Whiteboard Defense
An engineering culture criterion proposed by Mitchell Hashimoto, requiring engineers to be able to clearly explain at any time how the systems they deliver work and to defend their decisions. It is inspired by the whiteboard segment of job interviews.

Mitchell Hashimoto proposed the concept of "whiteboard defense," whose core claim is that engineers should be able to be asked at any moment to explain any customer-facing system they have delivered, and to defend their decisions.
Whiteboard defense is described as an engineering culture criterion, inspired by the whiteboard segment in interviews but reversed for self-examination in daily delivery.
The standard of whiteboard defense does not require remembering the specific implementation of every function, but rather explaining high-level design choices (why choose option X rather than option Y) and under what circumstances the system would fail.
Whiteboard defense is in the same line as the "bus factor" and "maintainability" goals in software engineering.
The video creator inferred: if people can answer whiteboard-defense-style questions, one result is that they truly build things, because their decisions have a basis and the system has logic; another result is escaping the soul-crushing feeling that "everything is junk code."
Whiteboard defense is regarded as a corrective mechanism: beyond pursuing speed, it reintroduces a rigid requirement for understanding, turning "can you explain it" back into a delivery standard.
