Case Study: NASA ECS Functional Test Management

 
Customer: NASA Goddard Space Flight Center,
Flight Projects Directorate,
Earth Sciences Projects Division
(Raytheon Company, prime contractor)		 NASA
Goal: The ESDIS (Earth Science and Data Information System) Project manages the science systems of the Earth Observing System Data and Information System (EOSDIS). EOSDIS provides science data to a wide community of users for NASA’s Science Mission Directorate
Application: The ESDIS Project is responsible for:

  • Processing, archiving, and distributing Earth science satellite data (e.g., land, ocean and atmosphere data products)
  • Providing tools to facilitate the processing, archiving, and distribution of Earth science data
  • Collecting metrics and user satisfaction data to learn how to continue improving services provided to users
  • Ensuring scientists and the public have access to data to enable the study of Earth from space to advance scientific understanding and meet societal needs.
Challenges: Capturing high-volume observational earth science data across 12 different observing platforms with a heterogeneous mix of satellites, radar, sensors, models, and systems
FTI’s Approach: Perform sustaining engineering activities on the SDPS software baseline in accordance with Raytheon policies and procedures:

  • Support maintenance of existing system software, developing or modifying application programs for operations ranging from routine to complex to highly specialized.
  • Manage functional software test lab and test fixes for complex software systems
  • Generate test requirements during design, code, unit test and integration for subsystem components as required based on NCRs generated by the customer including Severity 5 NCRs
  • Develop scripts and tests for Software Functionality Lab
  • Support Integration and Regression Tests for new software releases
  • Utilize structured programming techniques and methods for all SDLC phases, including requirements, software design, software coding and testing, integration, and acceptance testing.
  • Utilize current software development techniques that exploit latest advances in computer technology to produce fast executing programs
  • Adhere to Raytheon Software Development processes
  • Provide code estimation support, as required.
Products Used: Red Hat 5 Enterprise Edition, Ubuntu 8.04, Magic Service Desk, LANDesk, C, C++, Java, Scripting Languages: Perl, C Shell, Korn Shell, Sybase, Eclipse IDE, Netbeans, Apache Tomcat Web server, ClearCase
Benefits:
  • Advance understanding of the entire Earth system — the atmosphere, the land, the oceans, the cryosphere, and the solar driving force
  • Provide improved project performance (“better, faster, cheaper”)
Delivery: On time, within budget. CMMI Level 3 project.
