NASA Systems Engineering Process
The Verification and Validation (V&V)phase includes measuring theperformance characteristics of data,information, technologies, and/ormethods, and assessing the ability ofthese tools to meet the requirements ofthe DSS.In the Benchmarking phase, theadoption of NASA inputs within a DSSand the resulting impacts and outcomesare documented in a Benchmark Report.
Use of Systems Engineering principles leads toscalable, systemic, and sustainable solutions andprocesses, which in turn contribute to thesuccess of the mission, goals, and objectives ofeach National Application.The Evaluation phase involves understanding therequirements for and technical feasibility of Earthscience and remote sensing tools and methodsfor addressing DSS needs.

Justification for RPC
• Demonstrate the utility of innovative solutions prior to budget support for operational use of missions.
• Significantly accelerate the evaluation of mission science results.
• Make budget support for a mission possible much earlier than under the current situation.

Capabilities
Performance Metrics Workbench
Provide tools to determine if there is significant change in model performance.
• Visualization of model results• Statistical analysis tools
May 17, 2006 May 17, 2006 19
Idealized Scenarios
Perform experiment using
• Multiple data sources and a single model
• Baseline data sources and multiple models
May 17, 2006 May 17, 2006 20
Limitations• Substantial programming of software is outside
the scope of RPC experiments, e.g. major modification of existing models
• RPC experiments will perform due-diligence systems engineering of limited prototypes. – Not the same as ISS
• RPC infrastructure (January 2008) will consist of two computational nodes, one at NASA Stennis Space Center and one at Mississippi State University.
• RPC (January 2008) will have one physical meeting facility at NASA Stennis Space Center.

Impacts
• Shift from ad hoc to a systems engineering approach for transitioning research to operations.
• “Steering committee” — Organizational mechanism for approving and prioritizing RPC experiments.
• “Experiment team” — Temporary multidisciplinary teams to facilitate and conduct the experiment.
• “Technical working group” — Multidisciplinary team to oversee the technical evolution of the infrastructure.

RPC Summary
• Infrastructure will provide a suite of tools
• Facility at NASA Stennis Space Center
• Experiments conducted during development (January 2006–December 2007) will illustrate the long-term potential for rapid effective RPC experiments.
• Design will allow replication of nodes at other locations.
