Description

In the world of modern software design, we are confronted with multidimensional complexity—an entangled interplay between business needs, organizational constraints, and technical intricacies. We tend to see this complexity as a problem to be solved, rather than a beautiful mess to be navigated and draw deep learning from.

Jacob Needleman once remarked: “Our culture has generally tended to solve its problems without experiencing its questions.” Can we practice modeling and design in a way, so it is less about defining a target architecture or making a decision, and more about fostering spaces for deep inquiries about the why, the what, the for whom, and the with whom? Sociotechnical paradoxes - stability vs. emergence, order vs. chaos, and getting stuck to get unstuck - are not contradictions to be eliminated but opportunities to be engaged with.

In this talk, we delve into how collaborative working sessions, enriched with meaningful inquiry, storytelling and sense making, can become part of our modeling and design toolbox. They might get us closer toward both social and technical coherence through lived experiences of parts connecting with the whole. We explore how to practice inquiry-driven architecture to catalyze shared understanding and aspirations, build rich relations while profiting from diversity, uncertainty and ambiguity.

To co-create innovative products and sophisticated software, we must compose it like a dynamic music performance — balancing the clarity of written notes with the raw, transformative power of our collective listening and improvisations. Success depends on blending clear, disciplined plans with the creative energy of real-time collaboration. Only by embracing uncertainty, pain, and the beauty of our messy, shared reality can we unleash our collective imagination, co-create products and software that can brave our time’s unique challenges.
