ESVP
If half the room voted Prisoner, the retro you planned is the wrong meeting. Run a different one.
From Norman Kerth's *Project Retrospectives* (Dorset House, 2001). Anonymous vote at the top of the retro: are you here as an Explorer (curious, ready to dig in), Shopper (looking for one useful idea), Vacationer (glad to be away from real work) or Prisoner (forced)? The histogram is a decision input, not a ritual.
When to use
Top of any retro you suspect the team isn't fully bought into. New cadence, post-incident review, the first retro after a manager change — anywhere the room's mood will shape what's possible. Skip it for a healthy weekly cadence; running ESVP every sprint trains the team to vote Explorer regardless and the signal goes flat.
How it runs
Explain the four labels
Explorer: curious, ready to dig in. Shopper: scanning for one useful idea. Vacationer: glad to be out of real work. Prisoner: here because told to. Read them flat — don't editorialise about which one is 'right.'
Anonymous vote
Each person picks one. Use a poll, a private chat, sticky notes face-down — anything that hides the votes from each other. If the vote isn't anonymous, you'll get four Explorers. That's not a reading.
Reveal the histogram, not the names
Show the count by category. Don't reveal who voted what — the safety of the anonymity is the only reason the data exists.
Decide what to do with it
This is the step the canonical version skips. Three Prisoners and a Vacationer? The retro you planned is the wrong meeting — pivot the agenda, shorten the call, or ask the room directly what's going on. ESVP is a barometer; act on the reading.
Why it works
The four labels do most of the work. 'How are you feeling about this retro?' produces 'fine.' Forcing a choice between Explorer and Prisoner produces an honest answer because the words give people permission to say something they wouldn't otherwise. The histogram then gives the facilitator a decision input ten minutes before the meeting would have surfaced the same problem the hard way.
Variations
- Three-label version: drop Shopper. Useful for shorter check-ins where the four-label distinction is too fine.
- Weather check-in: same shape (sunny, cloudy, stormy, foggy) — softer for teams that find ESVP too jargony.
- Five-point energy scale: 1-5 vote on energy level. Less diagnostic but works for short stand-ups.
Facilitator notes
Vote yourself, last. Show the histogram before you start the agenda. If three of eight are Prisoners, name it directly: 'Half this room doesn't want to be here. Tell me what would make this useful, or we'll cut the meeting to twenty minutes.' That conversation is the actual retro on a Prisoner-heavy day.
Pitfalls
- Voting publicly. You'll get all Explorers. The anonymity is the format.
- Showing the histogram and moving on. The act of looking at it is half the point — pause for ten seconds.
- Taking a Prisoner-heavy result personally. It's data, not a verdict. Treat it like one.
- Running it weekly until people vote Explorer reflexively. Use it when you suspect the answer matters.
Remote tips
Anonymous Slack poll, Miro hidden voting, or a private DM to the facilitator — all work. A quick poll bot is faster than a sticky-note board. The reveal is the histogram alone; do not show individual votes even by accident.
Example outputs
- Histogram on a healthy team: 5 Explorers, 2 Shoppers, 0 Vacationers, 0 Prisoners. Run the retro you planned.
- Histogram after an incident: 1 Explorer, 1 Shopper, 3 Vacationers, 3 Prisoners. The team is exhausted; pivot to a 20-minute check-in or reschedule.
- Histogram on a flat team: 8 Explorers. That's not a real reading; you skipped the anonymity.
FAQ
- ESVP or Plus/Delta?
- ESVP is a check-in — top of the meeting, asks 'are we ready for this?' Plus/Delta is a check-out — end of the meeting, asks 'how did it go?' Different jobs, different positions in the agenda.
- Should I share the histogram with the team?
- Yes — that's most of the value. The facilitator-only version is a comfort blanket; the team-visible histogram is what gives the meeting a chance to recalibrate.
- What if the team always votes Explorer?
- Either you have a unicorn team, or the vote isn't actually anonymous. Check the second possibility first.
