How We Make Decisions at Coinbase

Summary

Armstrong lays out Coinbase’s three-step decision-making framework for high-risk decisions (long-term implications, costly to unwind). Low-risk decisions should be made unilaterally by the area owner. Core mental models:

Set the Parameters. Before deliberation, define: the decision date (deadline to prevent analysis paralysis), the revisit date (commitment period before re-evaluation), the people (decision makers, input providers, affected parties), and the decision type (binary, prioritization, or choice). High-risk decisions get multiple decision makers with veto rights; tolerable-cost decisions get a single decision maker for speed.
Deliberate with Structure. Enumerate options (quantity first, defer judgment). Present data as pre-reads. Conduct blind first-round voting. Discussion goes from least senior to most senior — critical for avoiding groupthink. Second-round voting captures updated perspectives after full information sharing.
Decide, Communicate, Memorialize. The decision maker takes a day or two after deliberation, then emails the decision to affected parties with rationale, options considered, and revisit date. Contentious decisions land better via async email (time to process). Save the spreadsheet permanently for post-mortems and to guard against history revisionists.
Failure Modes Taxonomy. Twelve anti-patterns including: “Lord of the Flies” (no clear decision maker until battle lines drawn), “Pulling Rank” (delegating then overruling), “Yes People” (senior voices swaying before others speak), “Accidental Yes” (email momentum of +1s without due consideration), “Analysis Paralysis” (hiding behind “let’s split test it”), “Unintentional Democracy” (decision maker abdicating to the vote count).

Relevance

06-reference/2026-04-03-peacetime-wartime-ceo — In wartime, you compress the decision framework. Fewer decision makers, tighter deadlines, less deliberation. The framework still holds, just at higher speed.

Open Questions

At what team size does a formal decision framework like this become necessary vs. overhead? Is there a solopreneur version?
How does the “least senior speaks first” rule interact with remote/async cultures where the room doesn’t exist?
