How to crew an event: which roles you need, and how many
Crewing is a question about positions, not headcount. Which roles a live event actually needs, how the number scales with rooms and hours, when to call each position, and the crewing mistakes that show up at 15:40 rather than at 09:00.
The short answer
Crew an event by counting the positions the show cannot run without, then adding the ones that let those positions take a break. A single-room conference with a stage, screens and radio mics needs a show caller, a sound engineer, a vision or screens operator, a stage manager and a front-of-house lead. Every additional room needs its own version of that list. Every hour past a normal shift needs a relief.
That is a floor, not a recommendation. What sits on top of it is decided by how many rooms run at once, how many outputs the content has to reach, and how long the day is — which is the order the rest of this guide works through.
Which roles do you need?
Think in positions rather than people. A position is a job somebody has to be doing at a given minute; one person can hold two positions in a quiet room and cannot hold two positions during a changeover.
- Show caller
- Calls the cues and owns the running order during the show. One position, one person, and nobody else moves the show. On a small event this is often the producer — it should still be named as a position, out loud, before doors.
- Stage manager
- Owns everything from the wings inwards: speakers in the right place at the right minute, changeovers, furniture, water. The difference between a four-minute changeover and a ninety-second one is almost always this position.
- Sound
- A1 mixes. A2 handles radio mics, packs and batteries and walks the room for dropouts. One person covers both in a room with two microphones. Nobody covers both in a room with eight.
- Lighting
- Runs the states and the changes. On a conference with one fixed look this can be an operator with a plot rather than a designer. On anything with a moment in it, it cannot.
- Vision or screens
- Cuts cameras, rolls VT, drives what is on the screen. Where an event has both a room screen and a stream, that is two jobs even when it is one desk.
- Graphics
- Lower thirds, name supers, holding slides. A separate position because it is a separate kind of attention: getting a name and a job title right while somebody else watches the clock.
Which roles get forgotten?
These are the ones cut first from a budget and missed first on the day. None of them is glamorous and all of them are load-bearing.
- Camera operators
- One per camera unless it is locked off. Count the cameras you have promised, not the ones you hope to get away with.
- Front of house
- Doors, wayfinding, breaks, and the queue that is about to make the afternoon start late. Not a technical role, usually the first one cut, and the one whose absence the audience feels most directly.
- Speaker liaison
- Meets speakers, walks them to the holding area, gets them miked and briefed. Past roughly half a dozen speakers a day this stops being something the stage manager can also do.
- A float
- One person on comms with no fixed position, free to move. A crew with no float has no capacity to absorb the unplanned thing, and there is always an unplanned thing.
- Technical lead
- Owns the kit list, the get-in, the power and the supplier relationship. Not a show-day position — a whole-project one, and the reason the show-day positions have anything to operate.
How to work out the number
Count in this order. Counting rooms last is how a crew plan ends up with one person covering two things that happen at the same minute.
Count the rooms
Every room with a microphone in it needs its own show caller, its own sound and its own screens operator for the hours it is live. Two rooms is not one crew doing twice the work. It is two crews, even where the same people cover different hours.
Count the outputs
A room screen, a live stream and a recording are three outputs. They can share a desk and sometimes an operator, but they cannot share attention during a cue. If two of them can fail independently, plan for the day one of them does.
Count the hours, then add the relief
A crew called at 06:30 for a 09:00 start and a 17:30 finish has been on site eleven hours before the de-rig begins. Somebody has to cover the meal breaks. If nobody is rostered to, the breaks get skipped and the mistakes arrive in the last two hours.
Name a float
One person, no fixed position, on comms. The float is the first line cut from a budget and the first thing you miss when a radio mic dies four minutes into a keynote.
Roster positions, not names
Write the roster as show caller, A1, A2, LX, GFX, stage — then fill the names in. A roster written as positions survives a freelancer dropping out on the Sunday. One written as names has to be rebuilt.
