thanks for sharing, some quick thoughts as I scan this…
• many people, myself included will likely trip up on Efficiency as it’s usually associated with cost discipline rigor. as currently written, the efficiency rubric reads like a subset, or a nuance, of speed. i would also consider how much perceived value the current definition of efficiency has for your customers in a business or a technical sense as the wall-clock savings may not be as material
• i do like the concept of safety, policy may be a trigger word in some engineering cultures. i know many platform customers (product teams) may see that as a turn-off. guardrail may be a better fit in some environments but it’s also prone to the same challenges as policy
• scalability comes across as onboarding time. i am not sure if that’s the intent behind it. maybe it needs better framing?
• i would probably try to align the “one metric that matters” with a guardrail metric that tells you if the current measurement is on or off track. i’d also consider explicitly enumerating how each of these metrics maps to internal technical and business goals / outcomes so teams can clearly see the sometimes hidden, or implicit, connection in how they help influence and impact the business
i hope this helps
