I appreciate your candor about not wanting to speak on topics outside your expertise. That's commendable. I wonder if we can still talk with the understanding that we may not know it all. I truly believe curiosity is able to sidestep many of the problems related with ignorance.

You're right to be cautious about appeals to authority. My intention wasn't to suggest NASA's use of Agile validates it universally, but rather to counter the OP comic's implication that Agile is inherently incapable of achieving significant goals like space exploration.

Regarding Agile-like practices in earlier NASA projects, you're correct that concrete evidence is limited. However, we can analyze their approaches through the lens of Agile principles. Scrum, for instance, aims to foster characteristics found in high-performing teams: clear goals, information saturation, rapid feedback loops, adaptability to changing requirements, and effective collaboration. These elements aren't exclusive to Scrum or even to modern Agile methodologies. The key is recognizing that effective project management often naturally gravitates towards these principles, whether formally adopting Agile or not.

It's an interesting area for further research: have complex engineering projects historically incorporated elements we now associate with Agile? If so, how?

Your skepticism is valuable in pushing for a more nuanced understanding of project management across different domains.
