How to plan stage changeovers for a multi-act music event

You've booked the bands, agreed their set lengths and fitted everyone before the venue's finish time. Then the production team asks how one band's equipment gets off the stage while the next band's equipment gets on. You still need time to clear equipment, prepare the next act and check that everything works.

Plan stage changeovers around the actual difference between consecutive acts. Agree what stays, what moves, who moves it and which checks must finish before the next performance starts. Only then should you confirm the gaps between sets. Giving every band the same changeover time is convenient, but it doesn't tell you whether the work fits.

For a paid music event, the consequence reaches beyond a late start. A rushed change can interrupt the performance people bought tickets to see, push later artists towards a hard finish or add costs you haven't authorised. You need a schedule that the artists, stage crew and technical leads have actually accepted.

This guide explains how to build that schedule, with a fictional four-act evening and a changeover sheet you can copy. All example times are planning assumptions, not standard durations or instructions for specialist work. Your production team must confirm the methods, staffing and time your event needs.

Start with the limits on the whole evening

Before deciding whether a band needs a short or long changeover, establish when live music can start and must finish. Check the venue agreement, applicable permissions, noise conditions and artist contracts with the people responsible. Also distinguish the end of amplified music from audience departure and the deadline for returning the building.

A venue might allow people to remain after the last song while requiring the performance to stop earlier. A supplier might have priced technicians only until a particular time. Those are different restrictions, and an apparently available half hour doesn't resolve either one. Write down the actual constraint and who can authorise a change.

Next, list the performance promises you've made. Include agreed set lengths, any fixed appearance time, special guest moments and production elements the artist has accepted. If you're considering shorter sets to make the evening fit, settle that before publishing the timetable. A working draft doesn't amend an artist agreement.

Your event production brief should already identify the equipment and services you're buying. The changeover plan adds the movement between acts. Keep it connected to the wider production schedule so an afternoon rehearsal, equipment delivery or crew break isn't assumed to happen in time that another activity already occupies.

Have one production contact collect the constraints and circulate the accepted version. Artist representatives need the parts affecting their performances; the venue and suppliers need the parts affecting their work. Resolve disagreements while you can still change bookings, rather than asking the stage manager to settle them as the audience waits.

Find out what each act is really bringing

The first thing you want from each act is its current technical rider, stage plot and input list. The rider describes requirements, the stage plot shows where performers and equipment go, and the input list identifies the sound sources the audio team must connect. Ask who can approve changes on the artist's behalf.

Don't treat an attachment as a confirmed agreement. A touring rider might describe the act's preferred production at a much larger venue, or show musicians who aren't appearing on this date. Have your technical lead discuss the actual performance and send back an agreed version. Record unresolved items with an owner and a deadline.

Ask specifically about equipment arriving with the band. Instruments are only part of that conversation. Pedalboards, computers, playback devices, personal monitor systems and an artist's own mixing desk can all change the handover. A seemingly simple act can need a complicated connection to the house system.

Confirm who supplies each item and who operates it. "Band brings drums" could mean a complete kit, or only the drummer's personal pieces. Ask about stands, cables, cases and any accessories needed for the agreed setup. Missing small items can stop a changeover just as effectively as a missing amplifier.

Make arrival and preparation requirements part of the confirmation. An artist arriving at the venue shortly before the set may still need unloading, accreditation, an equipment check and time to reach the preparation area. Work backwards from when the equipment must be ready, not only from when the artist is advertised to appear.

Use the artist liaison checklist for arrivals, contacts and performer support. The liaison person should help resolve missing information and locate people. They shouldn't have to guess whether a substitute amplifier is technically suitable or whether a change fits the audio plan.

Agree shared backline item by item

Backline means the instruments and associated equipment used on stage, such as drums, amplifiers and keyboards. Sharing some of it can reduce what moves between acts, but the saving depends on what the artists actually agree to use. "Shared backline provided" is too vague to base a timetable on.

Start with a clear inventory showing the exact proposed items. Ask each artist to accept the relevant equipment or explain the required alternative. Record that response against the item. A drummer accepting the house drum shells hasn't necessarily accepted its cymbals, pedal, seat or the position of every stand.

Also agree what can be adjusted and who restores it. If the next drummer changes the setup, the following act may need another reset. A shared keyboard stand can save a movement while creating a height adjustment. Your changeover duration needs to include those actions rather than counting only equipment carried across the stage.

