"I genuinely don't believe you can build complex systems any other way..."
I wonder how much battery, inverter, grid forming etc one could put in a standard 2TE container sized box, build one a week, and plug together somewhere convenient.
One might not add much inertia to a Grid, but as the year goes by you'd be steadier and steadier.
Yeeaaa... it's a different approach.
(Don't read this as a defence of Musk, he's a turd, but SpaceX has competent technical people below their chimpanzee-on-a-string PR person)
NASA's traditional approach was to basically achieve perfection of design and manufacturing before trying to launch anything. Look at every possible failure mode of every component, down to the tiniest screw or wire or bit of plastic. Keep redesigning parts until you eliminate all failure modes that you don't have triply-redundant backups for. Test the living snot out of everything on the ground, in the lab. Have massive technical and safety reviews to ensure nothing was missed, anywhere.
It worked about as well as anything could, but it was extremely slow, bureaucratic, and above all incredibly expensive. Tons of rework when issues were found meant having to go back 3 steps to change something, and then redo the massive amount of work that had been done since then to make sure no new failure modes were possible, etc.
SpaceX is doing things differently - #iterative design. You design, build, #integrate, and #test-to-failure as often as possible to learn where the weak spots are -- you then rapidly iterate when you find the problems. "Rapid Unscheduled Disassembly" is an expected part of the process - it's how you learn the limits of what you've built, where the problems are.
Neither one is "the right way". They both work.

All progress here is iterative, currently waiting patiently for some components to setup the DC power system in the house , primarily for an led lighting system 😁

Moments away from opening my Professional Scrum with User Experience course. (PSU)
It's one of my favourite courses to teach. The material is important for everyone who attempts to blend #UX and #Iterative&Incremental #Software #Development.
Some dancing starfish for today's #inkyDays drawing. With my recovery from surgery, I can't really dance yet, but I'm dancing on the inside.
Here's an in-progress shot.
And that's a wrap for this month's daily drawings. In-progress and complete drawings for this month are now all posted for my supporters on patreon and kofi in this month's #inkyDays posts:

I used to work on the IT team of a government service. Since #government usually is the only provider of its services, as a citizen, I am also a customer of the service I worked on.
I'm always pleased to see my successors carrying the same #usability torch I did, as evidenced by further #iterative improvements.
It's in good hands, and the process works. Makes me happy.
