We have built many projects, and we believe the most valuable summary indicators are:
• Dτ = Delivery lead time. Product teams may say "from concept to customer" or "from idea to implementation".
• Dμ = Delivery service rate. Devops teams may say "deployment frequency" or "we ship X times per day".
• Dε = Delivery error ratio. Quality teams may say "change fail rate" or "percentage of rollbacks".
• Rτ = Restore lead time. Site reliability engineers may say "time to restore service" or "mean time to restore (MTTR)".

In fact, the dental-office “badness” of so much of the A.I. art is precisely why I don’t dispute Alexander’s assertion that people preferred it. Like any LLM output, A.I.-generated images are designed to please, not to provoke. [I’ve argued before that these images are, by their nature, almost unavoidably kitsch](https://maxread.substack.com/p/what-ai-art-spiral-images-tell-us)--comforting, straightforward, accessible, flattering. And people love kitsch!
People Prefer A.I. Art Because People Prefer Bad Art

To achieve that braking safety, the subway’s signal architecture works around the principle of ‘two-block control.’ Every track on the subway is cut up into blocks, electrically isolated sections of line that can detect occupancy by sending current through the axles of passing trains. In two-block control, the signal system keeps at least one unoccupied block – really, however many blocks you need to provide that braking distance with a margin for error – between one train and the next.