Decide how personal equipment stays identifiable. Label artist-owned items through an agreed, non-damaging method, and designate a representative to receive them after the set. Separate them from hired and venue equipment in the recovery area. The crew needs a clear answer when two similar cases appear at the same exit.

Sharing has limits. An artist may need a particular instrument, an unfamiliar substitute may undermine the performance, or a shared item may become a single point of failure. Ask the supplier for a suitable backup arrangement and explain what happens if the shared item becomes unusable. Don't solve the timetable by imposing a substitution nobody has approved.

Once the inventory is accepted, make it easy to tell what stays in position, what changes and who owns each action. Keep commercial agreements about equipment damage and responsibility with the appropriate booking records. Stage crew need the practical instruction, not an invitation to negotiate ownership while moving equipment.

Plan every transition as its own job

Read the stage plots in programme order. Compare the first act with the second, the second with the third, and so on. For each pair, list what remains, what leaves, what enters and what gets adjusted. This is more useful than giving each act a setup duration without considering the stage it inherits.

A solo performer followed by a full band may involve more incoming equipment than the reverse transition. A band using the same drum shells might still need a different keyboard position and monitor arrangement. Ask the crew to describe the actual sequence, including actions that must wait for someone else to finish.

Begin with permission to start the change. The outgoing performance must be finished, the relevant audio handoff agreed and the stage released for the planned movement. Define how the stage manager receives that confirmation. A musician's final wave doesn't necessarily mean every part of the outgoing setup is ready to disconnect.

Then follow outgoing equipment to its destination. Where does it wait? Who receives personal instruments? Can empty cases return without obstructing incoming equipment? A plan that stops at "clear stage" can leave the wing full of gear that blocks the next changeover.

For incoming equipment, follow the route all the way to its marked position. Include connections, adjustment, checks and the final readiness decision. Ask each department to identify the condition it needs before beginning. That exposes hidden waits, such as an audio technician needing a riser in position before connecting its equipment.

The Health and Safety Executive's event management guidance, relevant to Great Britain, calls for coordinated work, competent staff and a phased programme that accounts for contractors' risk assessments. Apply the appropriate requirements for your location. The organiser coordinates the overall sequence while specialists remain responsible for their work.

Check the stage wings and movement routes

A large stage doesn't guarantee a quick changeover. The limiting space may be beside it, where incoming equipment needs preparing and outgoing equipment needs parking. Review those spaces with the venue and production leads before accepting a plan that relies on several setups waiting nearby.

Mark the preparation area, outgoing equipment area and storage for empty cases. Identify the access route for performers, including anyone who needs an accessible route or assistance. Keep emergency and working routes available under the approved site arrangements. Nobody should discover that the proposed keyboard holding position occupies an exit.

Agree stage directions and name the zones consistently. Stage left and stage right are usually described from the performer's view towards the audience; confirm that convention during the briefing and put it on the drawing. "Over there" becomes particularly unhelpful when someone is calling a movement from the opposite side.

Ask the crew to check the actual equipment through the route. A riser that fits on stage might not fit through its approach with equipment assembled on it. A ramp may have restrictions that change how the supplier proposes to move a load. Those questions belong with the competent people planning the movement, before its duration is accepted.

Preparing equipment while another act performs can help, provided the activity, space and people are suitable. It mustn't disturb that performance or require moving through an occupied working area without permission. An assembly that can't safely travel in its prepared state offers much less benefit than the timetable suggests.

If you're still deciding the performance area's dimensions, use the guide to choosing an event stage size. Then confirm the changeover arrangement against the actual approved layout. Extra floor area isn't automatically saleable audience space, and wing space isn't spare space once the production depends on it.

Make the audio handover specific

Ask the audio lead to own the connection plan across the whole bill. It should show how each act's sound sources reach the mixing system, what remains connected and what changes. The patch is the agreed mapping between each sound source and its input on the audio system. Label connections consistently so the crew can follow that mapping.

Confirm how guest engineers will use the house equipment. If they bring saved console settings, the audio supplier must check suitability for the actual console, software and system configuration. A saved setup doesn't prove that physical connections, monitor feeds or protected house settings are correct. Agree how settings will be loaded and selected before the live change.

Separate a line check from a soundcheck in the artist confirmation. A line check verifies the agreed connected sources and essential signal paths. A soundcheck gives the act and engineers time to work on the performance sound and monitoring. Don't promise a full soundcheck in a slot the team has allowed only for connections and essential checks.

