Meeting Cost Canon — what a meeting really costs, and the should-this-exist gate#

The first discipline of the meetings skill is treating a meeting as a purchase. Nobody would sign a $600 invoice without asking what it buys, yet a six-person hour at a $90 fully-loaded rate is exactly that — approved with one calendar click. This file documents the canon behind meeting_cost_calculator.py: why the price must be said out loud, why the refocus overhead is real, and why "no decision, no meeting" is the correct default.

The scale of the problem#

• Executives average ~23 hours a week in meetings, up from under 10 hours in the 1960s, and 71% of senior managers surveyed said meetings are unproductive and inefficient (Leslie Perlow, Constance Noonan Hadley & Eunice Eun, "Stop the Meeting Madness," Harvard Business Review, July–August 2017). Perlow et al.'s core finding: dysfunctional meeting cultures self-perpetuate because no individual meeting ever gets billed for its cost.
• Most meetings fail by design, not execution. Steven Rogelberg's research program (surveying thousands of employees and leaders) finds roughly half of meeting time is rated ineffective by attendees, and the strongest lever is what happens before the meeting: whether it should exist, who is invited, and what the agenda demands (Steven G. Rogelberg, The Surprising Science of Meetings, Oxford University Press, 2019).
• Deleting meetings works. Shopify started 2023 by removing all recurring meetings with more than two people (~12,000 events) and later shipped an internal meeting cost calculator that embeds a dollar figure into every calendar invite — a typical 30-minute, 3-person meeting priced between $700 and $1,600. The point was behavioral: people decline purchases they would have accepted as invites.
• Industry surveys agree on the waste. Doodle's "State of Meetings" report estimated poorly organized meetings cost businesses in the tens of billions annually across the US and UK alone; Atlassian's long-running "you waste a lot of time at work" meeting statistics put the average employee at ~31 hours per month in unproductive meetings. Exact figures vary by survey; the direction never does.

The refocus overhead (--include-refocus)#

The invite says 30 minutes; the attention bill is larger. Gloria Mark's interruption research at UC Irvine measured an average of about 23 minutes to return to the interrupted task after a context switch (Gloria Mark, Daniela Gudith & Ulrich Klocke, "The Cost of Interrupted Work: More Speed and Stress," CHI, 2008). A mid-morning meeting is an interruption for every attendee doing focused work, which is why the calculator's --include-refocus flag adds 23 minutes per attendee at the same hourly rate. It is an estimate — deliberately conservative (one refocus, not two) — and it routinely doubles the sticker price of short meetings, which is the point.

The gate: decision, agenda, owner#

The calculator refuses a MEET verdict unless three things exist:

1. A decision (--has-decision). Andy Grove's taxonomy separates process meetings (one-on-ones, staff reviews — scheduled, informational) from mission meetings, which exist to produce a decision (Andrew S. Grove, High Output Management, Random House, 1983). An ad-hoc meeting with no decision is a status update wearing a meeting's clothes — Grove's rule was that a mission meeting that produces no decision is a failure of the chairman, not the attendees. Status flows async: Amazon's practice replaces presentation meetings with a silently-read six-page narrative memo, and its "two-pizza team" rule caps the audience — both documented across Jeff Bezos's shareholder letters and his explanation that "PowerPoint-style presentations somehow give permission to gloss over ideas."
2. An agenda (--has-agenda). Rogelberg's finding is blunt: agendas per se don't correlate with meeting quality — prepared, question-shaped agendas do (see agenda_discipline.md). The gate checks existence; the agenda builder enforces quality.
3. An owner (--has-owner). Perlow et al. and Rogelberg converge here: someone must be accountable for the meeting achieving its outcome and for follow-through afterwards. A meeting nobody owns produces minutes nobody reads.

Missing the decision → ASYNC (the cheapest meeting is no meeting). Missing agenda or owner with a real decision on the table → NOT-READY: the meeting may deserve to exist, but not yet.

Why the verdict is ternary, not a score#

A 0–100 "meeting quality score" invites negotiation. Three verdicts with hard edges do not: ASYNC ends the conversation (write the memo), NOT-READY names exactly what to fix, and MEET prints the invoice — total cost plus cost-per-minute — so the agenda's timeboxes get budgeted like money. This mirrors Shopify's design insight: the number changes behavior only when it arrives before the commitment is made.
