What do you do if things are slow to start?
The workshop can be slow to start. Participants can get lost in the chaotic nature of Event Storming.
A typical symptom is when people discuss in small groups and don’t stick domain-events.
In this case, go to the groups to trigger action. Make sure they understand the instructions. Kindly ask them to stick events as soon as possible. You might even add a bit of pressure by explaining that we’ll be doing a first event review in 10 minutes.
What to do if there is a single discussion bottleneck?
Sometimes, all participants become the audience to a central dialog.
It’s often because a unique person knows some crucial information. In this case, you have no choice but to wait.
Sometimes, though, it happens for no reason. Intervene and split the group into two groups to work on two halves of the board. This implies merging and synchronizing at the end, but it’s a small price to pay to keep everyone engaged.
How can you avoid being a PITA when stickies are poorly written (Post-it twist)?
Here’s one from Alberto Brandolini. Stickies, in particular domain events, are often of poor quality initially. People need a bit of time to distinguish an event from a command.
Harassing them to rewrite their stickies won’t work!
Here is Alberto’s trick: whenever you notice a low-quality sticky, flip it 45°. When people ask why it is flipped, repeat event-writing best practices and ask someone to rewrite the faulty domain-event sticky. With time, people will learn how to write good domain events, and the quality of what’s on the board will improve.
How do you make decisions explicit?
A significant strength of Event Storming is that you will make many decisions during the workshop. Given the large audience, some people will ‘miss’ some decisions. It’s also a good idea to keep track of these decisions to avoid forgetting them.
I tried using special sticky notes to track decisions but to no avail. In the end, Alberto shared his trick.
Depends on the decisions, and on the context. Usually putting decisions on a flip chart and sharing pictures might do the trick.

The simplest and most effective thing is to keep a flip chart close to the design board and record decisions there. At the end of the workshop:
- Take a photo of the board
- Save it somewhere
- and share it with a broader audience
What does “Make the Design Space Infinite” mean in practice?
💡You’ll need even more infinite design space for Design-Level Event Storming 😉
Stickies are great because we can move them around many times. During Design-Level Event Storming, participants often insert new stickies between existing ones. They’ll need a bit more design space every time they do this, and that’s when ‘Infinite Design Space’ takes all its meaning. Another situation is if stickies start to be aligned vertically rather than horizontally. Remember that Shared understanding relies on common metaphors.
As the facilitator, you need to be proactive:
- Pause the workshop
- Explain the need for more space
- Add more design space by claiming more of the wall (left, right, or even above or below)
- Move the stickies to keep the design clear. It’s quick if you ask everyone to contribute.

How do you make sure to always leave with actions?
Here is one thing you don’t want:
- Run your Event Storming,
- Build some shared understanding…
- …and do nothing with it!
It’s crucial to leave the Event Storming with actions.
During the workshop, you used pink stickies to capture subjects you could not solve on the spot. These might be questions, quick fixes, or problems.
Before closing the session, take 30 minutes to agree on the next steps. A good way is to go through all these pink stickies. There might be homework for a follow-up workshop, tickets to add to the team’s backlog, or experiments to run. Make sure these items are actionable tasks with an accountable person for each.
Whatever your issue, adding special stickies is usually a bad idea
Before getting Alberto’s advice about logging decisions, we tried using custom “decision” stickies. That did not work well. Event Storming already has an extensive color code for stickies; adding more is too much. (Note: It’s almost impossible to find a sticky color that is not already used, anyway!)
When we tried this, people would make decisions but forget to record them with stickies.
💡If you are considering adding a new kind of stickies, look for another idea!
How do you represent Event Loops in the design?
Any real-life domain contains some feedback loops. Drawing arrows on the design board won’t work as it prevents us from moving the stickies around later. Instead, you can model loops with duplicate stickies:
- A classic event sticky to where the event happens (usually to the right)
- A duplicate sticky with an arrow where the event feeds back into the system (usually to the left)