Book any required pre-show soundchecks separately, with the artists and engineers needed to complete them. Confirm when their equipment can be installed, tested and left ready, and what changes after another act uses the stage. Ask which checks must be repeated after shared equipment has been moved or adjusted.

If an act will receive only a line check before its performance, make that explicit during the technical discussion. Ask its representative and the audio lead whether the arrangement supports the agreed show. Any additional rehearsal or check needs a confirmed place in the schedule, with access and crew coverage. It cannot remain an informal promise to find time before doors.

Wireless microphones and in-ear monitors also need advance coordination. In its 2017 account of the iHeartCountry Festival, Shure describes contacting artists about their wireless equipment and planning frequencies before onsite confirmation. It's a documented example of preparation, not a claim that the same arrangement suits your event.

Have the responsible audio specialist collect the required wireless details, approve the operating plan and control late additions. A performer testing an uncoordinated transmitter backstage can affect systems already in use. Make check-in instructions clear so artists know who to speak to before operating their equipment.

Finally, name the person who confirms audio readiness and the route for reporting a fault. The stage manager needs a usable answer, such as which required source hasn't passed its check and the next forecast. "Audio nearly there" doesn't establish whether the artist can perform or what decision the organiser faces.

Keep lighting and other departments in the handover

Audio and backline may do most of the visible work, but check what other departments need during the same interval. Lighting staff may need to confirm the incoming look, a video operator may need approved content, and a recording team may need the correct act identified. Ask each lead which actions require stage access and which happen at a control position.

Agree who authorises the lighting state used while equipment moves. The audience can understand that a changeover is happening without the crew being asked to work in unsuitable darkness. A dramatic entrance cue comes after the required readiness confirmations, under the accepted operating procedure. It should not force an incomplete transition to continue out of sight.

Keep sponsor appearances, host introductions and presentation moments in the same live sequence. If a sponsor representative needs the performance area while the crew is moving equipment, that is a scheduling conflict to resolve. Move the appearance to an agreed place or time rather than assuming the crew can work around an unbriefed visitor.

For any specialist effect or moving production element, ask its responsible supplier what the transition requires and whether the existing plan allows it. The example below excludes those elements. Adding one means reviewing the relevant methods, approvals, work areas and timing before confirming the revised programme.

Estimate the changeover with the people doing it

There isn't one correct festival stage changeover duration. The time depends on the difference between the acts, available preparation space, movement routes, staffing and required checks. Ask the relevant leads for estimates against those conditions, then test the sequence wherever practical.

Break the work into actions with owners and dependencies. Some actions can happen together; others cannot. Don't add every department's estimate if work genuinely overlaps, but don't count an overlap simply because two tasks appear on the same row. The leads must confirm that the necessary people and space are available simultaneously.

A stagehand assigned to remove outgoing guitar equipment cannot also be moving an incoming keyboard at the same moment. The audio technician checking a connection may need the backline technician beside them. Read the sequence by person as well as by clock time. Staffing assumptions often explain why an attractive estimate doesn't survive rehearsal.

Ask what each estimate includes. Does it start with the last note or with the stage already clear? Does it include the artist reaching the stage and making essential adjustments? Does it end with equipment placed or with the performance ready to begin? Get everyone estimating the same interval.

Include an explicit allowance for small corrections after the planned work. Base it on the particular uncertainty and what your team has observed, rather than adopting a universal percentage. That allowance doesn't authorise unsafe work, replace a missing specialist or extend a venue restriction. It only provides time within the accepted arrangement.

When the estimate still exceeds the available gap, change something real. You can discuss simpler equipment requirements, different preparation arrangements, more suitable staffing or revised programme times. If none works, the programme doesn't fit. Required checks should keep their time while the booking decisions are reconsidered.

A worked schedule for a four-act evening

Consider a fictional paid music night on one stage. The production and artist representatives have accepted the required setups, set lengths and transition estimates. Music must finish by 21:30 under this example's agreed arrangements. Audience departure and equipment removal have separate plans after the programme.

The planned performances are:

• Act A plays from 17:00 to 17:35, followed by a 20-minute changeover.

• Act B plays from 17:55 to 18:35, followed by a 25-minute changeover.

• Act C plays from 19:00 to 19:50, followed by a 30-minute changeover.

