Designing for Relevance: How UX Helps People See What Truly Matters
Designing for Relevance: How UX Helps People See What Truly Matters
In an age of information overload, great design isn’t just about clarity or beauty, it’s about relevance.
My work explores how cognitive science, algorithmic thinking, and human intuition come together to help users focus on what’s meaningful in the moment.
"Cognitive Design Series - Exploring Relevance Realisation in Complex Systems"
The Relevance Realisation Framework
The Relevance Realisation Framework
Relevance Realisation (RR) describes how humans instinctively filter complexity - noticing what matters, ignoring what doesn’t.
In UX, RR becomes the foundation for designing clarity at scale: it bridges algorithmic structure (rules, data, precision) and heuristic flow (intuition, perception, adaptability).
"Design is the art of aligning system intelligence with human attention."

Problem Context – The Weight of Data
Problem Context – The Weight of Data
Waterloo’s engineers relied on static performance charts to select air diffusers, accurate but cognitively demanding.
Each chart required mental interpolation across parameters like flow rate, static pressure, and noise levels.
Pain Points
Fragmented PDFs & inconsistent diagrams
Slow manual estimation
Steep learning curve for new engineers
“They didn’t need more data, they needed more relevance.”

Key Insights
Experts filter visually, they don’t read numbers linearly, they see patterns.
Speed depends on cognitive framing, knowing what parameter to prioritize.
Decision confidence > precision, users trust results when the path feels clear.

Thinking Framework – Algorithmic Meets Heuristic
Algorithmic Thinking
Algorithmic Thinking
Each performance curve follows a deterministic model. The algorithmic layer defines structure, such as the parameters, relationships, and permissible limits.
Heuristic Thinking
Heuristic Thinking
Engineers use mental shortcuts for spotting shape, slope, and trend. The heuristic layer defines understanding, what feels relevant right now.
“Relevance Realisation connects these two worlds, highlighting what truly matters for the current decision.”

Algorithmic thinking ensured correctness.
Heuristic sensitivity ensured understanding.
Together, they created cognitive trust which is the foundation of expert UX.
“When design aligns with cognition, even complexity feels effortless.”

Problem Context – The Maze of Defects
Problem Context – The Maze of Defects
Amazon’s defect management involved hundreds of condition-based flows.
Each defect type branched into multiple nested rules.
Teams struggled not with accuracy, but with relevance: which rule applied right now?
The question wasn’t just ‘What’s the next step?’ - it was ‘Which step matters most now?’

Relevance, Not Rules, Drives Better Decisions.
Relevance, Not Rules, Drives Better Decisions.
UX’s role isn’t to simplify everything, it’s to structure complexity around human cognition.
The decision tree’s strength came from its dialogue between precision and intuition.
It’s not just an operational tool, it’s a thinking partner.
“Every great system learns to think like its users. Every great UX helps users think like the system.”
