Let’s talk about how event storming can be a game-changer when you’re dealing with enterprise tech solutions and considering an event-driven architecture (EDA).

Scene: You’re working within a large enterprise, and are starting a massive project. Essentially, it feels like you are putting together a 5,000-piece puzzle with no picture on the box. Sounds daunting, right? Here’s where event storming can swoop in and save the day.

Event storming is essentially a collaborative workshop practice that brings developers, domain experts, and stakeholders together. It gets everyone on the same page and shifts the focus from ‘what do we need to build’ to a ‘what is actually happening’ mindset. Instead of drowning in documentation and getting lost in the weeds, you dive straight into the core of your business processes.

You start with the most significant business events, which are the big moments that represent a change or a notable action within a business process. For example, consider “Order Placed” or “Invoice Generated.” Each event is a sticky note, quite literally, that you slap up on a big board or wall.

What’s magical here is that each event often triggers other events. Orders don’t just sit there. Maybe they create inventory tasks or flag accounting to generate an invoice. Suddenly, you’re looking at not just isolated events but a sequence of them, defining your business operations.

Event storming is perfect for identifying boundaries and services in a microservices architecture, which is what event-driven architectures complements. You start seeing natural aggregation points where it makes sense to split responsibilities into independent services, each handling its unique bit of the process.

This helps in deciding data ownership and flow. In an EDA, knowing who owns what data, and how it flows between events, is crucial. During event storming, these questions get asked, and because the whole team is there, they’re answered collaboratively. Everyone knows who owns each piece of the puzzle.

Also, with everyone involved, you spot potential bottlenecks, orchestrations, and integration spots early on. The architect might identify where scalability could become an issue, or where latency might creep in, while business folks might suddenly realize areas where processes overlap, or aren’t as efficient as they thought.

In a nutshell, event storming lays down the blueprint for your event-driven architecture. It aligns your tech landscape closely with business needs, ensures everyone has a stake in the design, and creates a dynamic map for how events flow through your business.

So, next time you’re staring at that daunting project board, gather your team for an event storming session. You might be surprised how quickly clarity starts to emerge, and you’ll have a solid foundation to inform those crucial architectural decisions moving forward. It’s like having a cheat code for unravelling complexity.