• Act D plays from 20:20 to 21:20, leaving 10 minutes before the music finish limit.

Those gaps differ because the transitions differ. The first uses a relatively similar accepted setup. The second adds a keyboard arrangement and changes personal drum items. The final transition has more outgoing and incoming equipment. These descriptions explain the fictional choices; they aren't estimates you can transfer to your own bill.

The production team has confirmed a preparation area and booked the relevant crew through the full programme. Artist arrivals allow agreed checks before equipment enters the live sequence. No special effects or structural changes are included. If the actual event adds either, it needs the relevant specialist planning and revised timing.

The last 10 minutes aren't an extra encore entitlement. They are remaining time before a fixed constraint, and using them may affect other arrangements. The organiser must still check artist agreements, staffing and audience communication before approving a later performance finish.

The broad setup and removal windows belong in the event production schedule. Put the set times, transition references and live cues in the run of show. Each transition sheet can then carry the detail needed to move between those published performances without making the audience timetable unreadable.

Build the second changeover minute by minute

For the transition from Act B to Act C, the fictional crew has accepted 22 minutes of sequential work, followed by three minutes of recovery allowance. The sequence below is deliberately sequential so you can see where the time goes. A real team may agree different durations or safe overlaps.

At 18:35, Act B's set ends. The stage manager coordinates the agreed release and audio handover. That takes two minutes in this example, finishing at 18:37. Only then does the planned outgoing equipment movement start.

Between 18:37 and 18:42, the assigned crew removes Act B's personal items and transfers them to the designated receiving area. The shared equipment remains as agreed. The receiving person accounts for the items without filling the incoming route with open cases.

Between 18:42 and 18:48, the crew places Act C's prepared keyboard setup and personal drum items, completes the agreed adjustments and confirms positions. This six-minute block assumes the preparation work has already finished and the approved movement route is clear.

Between 18:48 and 18:51, the responsible technicians complete the planned connections. Between 18:51 and 18:56, audio carries out the agreed line and monitor checks with the required performers available. A problem receives a named owner and a forecast; the team doesn't mark an untested source as complete.

At 18:56, the stage manager collects the required readiness confirmations and coordinates the artist's start arrangements. That final minute takes the sequence to 18:57. The remaining three minutes before 19:00 are the stated recovery allowance, available only within the accepted conditions.

The calculation is two minutes for release, five for removal, six for placement and adjustment, three for connections, five for checks and one for final readiness. That totals 22 minutes. Adding the three-minute allowance gives the 25-minute gap. None of these durations is a recommended minimum or a supplier benchmark.

Copy this stage changeover sheet

Create one sheet for each transition and give it a stable reference, such as C02 for the second changeover. Keep it short enough for the stage manager and department leads to use during the show. Detailed equipment inventories and specialist instructions can be attached, with their current versions clearly identified.

Start with the header:

• Event, date and stage: [name, calendar date and exact stage].

• Transition reference: [outgoing act to incoming act, with a unique reference].

• Document version: [issue time, owner and status].

• Planned interval: [outgoing set end, incoming start and agreed changeover duration].

• Fixed restrictions: [music finish limit, access restrictions and relevant noise conditions].

• Responsible contacts: [stage manager, department leads and artist representatives].

Then record the movement and checks:

• Stays in position: [accepted equipment and anything that must not be changed].

• Outgoing equipment: [item, owner, assigned crew and receiving location].

• Incoming equipment: [item, preparation status, assigned crew and final position].

• Routes and work areas: [agreed movement order, controlled crossings and holding areas].

• Technical handover: [current patch reference, monitoring arrangement and relevant playback or wireless instructions].

• Readiness requirements: [department confirmations, required artist presence and person authorising the start].

• Fallback: [approved alternatives, decision owner and conditions that require a hold].

For each timed action, add its planned duration, what must finish first and who reports completion. Keep planned, forecast and actual times distinguishable. If the first movement begins late, the sheet should let the stage manager work out the consequence without erasing what the team originally agreed.

For C02 in our example, the outgoing act is B, the incoming act is C and the planned interval is 18:35 to 19:00. The shared drum shells remain. Act B's agreed personal pieces leave for its receiving area; Act C's accepted personal pieces and keyboard setup enter from the preparation area.

The connection plan references the audio lead's current document. It doesn't ask the stage manager to rewrite that specialist information. The stage manager receives completion reports from backline and audio, confirms the other applicable readiness conditions, then coordinates the performance start. Any hold follows the event's agreed authority and communication procedure.

