The event is over. Everyone has gone home. Now it is time to find out if it worked.

So you send a survey.

‘On a scale of 1 to 10, how satisfied were you with the event?’

‘Would you recommend this event to a colleague?’

‘How would you rate the venue, catering, speakers and overall experience?’

A few days later the results come back. The average score is 8.2 out of 10. Eighty-seven percent of respondents said they would recommend the event. The venue and catering both scored above 8.5.

Success, right?

Maybe. Maybe not. Because none of those numbers tell you whether the event actually did what it was supposed to do.

Satisfaction is not impact. Enjoyment is not change. And most post-event surveys are designed to measure the wrong thing.

The Problem with Satisfaction Scores

Satisfaction scores tell you whether people liked the event. That is useful information. It is just not the same thing as whether the event worked.  You can have a room full of satisfied people who leave, do nothing different and forget the event two weeks later. High satisfaction, zero impact. 

Or you can have an event that made people uncomfortable, challenged their assumptions, forced difficult conversations and three months later behaviour has shifted, decisions have been made and real change has happened. Lower satisfaction scores, high impact.

The two do not always align.

Satisfaction measures the experience. Impact measures the outcome. Most surveys only ask about the first.

They ask: Did you enjoy the keynote? Was the venue comfortable? Was the food good? Did the day run smoothly?

They do not ask: Did you change your mind about something? Did you do something differently afterwards? Did this event shift a number that matters to your organisation?

If the brief said the event needed to drive sales behaviour, member renewals, leadership alignment or partner investment, then satisfaction scores are at best a proxy and at worst a distraction.

What Satisfaction Surveys Actually Measure

Satisfaction surveys measure logistics, delivery and mood.

Did the event feel professional? Were there any visible problems? Did people leave feeling positive?

That matters. If your event is chaotic, uncomfortable, or poorly run, people will not engage with the content. Logistics are the foundation. But they are not the outcome.

The problem is that most satisfaction surveys stop there. They measure whether the event was pleasant, not whether it was effective. Here is what a typical post-event survey looks like:

 – Overall satisfaction: 1-10 scale

 – Quality of speakers: 1-10 scale

 – Venue and catering: 1-10 scale

 – Likelihood to recommend: 1-10 scale

 – Any additional comments: open text box

That survey will tell you if people were happy. It will not tell you if anything changed.

And because satisfaction scores are easy to collect, easy to report and generally positive, they become the default metric. Event teams present an average satisfaction score of 8.2 and call it success, even if the event failed to move the one thing it was designed to move.

The Questions Most Surveys Do Not Ask

If you want to know whether an event had impact, you need to ask different questions. Not just about the day itself, but about what happened afterwards.

Instead of ‘How satisfied were you?’, ask:

Did this event change your thinking about something? If so, what? This question captures whether the content landed, whether new ideas were introduced, whether beliefs shifted.

Have you done anything differently since the event? This is the behaviour change question. If the event was designed to shift how people sell, lead, collaborate or prioritise, this question tells you whether it worked.

Did this event help you make a decision you had been delaying? Events often exist to unblock things that are stuck. If people are making decisions faster or more confidently after the event, that is impact.

Three months from now, what do you think will be different because you attended this event? This is a predictive question, but it forces people to think beyond the day itself and consider lasting effects.

Who else needs to hear this message and have you shared it with them? If the event is working, people will talk about it. Not just ‘I went to an event,’ but ‘here is what I learned and here is what we should do differently.’

None of those questions appear in standard satisfaction surveys. And none of them can be answered on the day the event ends.

Timing Changes

Most post-event surveys go out within 24 to 48 hours of the event finishing.

That makes sense if you are measuring satisfaction. People’s memories are fresh. Response rates are higher. You get clean data on logistics and delivery. But if you are trying to measure impact, 48 hours is too early.

Impact shows up weeks or months later. Behaviour does not change overnight. Decisions take time to implement. Strategic shifts play out over quarters, not days. If you only survey immediately after the event, you are measuring reaction, not result.

A better approach is to survey twice. Once within 48 hours to capture satisfaction, logistics and immediate reaction. Then again 6 to 12 weeks later to capture behaviour change, decision-making and lasting impact.

The second survey is harder to execute. Response rates drop. People have moved on. It requires more effort to track and follow up.

But that is where the real evidence lives.

What Good Impact Questions Look Like

Here are a few examples of impact-focused survey questions that go beyond satisfaction:

For a sales conference:

Since the event, have you changed the way you position product/service in customer conversations? If yes, how?

Have you closed any deals that you attribute, even partly, to what you learned at the conference?

Looking at your pipeline now compared to before the conference, has anything shifted in deal size, velocity, or win rate?

For a member congress:

Since the event, have you increased your engagement with organisation? For example, attended more programs, referred new members, or participated in advocacy efforts?

Has your perception of the value of membership changed since attending?

Are you more or less likely to renew your membership based on what you experienced at the congress?

For a leadership summit:

Since the summit, have you implemented any of the strategies or changes discussed? If yes, which ones?

Have decisions been made faster or more confidently in your team since the summit?

Has alignment improved among your leadership group since the summit? If yes, in what way?

These questions are specific. They tie directly to the event’s purpose. And they ask about behaviour, not mood.

Why Most Organisations Do Not Ask These Questions

If impact questions are more useful than satisfaction questions, why do most surveys still default to satisfaction?

Three reasons.

First, satisfaction surveys are easier. The questions are generic. They work for any event. You can use the same template every time. Impact questions require customisation. You have to know what the event was trying to achieve and design questions that match.

Second, satisfaction scores are safer. They are almost always positive. An average score of 7.5 or 8 looks good in a report. Impact questions are riskier. They might reveal that nothing changed. That is harder to present to a CEO or board.

Third, many organisations do not define impact before the event happens. If you do not know what success looks like in advance, you cannot measure it afterwards. So you default to measuring what is easy: satisfaction.

What This Means for Your Next Event

Before you design your next post-event survey, go back to the brief and ask: what was this event supposed to change?

If the answer is clear: sales behaviour, member renewals, leadership alignment, partner investment, then design your survey to measure that change, not just whether people enjoyed the day.

Survey twice. Once immediately to capture satisfaction and logistics. Once 6 to 12 weeks later to capture behaviour, decisions, and lasting effects.

Ask specific questions tied to the event’s purpose. Not ‘were you satisfied?’ but ‘what did you do differently?’

And be prepared for the answers to be less flattering than satisfaction scores. Impact measurement reveals what worked and what did not. That is uncomfortable. It is also the only way to improve.  Because if all you measure is whether people were happy on the day, you will never know whether the event actually mattered.
