![]() "NASA embeds quality assurance throughout the entire software lifecycle," says Crumbley. "Therefore, from a software lifecycle cost perspective, software testing becomes a large part of our budget." "Approximately 40-50% of the total software development project lifecycle cost involves testing, which is in line with industry software cost models," says Crumbley. In other words, some testing activities at NASA are the same as for us groundhogs, while other aspects apply uniquely to their high-stakes missions and environmental concerns. ![]() "I expanded my knowledge from electronic parts to assemblies, and then to supply chains, and found my way to having a view of all hardware manufacturing." " I have studied how things fail, which has to do a lot with how they're built and their manufacturing process attributes," says Plante. Plante started working at NASA in 1987 as an electrical parts engineer. I have a background in electrical engineering parts and assemblies." "This includes launch vehicles like SLS space launch systems, and processes like welding. "The scope of my domain is mission hardware: space flight and aeronautics hardware," says Plante. “I was primarily in the engineering side of the house for 31 years and then in early 2019, I moved to OSMA to improve and automate how we do software assurance." "Most of the mission software is mission-critical and often also safety-critical." -Tim Crumbley, NASA Software Assurance Technical FellowĬrumbley started at NASA in 1987, working on the International Space Station (ISS) and its software development. I had the pleasure of chatting with two NASA test and QA testers: Tim Crumbley, Software Assurance Technical Fellow, who supports the NASA headquarters OSMA (located at NASA's Marshall Space Flight Center in Alabama) and Jeannette Plante, Quality Engineering Technical Fellow, who also supports OSMA – she works on Hardware Assurance – located at NASA headquarters in Washington, DC. Testing and QA within NASA is handled by a mix of dedicated departments, including the Office of Safety and Mission Assurance (OSMA). ![]() Your mission, should you choose to accept it… space agency’s methods can help not-for-space testers and QA practitioners. What makes NASA's testing requirements unique? Here’s a take-off point – and how the U.S. That’s what it’s like for QA testing at NASA – and it applies to equipment such as rocket engines, fuel mixes, satellites, space habitats, as well as to ordinary computer software and hardware. But imagine the scenario when lives are at stake, and when embedded flaws can be expensive or impossible to fix. But that comes with additional concerns, such as lives at stake and too-far-to-repair constraints.Įvery quality tester worries about the cost of missing defects. It is, perhaps, your dream job – doing software testing for positive world-changing applications such as space exploration.
