Is event planning a science or an art?

There’s a long-running discussion in the industry that splits neatly down the middle. One camp insists event planning is an art – that the people who do it best work on instinct, simply create emotions within the room and craft moments of magic from a feel for narrative, design, and human energy. The other camp insists it’s a science – that great events come from logistics, measurement, frameworks, and discipline, and that the people who do them best are operations professionals who happen to work in marketing.

Both camps are right, of course. But neither is enough on its own.

The art case

The art is real, and it matters. A good event opens with a precisely judged silence; a great one ends with a moment guests are still talking about, perhaps years later. That doesn’t come from a checklist. It comes from creative direction, narrative instinct, an eye for room dynamics, and the kind of taste that takes a decade to develop. Events that win awards win them on these grounds.

Without the art, you have a meeting.

The science case

But art alone doesn’t get you to smooth, engaging events. Art alone doesn’t tell you whether your suppliers pay a living wage, whether your delegate travel mix is improving year-on-year, or whether your sustainability narrative is something you can defend in front of a client’s ESG team. Art alone doesn’t survive a Freedom of Information request from a sustainability journalist or a procurement question from a Fortune 500 buyer. For that, you need science: measurement, evidence, frameworks, repeatable methods.

We had a bit of fun recently – laying all of our responsible-delivery factors out in the style of the periodic table of elements. Ninety factors, three rows of thirty, colour-coded against the three ESG pillars. It looks the part. It is also, deliberately, a joke at our own expense – nobody is going to use a wall chart to plan a conference. But the chart makes a point that’s harder to argue with once you see it written out: there are ninety different things that quietly underpin a single sentence in a sustainability report. Carbon and travel. Power and lighting. Local supply chain and food approach. Locality and accessibility, wellbeing and fair pay. KPIs and risk assessment and named accountability and lessons learned. That’s the size of the science problem – across the whole event ecosystem.

Now both the art and the science can be measured.

But here’s the relief: no single person is running ninety decisions. The ninety divide cleanly into three sets of thirty, and which thirty you own depends on your role. An event planner owns one set. An AV or production supplier owns another. A venue operations or sales planner owns the third. If you’re any one of those people, you’re running thirty small decisions, not ninety. Which is a much more manageable science problem to start with.

Three lenses on the same event

The ninety factors don’t all sit with one team. They sit with three. event:decision’s Impact suite is structured as three lenses on the same event – each tool covering one of those three sets of thirty factors, each pointed at one function:

Impact: Event is the lens for the event itself. Carbon, attendee and crew travel, waste, food approach, biodiversity, locality and inclusion, wellbeing, legacy, KPIs and ROI, sustainability leadership, governance and accreditations. This is the tool for event organisers, in-house event teams, brand experience leads, and the agencies running events on their behalf. If you commission, design, or run the event, Impact: Event is for you.

Impact: AdVantage is the lens for the Technical Production and AV chain. Power and lighting specification, project carbon, vehicle movements, reusable build, subcontractor briefing, welfare provisions, local crew, fair pay, working hours, RAMS, compliance documentation, named accountability. This is the tool for production agencies, exhibition contractors, AV suppliers, stand builders, freight and logistics partners – the people who turn the brief into a physical reality. It gives suppliers a structured way to evidence what they’ve done, and gives organisers a clear standard to procure against.

Impact: VenueLens is the tool for the venue. Mass transport access, renewable energy, water management, single-use plastics, F&B approach, delegate accessibility, venue fair pay, inclusion hiring, community projects, surplus distribution, public reporting, supplier due diligence, ESG targets. This is the tool for venues themselves – operators, conference centres, hotels, stadiums, exhibition halls. It lets venues show with evidence what they actually deliver, and gives organisers a like-for-like way to compare venues at the procurement stage.

Why three tools, not one

Because both spend and responsibility in events don’t sit just with one party. The event organiser commissions and pays for the show. The suppliers and agencies deliver it. The venue hosts it. Each controls a different slice of the impact picture, and a single tool aimed at any one of them would miss most of the footprint.

Between them, the Impact suite covers approximately 98% of event spend – the client commission, the supplier delivery, and the venue cost together account for nearly every pound that flows through an event. The remaining 2% is the long tail of incidental costs that, even if measured, would not materially change the conclusion.

So — science or art?

Both. Always both.

The art is what makes an event worth attending. The science is what makes it responsible and sustainable. The art delivers the moment of magic in the keynote, the goosebump from a perfectly cued lighting state, the gasp at the reveal. The science delivers the carbon report your client’s CFO can put in their annual filings, the accessibility statement your delegate community can trust, the legacy figure your sponsor can quote to their board.

You don’t choose between them. You do both – or you fall behind the audiences, the clients, and the regulators who increasingly expect both.

And it turns out that both looks a lot like thirty small decisions for the planner, thirty for the supplier, thirty for the venue – and ninety in total across an event that used to run on instinct alone.
