*This event is a collaboration with our friends from Domain Driven Design Berlin, check out their Meetup page [here](https://www.meetup.com/de-DE/domain-driven-design-berlin/) and sign up there!* \-\-\-\-\- **About the evening** Back in August, we explored how Design Thinking can help us uncover and validate the right problems. But even when we agree on what to build, things often go wrong, not because of bad solutions, but because we don’t fully understand what the problem actually means in practice. In this session, we’ll build on that idea and focus on the next step: turning vague ideas into something concrete, shared, and testable. Using Example Mapping - a lightweight technique from Behaviour-Driven Development (BDD) - we’ll work in small groups to: * Break down a feature into rules, examples, and questions * Surface hidden assumptions and edge cases * Align on what the behaviour of a system should actually look like If the previous session was about finding the right problem, this one is about understanding it well enough to build it right. This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there! **RSVPS:** **Please sing up on the event page from [Domain Driven Design Berlin](https://www.meetup.com/de-DE/domain-driven-design-berlin/)!** \-\-\-\-\-\- **Code of Conduct** We adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/) to ensure a welcoming and respectful environment for all participants.

Emissionsdaten aus verschiedenen Quellen erfassen, zusammenbringen, aggregieren und visuell darstellen. Eine Anforderung, die in vielen Unternehmen existiert und sich alle wünschen. Wie das geht, zeigt Stefanie am Beispiel des GreenOps Reports für die EnBW. Sie erläutert ganz praktisch welche Datenquellen (Azure, AWS, Datacenter, Endgeräte) an das Power BI Reporting angebunden wurden und welche Quellen noch in Zukunft angebunden werden. Das ermöglicht ein vollständiges Bild zum IT Fußabdruck der EnBW zu erhalten. Zudem zeigt sie auf, wie sie bei der Validierung der CO2e Zahlen in Zusammenarbeit mit externen Firmen wie resilio und eco:digit vorgegangen ist und auf welche Ergebnisse die EnBW bei der Validierung gestoßen sind. Der Abend wird ein Mix aus Praxis-Bericht, Show Cases und How-To sein. Am Ende haben wir alle einen Überblick, wie man die Emissionen der großen Hyperscaler, On-Prem Rechenzentren und weitere Quellen erfasst und in einem Dashboard visualisiert. **Agenda** 18:00 Einlass & Networking 18:30 Vortrag mit einer kleinen Pause zwischendurch 21:00 Ende & Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Green Software Development Karlsruhe ist ein unabhängiger Teil der globalen [Green Software Foundation](https://greensoftware.foundation/) Community.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
