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).

ISERN 2005 @Noosa Head


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
