On-site coordination is the real-time management of the team, suppliers, and running order for the duration of an event — from the first supplier arriving in the morning to the last guest leaving at night. Unlike planning, which happens weeks in advance, coordination is decision-making in real time, where mistakes get corrected on the fly. Good coordination isn't about nothing ever going wrong; it's about guests never noticing the small things that did.
What on-site coordination actually covers
On-site coordination means one person, or a small team, keeps a live picture of what's happening right now, what's coming next, and who owns it. It isn't about doing every task personally — it's about holding the full picture across technical production, catering, programme, and guests at the same time. Without this function, even a well-planned event fractures into isolated pockets: the AV crew handles their piece, catering handles theirs, and the host has no idea the schedule has shifted.
For a small internal gathering, one person from HR or office management often covers this role alone. For a conference with hundreds of guests or a multi-day event, it needs a team with clearly divided zones of responsibility.
Who needs to be physically on site
Team size depends on the scale and format of the event, but a handful of roles show up almost every time. The table below shows a typical breakdown for a mid-sized corporate event.
| Role | Responsibility | |---|---| | Lead coordinator | Overall picture, decisions on any deviation from plan | | Technical coordinator | Sound, lighting, projection, transitions between segments | | Guest coordinator | Registration, guiding guests, VIP communication | | Catering contact | Timing of food service, allergies, replenishment | | Venue contact | Access to spaces, building infrastructure, cleaning |
A smaller event can run comfortably with one or two people combining these roles. For a larger one, splitting them across separate people matters — one person can't handle a technical failure and an unhappy guest at registration at the same time.
How to build a run sheet that actually holds up
A running order for guests is not the same thing as a run sheet for the team. The programme tells the audience what's happening on stage; the run sheet tells every team member what to do, minute by minute, including all the setup guests never see — equipment load-in, supplier arrivals, the host's briefing.
A run sheet that works has three traits: it's shared with everyone who needs it, not just the lead organizer; it builds in slack between critical programme points instead of times accurate to the second; and it's available offline — relying entirely on a mobile connection during the event is a risk in itself.
How the team should communicate during the event
Radios or a group chat with clear rules for who reports what to whom work noticeably better than individual phone calls. For a larger event, it's worth having a dedicated channel for critical updates — a schedule slip, a technical issue — separate from routine operational chatter, so an important message doesn't get buried under dozens of minor ones.
Just as important is a short in-person briefing for the whole team right before the event starts, not an email sent the day before. A team that's walked through the run sheet together reacts to deviations faster than a team that received a document and is trusted to have read it on their own.
Why a technical rehearsal the day before is worth doing
Where the venue and schedule allow it, a technical rehearsal the day before an event surfaces problems that would otherwise only show up in front of guests — incompatible connectors, a weak microphone signal in one corner of the room, a cable that turns out to be shorter than the team brought. A rehearsal on the day itself, right before guests arrive, is always the worse option, since there's minimal time to fix anything and the team is already stretched thin on last-minute prep.
The same logic applies to walking the venue with the full team — registration, main hall, catering, escape routes. Every team member should know where things are before the first guest asks them. A team that moves through the venue with confidence reads as far more professional to guests than one still learning the layout on the fly.
What to do when the schedule starts slipping
A few minutes of drift is a normal part of nearly every event and doesn't call for panic — it calls for a decision about where the time gets made up. An experienced coordinator knows in advance which programme points have slack built in (breaks, transitions between rooms) and which are fixed (buses departing, the end of the venue rental). Time should come out of the slack, not out of the content guests actually showed up for.
If a slip is heading toward a fixed deadline, the lead coordinator needs to decide immediately, not wait for the problem to resolve itself. Silence at this stage causes more damage than an uncomfortable update.
Where to start
Solid on-site coordination doesn't begin on event day — it starts weeks earlier, when the run sheet is built and roles are assigned.
