i take you have never heard of the V-model. basically you climb the waterfall back up to verify everything. most things that fly within the atmosphere are done that way. pretty sure NASA would do the same.
You can assume people here know what waterfall and the V model are.
Depends. I’ve heard management talk about agile and waterfall, but I’ve not heard even one manager say V model.
You’re right I haven’t heard of that model, but NASA has documented pretty well that it follows waterfall. https://appel.nasa.gov/2018/11/27/spotlight-on-lessons-learned-aligning-system-development-models-with-insight-approaches/
