iv v team background
IV&V Team Background
  • JAMSS is anengineering support company of JAXA and supports International Space Station (ISS) Japanese module development.
  • IV&V team has been involved in software independent Verification and Validation (IV&V) of safety mission critical system since 1998.
  • We had done IV&V for 10 kinds of project, 15 kinds of system (Onboard S/W of ISS module, Satellite, Space vehicle, ground S/W).

current work
Current work
  • IV&V for 3 space projects.
  • Developing new techniques and validating them.
  • Validating existent techniques
  • Research of strategic IV&V assessment with University of Hawaii (Prof. Dan Port)
    • Strategic IV&V planning model

Note: “Strategic” means activities contribute to achieving an overall expected outcome rather than addressing a particular issue or problem

ISERN 2005 @Noosa Head

future work
Future work
  • IV&V for space projects based on Strategic IV&V planning model and validate them.
    • Include IV&V cost model, IV&V standardization, benchmark test using common model, IV&V framework,
  • Assign new IV&V techniques for never tried area (operational requirement, reuse, COTS)
  • Investigation of accidents and malfunctions and measure value of IV&V attributes and techniques by systemization of malfunctions
  • Enhancement of software IV&V for other domains such as Automobile, Nuclear, airplane, medical, defense, etc…

ISERN 2005 @Noosa Head

expected benefits from isern
Expected benefits from ISERN
  • New technologies that are beneficial to software IV&V
    • Individual IV&V techniques (Testing, modeling,etc…)
    • Value based technique
  • Research results that are produced by other industry domains in order to compare to our result produced by space systems.
  • Research opportunities for IV&V technologies

ISERN 2005 @Noosa Head

contribution to isern
Contribution to ISERN
  • Clarify and identify issues on safety critical system development
  • Share data behind issues that characterize the solutions for each issues
  • Use of research results and report demonstrated status and validated results