Keep personal phone numbers and sensitive artist information in the controlled working copy. A supplier needs an available contact and the instructions affecting its work. A public timetable needs set times. Neither requires distributing the complete backstage contact list to everyone who asks for a schedule.

Give the crew clear cues and cover

Name the stage manager and clarify who coordinates the transition. Name the technical leads who can confirm their department is ready, the artist representative who can approve an agreed alternative, and the organiser who can authorise programme or spending changes. Several people can contribute without giving competing instructions to the crew.

Use specific communication rather than a general instruction to hurry. A department should report what is complete, what remains and its forecast. The stage manager can then identify the action holding up the start. Test radios or intercoms in the actual working environment and agree a backup route for essential messages.

Confirm the clock everyone uses. A printed set list, a technician's phone and a wall clock can otherwise show different times. Include dates when the operation crosses midnight. Agree how advance warnings reach the outgoing artist, and who receives the instruction to finish under the accepted performance arrangement.

Brief relief staff as carefully as the opening crew. A replacement technician needs to know the current setup, changes already approved, equipment faults and the next transition. A name on the rota doesn't prove that person has received the latest patch or understands why a particular case must stay out of the incoming route.

HSE's fatigue guidance identifies workload, shift duration, timing and breaks as factors affecting fatigue. Agree suitable calls, breaks and handovers with the relevant employers and follow local requirements. Don't build the evening around the assumption that the same people can keep working whenever the programme slips.

For a small event, one person may hold several coordination duties where that is workable and competent. Check what happens during the busiest transition. The person helping an artist at the gate cannot also be physically present to release the stage. Arrange cover or move the duties before accepting that combination of roles.

Decide what happens when a set runs late

Agree delay decisions before the show. Establish who can propose a revised start, who must approve any change to an artist's set and who confirms the effect on the venue's restrictions. The stage manager needs that authority structure without having to negotiate it over a noisy radio channel.

Use our fictional C02 to see the difference between absorbing a delay and removing necessary work. Suppose Act B ends seven minutes late, at 18:42. If the same accepted 22 minutes of work follow, Act C can be ready at 19:04. The three-minute allowance absorbs part of the delay, leaving a four-minute late start.

That forecast assumes the work proceeds as planned, with no further fault and all required people present. The allowance has now been used. It doesn't justify telling the audience that the start is definitely 19:04 while a required check remains unresolved. Report the current forecast and update it when the evidence changes.

If the organiser approves preserving Act C's full 50-minute set, it finishes at 19:54. Preserving the next 30-minute changeover starts Act D at 20:24. Its full 60-minute set then finishes at 21:24, six minutes before the example's 21:30 limit. That is one possible revised plan, subject to the relevant agreements and readiness confirmations.

It isn't permission for every later act to run over. Check the remaining time again after each actual finish. Transport, booked staffing, venue services or a fixed artist departure may create a tighter limit than the final music deadline. Put those constraints in the decision instead of looking only at the last row of the programme.

If the revised programme won't fit, discuss approved alternatives while there is still time. Those might include removing an optional production element before it is installed or agreeing a changed set with the artist representative. A technical lead must confirm any changed setup remains workable. Don't reclaim minutes by silently skipping checks or shortening an artist's performance without agreement.

Prepare fallbacks for the failures that would stop a set

Ask each technical lead what is most likely to prevent this particular transition from finishing and what an acceptable alternative would involve. Concentrate on the actual dependencies. A spare cable helps only if it is suitable, accessible and someone knows where it is when the relevant connection fails.

If an incoming item hasn't arrived, the artist representative and supplier need to assess the available alternative. Record the acceptance before the crew changes the plan. An artist may be able to perform with a simpler setup, but that decision needs the people who understand the performance and technical consequences.

A proposed fallback can also affect what you advertised. Removing a visual effect may be an acceptable production adjustment in one event and a material loss in another. The organiser must consider the ticket promise and appropriate attendee response. Don't let the backstage team make commercial promises or decide remedies beyond its authority.

Be particularly clear about power. HSE's event electrical safety guidance includes planning power requirements, controlling access to electrical installations and arranging cables for safe installation and removal. Have the competent electrical and technical leads agree relevant procedures. A short changeover is no reason for an unqualified person to improvise a connection or bypass protection.

