Because the presenters knew their material forward and back, they experienced what social psychologists call “the curse of knowledge”—the cognitive bias that makes it difficult for them to remember what it’s like to be a beginner seeing the content for the first time. That’s why they assumed the room could quickly grasp all the salient points as they flipped from slide to slide.

But if the goal of the meeting is to make decisions or give feedback, it can be tough for stakeholders to understand the material well enough in the span of a single meeting to arrive at thoughtful conclusions.

The solution is to help everyone come prepared. The change we made to our decision and review meetings was to ask the organizers to send out any presentations or documents the day before so that everyone got the chance to process the information in advance. This meant that I could spend as much time as I needed to understand all the charts and graphs, which allowed me to be a better contributor in the meeting.

If a company-wide meeting attended by five hundred employees isn’t engaging or memorable, then the company will have wasted five hundred people-hours—ten thousand dollars if you assume a twenty-dollar-per-person hourly wage. Spending even five hours of five people’s time (five hundred dollars total) to prepare for that meeting is undoubtedly worth it. Even one recurring weekly meeting with a handful of attendees can translate to thousands of dollars of wasted productivity over the course of a year if that time together isn’t well spent.

After the meeting, the follow-ups need to be treated with as much care as the preparation. A single meeting is not an end unto itself; it is a stepping-stone in the much longer path of creating something valuable for the world. In the last few minutes of a meeting, get into the habit of asking, “So before we break, let’s make sure we agree on next steps . . .” After the meeting, send out a recap to the attendees with a summary of the discussion, a list of specific action items and who is responsible for each, and when the next check-in will be.

If a decision was made, then that should be communicated to the right people. If feedback was given, then that should be acted upon. If ideas were generated, then the meeting organizer should clarify what the process is to take those to the next stage. These follow-ups can then anchor the agenda for when the group reconvenes.

Subtraction Tools

Means for Spotting and Removing Destructive Organizational Friction

• Simple subtraction rules. Building on Don Sull and Kathy Eisenhardt’s Simple Rules, these are simple shortcuts and crisp constraints that help people focus their attention on what ought to be removed from their organizations.

• Subtraction rituals. These are scripted actions that people take to mark routine or rare changes when they remove or lose people, places, and practices that have been part of their work lives. These choreographed packages of words and deeds can be simple or elaborate, are imbued with meaning for the people who practice them, and can provide comfort, guidance, and stronger social bonds.

• Subtraction specialists. People or teams charged with keeping life as simple, easy, delightful, and cheap as possible in the organization and have the authority, skill, time, and money to subtract (or add) as they fit.

• Subtraction games. Exercises in which people begin with solo brainstorming about organizational obstacles that slow their work and drive them crazy. Then they meet to share “subtraction targets,” select one or a few to remove, and outline implementation plans. Subtraction games can be as short as thirty minutes or extend for months when people are determined to remove destructive friction.

• Meeting repair and removal tools. These are methods to help people identify and eliminate bad meetings. For meetings that remain, these methods help people make them shorter and less frequent, with fewer attendees, and give people permission to decline invitations and leave meetings that are a poor use of their time.

• Purges. Deep, focused, rapid, and sometimes downright authoritarian efforts to remove an organization’s broken parts.

• Subtraction movements. These are enduring, participative, and multipronged efforts to spread the subtraction mindset throughout an organization, to teach people and reward them for making systemwide and local changes that, taken together, eliminate unnecessary burdens inflicted on employees, customers, partners, and community members.

P.S. Celebrate people who don’t add unnecessary stuff in the first place. Don’t forget those precious people who abhor and resist adding needless stuff, which averts the need for subtraction.

Some organizations fight back with strategic subtraction. Like the monthlong Meeting Doomsday pilot program that Rebecca Hinds at Asana ran with that small group of marketing employees. As we explained above under “Good Riddance Reviews,” the first stage was a meeting audit, where employees studied their calendars and identified recurring meetings that lacked value. The second stage was the Meeting Doomsday part, in which employees removed all of the standing meetings with less than five people from their calendars for forty-eight hours. Then, as Rebecca put it, after people lived “with their newly cleansed calendars” for a couple days, they repopulated them “only with those meetings that are valuable—according to their own meeting audit.” Employees eliminated some meetings, reduced the frequency of others, and made many shorter—cutting thirty-minute meetings to fifteen minutes, and sixty-minute meetings to forty-five minutes. Meeting Doomsday packed a wallop. Rebecca reports participants saved an average of eleven hours per month. One Asana employee, Francesca, in the marketing group, believed her calendar was already in “top shape” before participating in the pilot. But she turned out to be the Doomsday “all-star,” saving thirty-two hours a month.

A piece for Harvard Business Review, “Meeting Overload Is a Fixable Problem,” provided a “playbook” for “meeting resets” that we helped develop and test.
