Many leaders know the feeling: you invest heavily in a new digital product (an app, an online store, an internal platform...), but the delivery is delayed, exceeds the budget or does not meet the original business goals.
The cause often lies not with the developers, but with a fundamental problem: a lack of a shared vision about how your company works. At Lemon, we tackle the root of this problem and transform your software from a cost into a strategic growth pillar. In doing this, we combine two powerful methods that leverage each other's strengths: Event Modeling and Event Sourcing.
Event Modeling — Ending Miscommunication
Building complex software is like building a custom building. Without a perfect blueprint, you end up with a house that has a kitchen in the attic. Event Modeling is that perfect blueprint.
What's in it for a business leader?
Event Modeling is a visual, timeline-based approach that maps out every crucial step in your business process. We use a shared board (digital or physical) to map the customer journey, orders, or transactions.
For example, an order process is visualized as;
1. Experience: A potential customer views the product...
2. Command: ... and click “Checkout”.
3. Event: Order Placement Started
4. View: The customer sees the order confirmation.
The immediate advantage for the Bottom Line:
✅ Guaranteed alignment with business value
Because the CEO, marketer, and developer all look at the same visual timeline, we build the functionalities that add immediate value for the customer and contribute to sales.
✅ Faster & more cost-effective projects
Eliminating misunderstandings in the design phase saves expensive, time-consuming rework later. Indeed, the biggest cost in software is correcting misunderstood requirements.
✅ Risk minimization
You obtain a proof of concept of the entire system's behavior before investing heavily in code.
Event Sourcing — From warehouse to intelligence source
After a clear design using Event Modeling, the implementation strategy follows: Event Sourcing. This is where data changes from a static snapshot to a dynamic, complete history. In a traditional database, old data is deleted or overwritten; only the current the state of affairs is visible. Event Sourcing throws nothing away; instead, it stores every change (event) as an immutable fact.
Why Is Event Sourcing Smarter?
📈 The insight engine for Sales and Marketing: the database becomes a repository of customer behavior.
- Traditional: All you know is that a customer is currently a “Platinum Member.”
- Event Sourcing: You can view the various steps a customer goes through, such as “Customer upgraded membership to Platinum” —> “Customer placed 5 orders in week 37” —> “Ignored loyalty mail”.
Result: The marketing department gets deep insight into the customer's journey and behavior to create hyper-personalized campaigns and promote upselling.
🛡️ The perfect compliance and audit trails: Event Sourcing automatically creates a complete, immutable (audit) history of each transaction. This is essential for:
- Finance: achieving transparency and absolute accuracy in all cash flows.
- Legal requirements: can be demonstrated at any time why a status is as it is, and when and by whom a change was made.
🤖 Future-proof and AI-ready: It's no secret: the future of software lies in Machine Learning and AI
- AI/LLMs need data to 'learn'. The more detailed, chronological behavioral data becomes available, the more valuable the insights and predictions AI can provide.
- Event Sourcing provides the richest and most complete training data to use AI models in the future, for example in churn prediction or automated fraud detection.
Use your most valuable business data effectively.
Building for Growth
By starting with the clarity of Event Modeling and building on the flexible, data-rich foundation of Event Sourcing, we transform software from a purely operational tool into a powerful source of business intelligence that drives sales growth.
