You want to go to mars You spend 3 months designing a rocket You spend 6 months building a rocket You spend a month testing the rocket and notice there is a critical desing flaw.

You start over again with a new design and work on it for 2 months You spend another 6 months building it You spend 2 months testing

Rocket works fine now, but multiple other companies already have been to Mars, so no need to even go anymore.

This is the perfect waterfall analogy.

I'm glad I'm not alone. I couldn't make sense of this comic.

pretty sure they're saying waterfall for building a rocket because that's literally how NASA builds a rocket, including the software. It's terrible for building anything other than a rocket though, because the stakes aren't high for most other projects, at least not in the way that a critical mistake will be incredibly bad.

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.
