Great write-up, thank you!
From the prag prog, "Take small steps - always," is a similar idea.
They also mention tracer bullets, and the phrase "Ready, Fire, Aim!"

It might be another toolbox to add besides the strangler pattern. I use the strangler pattern all the time to replace old COBOL implementations and other code where there aren't many knowledgable people for.

The concept has been used in Germany (where it is called a Durchstich) since at least the nineties. A colleague of mine was responsible for replacing the core software for a building society. Completely new software, new development environment that we’d not seen before, the works. So they picked a use case, I believe it was a particular kind of deposit, and implemented that while the rest of the team got up to speed on the development environment. Steel thread throughout.

Still very obscure. Neither steel nor thread analogy helps with explaining a generic common sense approach.
