5 Fatal Mistakes in Corporate Events That Indonesian Companies Keep Making

Mistake 1: Choosing a Vendor Based on the Lowest Price

Selecting an EO based on the lowest price is the most expensive false saving in this industry. A Rp 50 million difference in the initial proposal can turn into a Rp 200 million difference in repair costs, do-overs, or reputational damage. A cheap vendor often means undertrained crew, poorly maintained equipment, or subcontractors who have never worked together before.

A better evaluation method: request a portfolio of events at a similar scale, contact references directly (not the names the vendor provides, but contacts you find through your own industry network), and ask specifically about how they handled problems that arose on the day. A good vendor has stories about crises that were managed well. Not a vendor with no problems at all.

Healthy price competition happens when three vendors of equivalent qualification are competing for the same brief. Not when one premium vendor is being compared against two under-resourced ones. Compare like with like.

Mistake 2: A Brief That Is Too Vague

A brief that says "we want a fun and memorable team building for 150 people" is an instruction to produce a generic event. Vendors cannot read minds. They will propose what is easiest to sell and most profitable for them, not what best fits your company's specific needs.

A good brief answers: what are we celebrating or resolving together? Who is the audience, by seniority, by division, is this a cross-hierarchical mix or a single level? What do we specifically not want (equally important as what we do want)? What is the one thing every attendee should feel when they leave? What would indicate that this event succeeded?

Invest one to two hours in writing a solid brief. A good brief saves three to five hours of proposal revision cycles, and often saves tens of millions in scope that was never well-targeted.

Mistake 3: No Clear KPIs

An event without KPIs is an event without accountability. If the only measure of success is "everyone showed up" and "the food was good," you will never know whether a Rp 500 million event produced anything meaningful for the business.

Relevant KPIs for a corporate event: attendance rate vs target (and the reasons behind any absences), NPS or satisfaction score from a post-event survey, the percentage of attendees who can identify at least one key message that was intended, and measurable behaviour change within 30 to 60 days post-event (relevant for town halls or events with a change agenda).

KPIs must be set before the event, not after. Setting KPIs after the event is over is like drawing a target after the arrow has already been released. Data collected without a measurement objective cannot be used for improvement.

Mistake 4: Starting Preparation Too Late

Starting preparation four weeks before a 500-person annual gathering is not preparation. It is crisis management that started slightly too early. Almost every decision made under pressure produces results that are more expensive, lower quality, or both.

Realistic preparation timelines based on scale: events under 100 attendees need a minimum of four to six weeks; 100 to 500 attendees need eight to twelve weeks; above 500 attendees, or with a travel component (out-of-town gathering), need a minimum of sixteen weeks. These are not inflated numbers. They come from the field experience of hundreds of events.

Starting earlier does not mean working harder. It means having more choices, more negotiation time, and fewer decisions made because no alternative exists.

Mistake 5: Ignoring the Post-Event Phase

The event ends when the last guest leaves the room. But the impact of the event, positive or negative, begins precisely after that. Companies that ignore the post-event phase throw away a significant portion of the value they already invested.

The minimum that must happen within 72 hours of the event: send materials or a summary to all attendees and those who could not attend, follow up on any commitments or promises made during the event, and send a short satisfaction survey to capture data before memory fades.

Within 30 days: review all data and feedback, hold an internal debrief with everyone involved, document the lessons learned, and begin planning for the next event using the input from this evaluation. Companies that do this have events that improve each year. Those that do not repeat the same mistakes with the same budget.
