The Gemini Infra-Red Multi-Object Spectrograph (GIRMOS) is a high-resolution integral-field spectroscope and imager being built by a consortium of Canadian universities and institutions, along with the International Gemini Observatory (Gemini) and the Korea Astronomy and Space Science Institute (KASI). The team needed a cost-effective way to bring a degree in Product and Quality Assurance to bear on instrument development, but without availability of a dedicated team. Advice and support from the Thirty Meter Telescope (TMT) Systems Engineering Team enabled GIRMOS to tailor and scale the TMT approach to fit within the available resources of a much smaller project. This Failure Modes and Effects Analysis (FMEA) method more easily allowed geographically distributed subsystem teams to work independently within an agreed-upon FMEA framework that rolled up into a System-level analysis. The TMT FMEA framework reduced the effort involved in all the follow-on work that used the same data set, namely sparing analysis, reliability and uptime analyses, and accelerated life testing.
