Until project offices undertake a rigorous validation of
their EVM data, NASA faces an increased risk that managers may not be
receiving the information they need to effectively manage their projects.
The following information describes the key that we used in tables 5
through 14 to convey the results of our assessment of the 10 case study
projects' implementation of EVM practices.Global Precipitation

* Project formulation start: July 2002
. Project confirmation date: December 2009
* Initial total project cost: $975.9 million
* Current total project cost: $932.8 million
* Launch readiness date: June 2014The Global Precipitation Measurement (GPM) mission, a joint NASA and
Japan Aerospace Exploration Agency (JAXA) project, seeks to improve
the scientific understanding of the global water cycle and the accuracy of
precipitation forecasts. The GPM is composed of a core spacecraft
carrying two main instruments: a Dual-frequency Precipitation Radar and
a GPM Microwave Imager (GMI). GPM builds on the work of the Tropical
Rainfall Measuring Mission, and will provide an opportunity to calibrate
measurements of global precipitation when it launches in 2014.
This analysis focuses only on the GMI-1 effort. Ball Aerospace and
Technology Company is the prime contractor for GMI. GMI's current
contract value is $217 million, which represents approximately 23 percent
of the total GPM project budget of $932.8 million. The GMI instrument
was delivered to Goddard Space Flight Center in February 2012 for
integration into NASA's upcoming Earth science spacecraft. All remaining
effort for GMI-1 is post delivery support, which is all level of effort.4 The
GPM project provided EVM reports for the entire project, but we did not4NASA was also developing a second Microwave Imager instrument for flight on another
spacecraft-GMI-2-that was descoped from the project in 2012. However, the science
requirements for GPM can still be met without flying the GMI-2 instrument.GAO-13-22 NASA
