What is an Event Debrief?

An event debrief (also called a post-event review or wash-up) is a structured review held after an event, where the team captures what went well, what went wrong and what to change for the next event. It is how festivals, venues and organisers learn from each event, and is often expected by licensing authorities after larger events. Even small events benefit from a short debrief.

How to run an event debrief

A good debrief follows five steps:

  1. Hot debrief: hold a short meeting straight after the event, while details are fresh.
  2. Collect feedback: gather notes from every team, supplier and the event control log.
  3. Cold debrief: a few days or weeks later, hold a fuller review with figures and reports.
  4. Agree actions: decide what to change, who owns each action and by when.
  5. Feed forward: update plans, the risk assessment and the event management plan for next time.

Debriefs work best with accurate data on what actually happened, which teams pull together with the Report Center in Crescat.

Hot debrief vs cold debrief

A hot debrief happens straight after the event, often on site, to capture immediate issues and thanks. A cold debrief happens later, with time to review data, feedback and incident reports, and leads to the main decisions.

What to cover in an event debrief

  • Safety incidents and near misses
  • Crowd flow, queues and capacity
  • Production and technical issues
  • Staffing levels and performance
  • Supplier performance
  • Audience and artist feedback
  • Budget against actual costs and income
  • What to keep doing, not just what to fix

Frequently asked questions

Who should attend a debrief?

The heads of each team, key suppliers and, for larger events, the local authority and emergency services. Smaller events can run a debrief with just the core team.

How do you keep a debrief useful?

Keep it focused on learning, not blame. Record actions with owners and deadlines, and check them before the next event. Sharing a short written summary keeps everyone on the same page.

When should a debrief happen?

A hot debrief on the day or the next morning, and a cold debrief within a few weeks, before memories fade and planning for the next event starts.
