Who signs off in a multi-step approval chain?
Our single-reviewer setup just collapsed. Agents now draft the whole lifecycle program, and a pricing-change announcement needs finance on the numbers, legal on the terms language, and lifecycle on the segment math — while a routine onboarding variant needs none of that. One approver can't cover all three; three approvers on everything would grind us to a halt.
So we're designing a real chain: multiple signers, clear ordering, after-hours coverage. The failure I'm most afraid of isn't slowness, it's the chain getting bypassed within a month because it treats a typo fix like a pricing announcement. How do you route different risks to different signers without building a committee for every send?
Express the chain as a routing table, not a meeting. Each send type maps to a signer set: lifecycle-only for onboarding variants, lifecycle plus finance for anything quoting prices, lifecycle plus legal for terms-adjacent claims, everyone plus an executive override for pricing changes and crisis mail. Order by dependency — segment math first, then numbers, then language — so nobody re-checks another signer's domain. After-hours coverage comes from named deputies with identical authority, every delegation logged. And track approval latency per send type weekly; slow chains get simplified, not resented.
The chain has to protect the reviewers, not just the recipients. Sign-off should record exactly what was reviewed — draft version, segment definition, claims checked — so accountability survives people changing jobs and disputes six months later. My biggest leverage point: pre-approved language libraries for guarantees, security claims, pricing frames. Anything assembled from approved blocks gets light review; free-drafted copy gets the full chain. The nightmare isn't a slow chain, it's an undocumented one.
This is also how you keep experimentation alive. Tier the chain: pre-approved templates and locked claims ship on lifecycle-only approval, while novel claims, new segments above a size threshold, and cross-functional content escalate upward. And batch — have the agent queue a day's variants for one review session instead of interrupting signers per send. If every subject-line variant needs three signatures, testing dies and the program delivers governance theater instead of growth. Speed is a feature of chain design, not its enemy.
Design for the bypass, because there will be one. Every emergency send needs friction plus a trail: a written reason, a retro review within 48 hours, a named owner for the consequences. If bypasses cluster around one signer or one send type, that's data — the chain is miscalibrated, not the people misbehaving. And leadership has to visibly wait for approvals on its own pet campaigns. Culture eats checklists.
Tiered chains with pre-approved blocks carrying light review and novel claims escalating upward. It resolves the OP's core tension — rigor where risk lives, speed everywhere else — and the batching suggestion answers the signer-fatigue problem the routing table alone doesn't solve.
Why this one: it synthesizes the Operations routing table and the Legal language library into something a team can actually operate, with experimentation survival as an explicit design goal.
Publish a routing table mapping send types to signer sets, order reviews by dependency, pre-approve language blocks to keep routine variants fast, name deputies for coverage, log every decision with its draft version, and make bypasses documented and retro-reviewed. Calibrate with weekly latency data.
