A group-decision packet with scope, input rounds, eligibility and scores, vote record, concern-based revision, and follow-through log.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • State decision authority, limits, and a neutral question.
  • Provide a participation round with a written-input option.
  • Apply mandatory screens and preference scores consistently.
  • Record both ballots, the concern, and the location revision.
  • Create a task log and a trigger for reconsidering the choice.

Review and revise

Use these criteria to check your work and choose what to improve.

  • All four members have a usable input route.
  • Eligibility and score arithmetic match supplied facts.
  • The vote threshold and tie process are applied correctly.
  • The final record preserves dissent and assigns follow-through.

The idea in everyday life

Fictional club chooses simple majority among eligible options, one vote per member, at least 3 of 4 votes required to win. Tie rule: discuss the top tied options, then revote once; if still tied, record no decision and seek another option. First ballot: games Jo/Ren; puzzle Alex/Kim. This is not a consensus process.

The idea

The rule should be agreed before participants know who will win.

Follow along

Choose and rehearse a decision rule: guided practice

The rule should be agreed before participants know who will win.

Use paper or a free local text editor. This is an original fictional practice case; do not submit its records to a real service. Start this lesson with these facts, even if an earlier variation changed them. Fictional club chooses simple majority among eligible options, one vote per member, at least 3 of 4 votes required to win. Tie rule: discuss the top tied options, then revote once; if still tied, record no decision and seek another option. First ballot: games Jo/Ren; puzzle Alex/Kim. This is not a consensus process.

  1. 1. Record the threshold

    Write what counts as a winning majority.

    You should see: At least 3 of 4 votes.

    Half of four is not a majority.

  2. 2. Count the ballot

    Tally each option.

    You should see: Games 2; puzzle 2; neither wins.

    The tally must follow the rule rather than the facilitator’s preference.

  3. 3. Apply the tie process

    Use a supplied second ballot: games Jo; puzzle Ren/Alex/Kim.

    You should see: Puzzle wins the revote with 3 votes.

    The agreed tie procedure determines the next valid step.

  4. 4. Distinguish agreement

    Record the result without calling it unanimous or consensus.

    You should see: Majority decision for puzzle; Jo preferred games.

    Different decision rules mean different levels of agreement.

Now change one thing

Changed case: a five-member group requires more than half to win. Enter the minimum winning vote count.

Your work

What to finish

Choose and rehearse a decision rule record with the worked decisions and changed-case check.

Common mistake

Watch for this

Calling a majority result consensus or changing the tie rule after the vote.

How can I tell I understand it?

Apply a stated voting or consent rule and handle ties consistently. Explain the evidence behind the result and correct any mismatch.
