The full phase spine — Analyze, Document, Design, Approve, Code, Deploy — with per-phase gates. Signals wire to deltas both ways: motivating in, validating out. Built for the weekly release cadence.
Every delta starts with a motivating signal. No more "why are we building this again?" halfway through.
Notion-shaped doc anchored to the change. Sections get comments. History is versioned.
Both sign before Approve unlocks. No more "we shipped what?" surprises at demo day.
Team-split + estimate before code starts. EM's gate is scope, not implementation.
The metric that motivated the delta is also what validates it. No hand-picked KPIs post-hoc.
If /checkout slows down after your delta, the alert pings you — not on-call.
"Our PM, designer, and tech lead used to be the three people most out of sync on any given change. Now the delta is the single place all three of them look — nobody's working from a stale copy."
Trunk is $29 per seat, all-in. Design, documentation, live analytics, journey mapping, feature flags. SSO on Team plan.
