A framework and a practice.
Teams don't adopt these metrics overnight; they ascend through them.
DORA's single most powerful rhetorical device was its maturity tiering. Elite / high / medium / low gave teams a self-locating language and an aspirational ladder. R.I.V.E.R. needs the same — five levels, each defined by what the team has achieved, not by what it lacks. The ladder is also a calibration target for the qualitative research: interviews will teach us what these levels actually look like in the wild, and where the transitions are hardest.
The team ships reliably on a DORA foundation. Delivery hygiene is in place — deployment frequency, lead time for changes, change failure rate, and time to restore are tracked and trending in the right direction. This is the foundation of a good release practice.
Deploy and release are separate events. The team rolls out progressively, targets specific cohorts, and can reverse a release in seconds without a redeploy. Release-layer metrics exist but aren't consistent across teams or releases.
Before a release ships, the team states what it expects to happen — hypothesis, success signal, target cohort, time horizon. Some releases get measured against what was declared. The discipline is emerging, not yet uniform.
Outcome attribution is systematic. Most releases carry a declared success signal and are evaluated against it after the fact. Not every hypothesis will hold — and that's the point. The team builds a durable record of which intents realized and which didn't, and can report Outcome Realization Rate in skip-levels and planning reviews with the evidence to back it.
Evidence from realized and unrealized intents feeds the next cycle. The team's predictions sharpen over time, not just its measurements. This is the compounding loop — the "Evolution" in R.I.V.E.R.
The level names and descriptions are draft v2 — revised from an earlier set that leaned on framework-internal vocabulary. The verbs (Deploy, Control, Declare, Prove, Learn) are meant to be self-locating even for readers who haven't seen the rest of R.I.V.E.R. The level descriptions will be calibrated against real practice through the Phase 1 qualitative interviews.
