What is a quorum?

Quorum: A quorum is the minimum number of members who must take part, by attending a meeting or by voting, for a group's decision to count. Under Robert's Rules of Order, the default is a majority of the entire membership unless the group's own rules set another number.

A quorum stops three people deciding something for thirty. Boards, committees, clubs and community groups usually define one in their bylaws. Teams voting in Slack rarely do, until a decision made by a handful of people gets challenged.

Example polls

Paste any of these into the message box in Slack.

/poll "Adopt the new on-call rotation from next month? Counts if at least 6 of the 9 leads vote." "Yes" "No" "Abstain" limit 1 close after 2 days remind 3 hours before closing

Choice poll. A committee vote with the quorum written into the question.

What it means in practice

A quorum is about turnout, not the result. If a 9-person committee has a quorum of 5, a vote with 4 participants decides nothing, however lopsided. Once the quorum is met, the normal rule (majority, two-thirds) decides the outcome among those who voted.

Under Robert's Rules, a group without a quorum can't transact business: it can only adjourn, recess, fix a time to adjourn to, or try to get a quorum. Your team doesn't need to be that formal, but it helps to decide the number before the vote, not after.

Applying a quorum to a Slack vote

Simple Poll doesn't have a quorum setting. A poll closes whether 2 people voted or 200. You apply the rule yourself:

  1. Say it in the question: "Counts if at least 6 of the 9 leads vote."
  2. Give it a deadline with close after (Premium), so everyone knows when the count is taken.
  3. Remind people with remind 3 hours before closing (Premium).
  4. Include "Abstain" so people who want to be counted without taking a side can be.
  5. Count voters, not votes. With limit 1 (Premium) each person casts one vote, so the total is the number of voters.

If the quorum isn't met, say so and decide what happens next: extend, re-run, or hand the decision to the owner.

Questions

Does an abstention count towards a quorum?

In meeting procedure, a member who is present counts towards the quorum whether or not they vote. In a poll, an "Abstain" option is how someone shows up without voting yes or no.

Can Simple Poll block a result if turnout is too low?

No. It has no quorum setting. State the rule in the poll and check the count when it closes.
