The 40-40-20 rule answers a question almost nobody is asking: how should a director actually spend their time preparing for, attending, and acting at a board meeting? Too many boards waste their limited time together listening to reports read aloud, reports that could have been distributed and read in advance.
The Three Parts of the Rule
The rule divides a director's total effort across a board meeting into three parts:
- 40%, Reading the reports before the meeting. Each director receives detailed written reports ahead of time and studies them, noting questions, disagreements, and anything that needs clarification. The reading is preparation; it does not belong in the meeting.
- 40%, Engaging in session. Two-thirds of the actual meeting time is spent engaging with the key operators of the organization about the information already delivered in those reports. If the person who wrote a report is not present, the CEO must be able to answer for it. No reading of slides is permitted.
- 20%, Deciding. The final third of the meeting is spent carefully considering the pending motions and voting them up or down. People tend to think this is all that boards do, but in truth it is the smallest slice, because most of the work was done in preparation.
Why the Math Looks Odd
Because a substantial part of the work happens before the room is ever called to order, the in-session meeting itself is only about 60% of the whole process. Two-thirds of that meeting (40% of the whole) is engagement; the remaining third (20% of the whole) is motions. Motions do not have to wait until the end, they can be raised throughout as each report is discussed, but across the whole meeting only about a fifth of the time is spent on the vote itself.
Demand Great Reports
You cannot run a 40-40-20 meeting without demanding great reports from staff. If the board packet is incomplete, poorly formatted, or late, the board chair must push back.
As a director, if you do not understand a report, do not stay silent. Write to the CEO in advance of the meeting: "I'm looking at the personnel deviation on page 3 and need more context before we vote. Could you provide a summary of the salary adjustments?" This saves meeting time and lets the CEO prepare a thoughtful answer rather than getting defensive in front of the entire boardroom.