Brief them from the running order
Every position should be able to read the same running order you are working from, filtered to their own department. A briefing that is the only place the plan exists is a plan that stops existing at the first change.
When do you call them?
Call times are where crewing budgets go quietly wrong. The show is eight hours. The crew day is not.
Work backwards from doors rather than forwards from the get-in. Doors at 09:15 means the rehearsal finishes at 09:00, which means it starts at 08:45, which means everything technical was working at 08:30, which means the line check began at 08:00 and the crew were on comms at 07:30. Each of those is a decision somebody has to make. If you do not make them, the crew will make them for you, and they will not all make the same one.
The other end matters as much. The de-rig is a crewed period with a real duration, and it is the one most often left off the roster entirely — which is how three people end up carrying a set that needs six, at the hour of the day when nobody should be lifting anything.
Rehearsal is a crewed session too. It needs the same positions as the show, and it needs to be on the running order with a duration on it, or it will be the first thing compressed when the morning slips.
Where crewing goes wrong
The failures are boringly consistent, and almost none of them are about skill.
One person on two rooms. It works until both rooms need something in the same minute — which is exactly when the programme is running to time, because the rooms were scheduled in parallel on purpose.
No float, so the first unplanned thing consumes a position that was already doing something. A dead radio mic in a keynote pulls the A2 out of the room, and the A2 was also the person who was going to swap the panel mics in the changeover that starts in six minutes.
Freelancers briefed once, from a document. A crew briefed on Tuesday from a running order that changed on Wednesday is working from Tuesday, confidently. The fix is not a better briefing. It is a running order they can read on the day, filtered to their own department.
And the quiet one: nobody rostered for the half hour after the last session, when the client wants to talk, three speakers want their slides back and the venue wants the room.
How EventBlok approaches this
Crewing is a judgement and no software makes it for you. What software can do is make sure every position is reading the same running order.
In EventBlok the showflow carries a department on every cue, and department views for GFX, LX, A/V, FOH and stage are filters on one shared document rather than printed variants. One position moves the show and the others annotate, which is how it works on comms anyway. Every view prints with its version and timestamp on it, because venue wifi is what it is.
Rooms are modelled as real places with an owner and a capacity in multi-location, and turnarounds carry the time the change actually takes rather than being implied by the gap between two sessions — which is the number a crewing plan is built on.
The related reading is what is a showflow and how to write a run of show.
Common questions
How many crew do I need for a conference?
For one room with a stage, screens and radio mics, five positions is the practical floor: show caller, stage manager, sound, lighting, and vision or screens. Add graphics as soon as names go on screen, add an operator per camera that is not locked off, and add a float as soon as the day runs past a single shift. Every additional room repeats the list.
What does a show caller do?
The show caller calls every cue in the running order over comms and owns that running order during the show. One position, one person. Everyone else raises changes rather than making them, which is what stops two versions of the day running at the same time.
What is the difference between a stage manager and a show caller?
The show caller works from the running order and calls the cues, usually from the control position. The stage manager works from the wings and makes the physical things happen: speakers in place, changeovers, furniture, walk-ons. On a small event one person does both. On anything with a changeover under two minutes, they should not.
When should event crew be called?
Work backwards from doors rather than forwards from the get-in. Fix the time everything technical has to be working, then the rehearsal, the line check and the comms check before it. Roster the de-rig as a crewed period with a real duration — it is the one most often left off the roster entirely.
Do I need a separate graphics operator?
As soon as names go on screen, yes. Getting a name and a job title right is a different kind of attention from watching timing, and the two compete at precisely the moment they both matter — the first ten seconds of a speaker walking on.
Can one person run two rooms?
Only if the rooms never need anything in the same minute, and parallel breakouts are designed so that they do. If two rooms run at once, roster two crews, even where some of the same people cover different hours of the day.
Plan the event. Publish the programme. Run the show.
One event spine, many views. Build the programme once, then give every person the right live view of it.
