How to make a team facilitate agile architecture workshops

5 minute read

In The Serverless Mindset, I blogged about Event Storming and Example Mapping for agile architecture. How do you coach teams to adopt these workshops?

3 wonderful workshops that will make your serverless architecture agile

Successfully building a serverless system as a team is far from easy. So, here are 3 DDD workshops for everyone to do collective and incremental architecture.

It’s actually harder to do serverless development with two engineers than it is with one engineer. And [the problem] scales up Nathan Taggart

A few weeks ago, I wrote a guest post for Marco Troisi on his blog, The Serverless Mindset. It presents 3 workshops: Big-Picture Event-Storming, Design-Level Event-Storming, and Example Mapping. It explains how these workshops avoid command-and-control or chaotic architecture in serverless teams. In fact, they unlock a middle way that is calmer, more collaborative, and more effective! It’s agile architecture!

As much as management wanted to benefit from Agile, they didn’t want to give up control. They could not give up micromanaging. It was more important for them to be in control than it was for the company to be successful. (Someone on

I stopped believing in team self-organization long ago. […] There are amazing individuals who can do it, and I worked with them. Those usually make up 5-10% of the team. (Someone on

I needed to go out on medical leave for a while, and when I came back, every single practice I had introduced got rolled back, with expected results. (Someone on

Guess what? These challenges and workshops are not restricted to serverless contexts. So most teams will find agile architecture helpful.

As coaches, our job is not to facilitate these workshops (despite what we are often asked 😕). Our job is to make these workshops a habit in the teams! So how do we coach teams to run these workshops regularly by themselves?

Wouldn’t it be great if you knew how to coach teams to do transparent and collective architecture?

How to teach Event Storming

Big-Picture Event Storming

Big-Picture Event Storming is a whole-team workshop whose purpose is to visualize everything! It’s about sticking all the domain events of the system on a giant design board. It’s Domain-Driven Design in practice! It transfers tremendous knowledge between the domain experts and the developers.

Event Storming can achieve over a few days what would take months with traditional architecture. The idea is not to get a perfect up-front architecture. Instead, it’s to design just enough for everyone to pull in the same direction.

I can think of 3 learning steps to be able to teach Event Storming to a team:

  1. Facilitating Event Storming yourself
  2. Injecting Event Storming into your team as a team member
  3. Finally, installing Event Storming into the organizations that you are coaching

I already wrote about how to facilitate Event Storming workshops. I also wrote about how to inject Event Storming into your organization.

The third step is particularly tricky because the workshop often lasts for a few days. As a result, people will be afraid to take on the facilitation!

Let’s see how to hand over the facilitation to the team.

Start with Immersion

A road sign written "New Skills Training". Training a team to Event Storming is like training any new skill. Generate awareness, and accompany motivated people until they are ready!

It’s useless to expect someone else to help with the facilitation during the first Event-Storming. People usually see it as an ‘extraordinary’ event that is not worth learning.

Don’t bother and facilitate the workshop yourself! As often as you can, remind them that they should regularly re-run this workshop themselves.

Use this first taste of Event Storming to spot people who “get it.” Then, after the workshop, try to involve these people in facilitation and agile architecture.

Repeat Shorter Event Storming Workshops

Take the habit of suggesting short Event Storming workshops:

These smaller-scale workshops don’t need to involve everyone.

As soon as the team agrees to run another workshop, find someone to help you with facilitation. Take 2 hours with your apprentice facilitators to rehearse a simple scenario.

Continue suggesting regular Event Storming. The next time you run the workshop, handover facilitation completely. Be present as a backup, though. When that works well, you have successfully made Event Storming a habit in the team.

Example Mapping

Example Mapping

The promise of serverless is that the cloud provider will take care of all the plumbing for you. This means that your lambdas should contain almost only domain-oriented code. Example Mapping is a neat activity to clarify the Lambda’s business rules.

Example Mapping only takes 20 minutes, so you can run it very often. For example:

  • When starting a new user story.
  • Or after a Design-Level Event-Storming, to clarify what happens inside an aggregate.

Example Mapping is a structured conversation between Developers and Domain experts. Other specific profiles (e.g. quality engineer) can also join if need be.

Here’s a detailed guide about how to inject Example-Mapping into a team. The practice is simple, so people should be able to adopt it quickly.

Example of the typical cards, colors, and layout that we use in Example Mapping Picture from Cucumber blog

Some teams will find Example Mapping is overkill for their context. So don’t hesitate to simplify it to accommodate the team’s constraints. For example, replace Gherkin with literate programming tests.

Make these workshops a habit!

Don’t wait!

Are you involved with building a serverless system? Whether you are just starting or already deep in, you should run a Big-Picture Event Storming! It’s a starting point that will lead you to Design-Level Event Storming and Example Mapping. These workshops will result in:

  • Alignment between everyone.
  • Just-enough architecture to keep your system healthy and to avoid centralized decision-making.

Photo of a man plunging in the sea. The first step to coaching Event Storming, Example Mapping, or any collective agile architecture workshop is to immerse the team in a first experience!

Is a team you are coaching leaning towards command-and-control or chaotic architecture? Suggest Event Storming or Example Mapping to do more agile architecture! Remember the 3 steps to make these workshops a team habit:

  1. Start with immersion
  2. Spot early adopters and potential facilitators
  3. Involve them more and more in regular sessions
