Talking Points

Recent interactions between the hosts and their guests.

#52 - Makoto Kern: Feature-centric to user-centric - UX Design to navigate global challenges and the “AI Competence Mirage”

Q: Can you explain the difference between UX and UI and why it matters in practice?

UX is about the end-to-end user journey and how easily users achieve their goals, while UI is the visual layer; great UX can exist with simple visuals, and even a visually strong interface can fail if the underlying workflow is poorly designed.

#49 - Nadja Kunz: Towards water stewardship in mining, understanding critical minerals, safer and sustainable resource management

Q: What does the word innovation truly mean in your work and how has it shaped your challenges?

Innovation means not just having ideas but implementing them with supporting systems to move them forward, turning concepts into action.

#53 - Alma Schellart: Making data open, making models talk and embracing uncertainty to solve 100-year old urban drainage challenges

Q: What's your view on the role of monitoring versus models in the future of urban drainage?

We need both. Monitoring provides real-time visibility and trust, while models help scenario analysis and design. The goal is to use them together to understand uncertainty, calibrate decisions, and enable adaptive solutions within regulatory constraints.

#53 - Alma Schellart: Making data open, making models talk and embracing uncertainty to solve 100-year old urban drainage challenges

Q: What are the challenges of open data in this field, and how can we ensure it improves trust rather than eroding it?

Open data must come with context, metadata, and governance. Without that, stakeholders misinterpret trends and media can spin narratives that damage trust. Brussels' collaborative approach shows how to guide interpretation and connect data with practical actions.

#53 - Alma Schellart: Making data open, making models talk and embracing uncertainty to solve 100-year old urban drainage challenges

Q: How do you define uncertainty in your work, and why is it important for designing urban drainage systems?

Uncertainty is about the differences between measurements, model structure, and what we can know about future conditions. It matters because decisions, especially about large investments like tanks or blue-green infrastructure, depend on understanding these uncertainties to avoid over- or under-building.