For outdoor events, weather decisions belong to the approved safety and specialist operating arrangements. A wet preparation area or unusable movement route changes the conditions behind the estimate. The stage manager needs to know who reassesses the affected work and what must be confirmed before it resumes.

Preserve the emergency communication arrangements throughout. A technical fault, a late artist and an emergency are different situations. Staff should know how an urgent safety instruction takes priority and who controls the response. An entertainment announcement mustn't distract from a message that the event's emergency procedures require people to hear.

Plan what the audience experiences between acts

The gap between sets is part of the paid experience even when no act is performing. Decide who controls permitted background music, house lighting, screen information and announcements. Give them the accepted cues, and make sure backstage work doesn't depend on an announcement operator guessing when a check has finished.

Don't fill every available moment with loud playback. The audio team may need a quiet interval to identify a problem or communicate with performers. Crew and audience exposure also matters. HSE's event noise guidance addresses both worker and audience exposure and distinguishes noise nuisance responsibilities. Agree suitable arrangements with the competent people responsible for your event and location.

If you use a host, write useful holding information and a clear instruction about when to stop speaking. The host needs a confirmed update, not an invitation to promise that an act will appear in a minute. Avoid naming a band member as the cause of a delay when the production team is still establishing what happened.

Tell front-of-house staff when a revision changes what attendees need to know. They need a consistent answer for people asking whether they've missed an act, whether re-entry is available under the event's rules or when a changed performance is expected. Keep accessible information channels in the plan alongside spoken announcements.

For a timetable change agreed before the event, Loopyah's attendee email tools let you send an event update to ticket holders. Write the confirmed change and its practical effect clearly. During the show, use the onsite channels your event has prepared; email alone isn't a dependable way to reach someone waiting near the stage.

Keep the published timetable aligned with approved decisions. If a start remains a forecast, label it accordingly through the communication format you're using. An old screen graphic and a newer announcement can leave attendees following different instructions. Name the person who updates the relevant channels and confirms the change has appeared.

Check the cost before adding equipment or people

A faster transition may need another item of hired equipment, more preparation space or additional crew. Ask which specific task the proposed change shortens and whether the rest of the sequence benefits. Paying for a second keyboard stand won't help if the only route remains occupied by outgoing equipment.

Request a comparison against the accepted plan. Include preparation, delivery, staffing, any extra venue time and removal. An item that appears inexpensive to hire may require additional transport or handling. Make the decision using the complete agreed charge, rather than a headline daily rate.

Check whether extra preparation would avoid buying duplicate equipment. Conversely, don't force a shared setup that artists haven't accepted simply because it looks cheaper. The useful saving is one you can achieve while delivering the agreed performance. A later dispute, emergency hire or compromised set can undo the apparent advantage.

Record who can approve additional spending during the event and how the supplier receives that approval. The stage manager should be able to escalate a costed option without being expected to negotiate rates mid-changeover. A safety hold must remain available regardless of whether a commercial decision is still pending.

After the show, compare extra charges with the approvals and actual work. If a delay involved several causes, record them separately. Artist lateness, a missing supplied item and a blocked venue route call for different changes next time. An unexplained total labelled overtime won't help you build a better schedule.

Test the difficult transitions before issuing the final times

Walk through the most demanding change with the department leads, using the actual layout and equipment wherever practical. Confirm the outgoing destination, preparation area, assigned people and order of movement. Include the artist's essential adjustment time and required checks. Time a complete accepted sequence rather than a convenient fragment of it.

The test may reveal that your first estimate was wrong. Keep that information. If moving an assembled setup takes longer than expected, ask whether preparation or placement can change safely. If the physical route is the constraint, the timetable may need more time. Repeating a faster target doesn't change what the crew just demonstrated.

Before issue, read each sheet with the people delivering and receiving the handoffs. Resolve missing confirmations and mark unresolved requirements honestly. Link the transition references to your event run of show, and confirm that artist representatives and operational leads have the versions affecting them.

During the event, record actual set endings, changeover starts, readiness and performance starts. Note the reason for a hold while people remember it. An unexplained late start tells you far less than knowing that the next act's equipment was ready but its required performer hadn't reached the stage.

Use the review to revise estimates for the next event, then confirm them against its actual bill, venue and crew. Before you publish that next timetable, take the most demanding transition and ask the people doing it to explain how it fits. If an essential action still has no time, owner or available route, keep the timetable provisional until that decision is resolved.
