Common uses for a dot voting timer
- Workshop convergence
- Prioritising a backlog
- Retrospective topic selection
- Narrowing a long option list
Dot voting converges a group on a shortlist by giving each participant a fixed number of dots to distribute across the options. It is fast, visual and requires no discussion, which is why it appears at the end of almost every workshop that generated more ideas than can be pursued.
Three minutes suits a set of ten to twenty options. The time should be enough to read everything and choose deliberately, and short enough that people vote on their reading rather than on a negotiation with the person next to them.
How many dots
A common formula is dots equal to roughly a fifth of the number of options, with a floor of three and a ceiling of about five. Ten options gets three dots; twenty gets four or five.
Too many dots and everything gets votes, which defeats the exercise. Too few and the result is dominated by whichever option happens to be first read. The aim is a distribution with a visible top three, not a flat one.
Vote at the same time, not in sequence
Dot voting has an obvious failure mode: people can see where the dots already are. Once an option has five dots, the sixth voter is choosing under influence, and the result measures herding as much as preference.
Voting simultaneously — everyone at the wall at once — mitigates it, and voting privately then transferring dots removes it entirely. The private version costs two extra minutes and is worth it when the decision matters.
It is a shortlist, not a decision
Dot voting is good at reducing twenty options to three and bad at choosing between those three. Treating the top-voted item as the decision skips the discussion where the actual trade-offs surface.
The standard sequence is dot vote to a shortlist, discuss the shortlist, then decide — with someone named as the decider if the group does not converge.
A workable formula. Aim for a distribution with a visible top three rather than a flat one.
| Options | Dots each | Voting time | Note |
|---|---|---|---|
| 5–8 | 3 | 2 min | Small set |
| 9–15 | 3 | 3 min | The common case |
| 16–25 | 4 | 4 min | — |
| 26–40 | 5 | 5 min | Consider grouping first |
| 40+ | 5 | 6 min | Group into themes before voting |
- Vote simultaneously, or privately then transfer — visible running totals turn the result into a measure of herding.
- Dot voting produces a shortlist, not a decision. Discuss the top three before choosing.
