Key Takeaways
- 80% of show-day problems originate in pre-production decisions — or the absence of them
- The five highest-risk pre-production gaps: speaker content not submitted, HVAC not coordinated with catering, loading access not confirmed, venue exclusivity clauses not reviewed, no contingency budget allocated
- Pre-production lock (when all items below are confirmed) should occur 72 hours before load-in — not on load-in morning

Room dimensions and display sizing
The first page of an AV specification contains: room dimensions (length, width, ceiling height), seating configuration and approximate density, the viewing distance from the screen to the furthest seated delegate, and the ambient light level. These four inputs determine: the display technology (LED wall or projection), the screen size (the furthest viewing distance divided by 8 gives the minimum screen height in metres — a 24-metre-deep room needs a minimum 3-metre-high screen), the projector output in lumens (or the LED wall brightness in nits for a given ambient light level), and the PA system type (point-source or line array depending on room geometry).
Signal flow documentation
A signal flow diagram shows how every source (laptop, playback device, microphone, camera) connects to every destination (FOH PA speaker, confidence monitor, LED wall, recording device). It does not need to be an elaborate schematic — a clear table with source, device, and destination for each signal path is sufficient. The purpose: when a signal is not reaching its destination on show day, the signal flow document tells the AV engineer exactly which cable, device, or connector to check. Without a signal flow document, the diagnosis is exploratory — and the exploration takes time that is not available on show morning.
Microphone specification
A complete microphone specification for a 500-person conference lists every microphone required: lectern microphone (type — boundary, gooseneck, or podium condenser), presenter wireless lapel or headset (quantity), panel microphone (quantity and type), audience Q&A handheld (quantity), and MC handheld (quantity). The total channel count from this list determines the minimum console input requirements. Add 20% to the channel count for contingency — a 20-channel microphone list should specify a 24-channel minimum console. A conference that discovers on load-in morning that the console has fewer inputs than sources is a conference that will run its technical rehearsal with something broken.
The essential fields
Event objective: One sentence. What does this event need to do? Not "we want a great conference" — "we want 200 CXOs to leave with a shared understanding of our 2026 strategy, sufficient to make aligned decisions at division level." This single field determines every subsequent production decision.
Date, duration, and location: Confirmed date or confirmed range. Duration (single day, multi-day, evening only). Location (city and venue if confirmed, or city and venue type if not).
Guest count and profile: Total expected attendance. Who are they? Internal employees, clients, press, investors, trade partners? Age range, industry background, what they know and expect about the brand.
Budget: A range is sufficient. ₹15–20 lakhs, ₹35–50 lakhs, ₹1–1.5 crores. An honest range allows the production company to design appropriately. A refused budget produces proposals that guess what you can afford — and guess incorrectly 60% of the time.
Programme skeleton: The rough sequence of the day or evening. Not a detailed run of show — a list: opening, 3 keynotes, lunch, 2 workshops, networking drinks, close. This tells the production company the AV complexity and the layout requirements.
Non-negotiables: Whatever cannot change — the date, a specific speaker, a specific venue, a maximum duration. Non-negotiables are production constraints that must be designed around. They should be stated, not discovered.
What good looks like: A reference — a past event, a competitor's event, a conference from another industry — that communicates the production register you're aiming for.
The one thing most briefs omit
The primary outcome. Production companies receive dozens of briefs that describe the event perfectly — venue, guest count, date, programme, budget — and contain no answer to the question: what does this event need to do? Without a primary outcome, the production company designs an environment and a programme. With a primary outcome, the production company designs a tool. The difference is visible in the proposal quality, the event quality, and the post-event assessment of whether the investment was worth it.
