Design isn't just about what we build — it's about how we think. These methods help me slow down, ask better questions, and navigate the messy middle with clarity and confidence. Here's a selection of heuristics and techniques I rely on, time and time again.

Usability Heuristics

When I need to quickly assess an interface or guide a redesign, these are my go-to tools. They help me evaluate clarity, consistency, and usability from a user's perspective — long before usability testing begins.

Method	Why I Use It	Key Questions to Ask
Cognitive Walkthrough	Simulates the user's thought process — helps spot where clarity breaks down. See [Page Flows Cognitive Walkthrough Guide]3.	"What would a user think here?"
Heuristic Evaluation	Still gold for quick wins — reveals issues teams go blind to. See [Jakob Nielsen's 10 Usability Heuristics]1.	"Does this follow established patterns?"
AEIOU Framework	Captures context and behavior quickly during fieldwork ([Open Practice Library]2).	"What activities, environments, interactions, objects, and users are present?"
Accessibility + Retainability	My go-to sanity checks: Will everyone get it? Will they remember it later? See [Quick UX Accessibility Checklist]6.	"Can someone with disabilities use this? Will users remember how to use it after a break?"

Core Usability Factors

These fundamental factors form the foundation of any good user experience. They're the baseline that everything else builds upon.

Factor	What It Means	Why It Matters	Evaluation Questions
Usability	How easily and quickly can a user learn to use the technology when first encountering it?	First impressions matter — if users can't figure it out quickly, they'll leave	"Explain this product to me as if I'm 5 years old"
Accessibility	Everybody (including people with disabilities) can perceive, understand, navigate, and interact with a product equally	Inclusive design isn't just good ethics — it's good business (6)	"Can someone with visual, motor, or cognitive disabilities use this effectively?"
Ease-of-Use	Can the user effortlessly understand and operate the technology?	Reduces cognitive load and frustration	"Does this feel intuitive or do I have to think about it?"
Efficiency	How much effort does the user need to expend to use the product once they've learned it?	Time is precious — efficient interfaces respect that	"How many clicks/actions does this take?"
Retainability	When users return after a break, how easily can they reestablish proficiency?	Most users don't use your product daily	"Will I remember how to do this next week?"
Safety	Does the technology prevent serious errors and allow easy recovery?	Users should feel confident, not afraid to explore	"Am I at risk of making mistakes that are hard to undo?"

Real-world example: When building Koios, a learning platform for 300 students, accessibility became crucial (6). The mobile-first design served emerging markets in Ghana, while the custom dark mode implementation addressed night-time learning needs. This taught me that accessibility isn't just about compliance — it's about serving real users in real contexts.

Meaning & Engagement Factors

Design is emotional. It's about more than flows and features — it's about purpose, belonging, and resonance. These factors help me shape experiences that matter, especially in civic and mobility projects where human connection is key.

Engagement Factors

These factors determine whether users are actively involved and emotionally connected to the experience.

Factor	What It Means	Why It Matters	Evaluation Questions
Narrative	Do you feel as being part of a story when using the product? See [Storytelling in UX]8.	Humans are storytelling creatures — we crave narrative structure	"Do I feel like I'm part of something bigger when using this?"
Activation	The product gives incentives and stimulates active involvement, discovery, and choice	Passive consumption is boring — active engagement is memorable	"Do I feel nudged to discover new things?"
Adaptivity	The product is aware of the user, situation, and context, changing behavior to fit needs	Personalization creates connection and reduces friction	"Does this adapt to my preferences and situation?"
Immersion	The product triggers senses and envelops the user in complete focus	Deep engagement leads to flow states and satisfaction	"Do I feel completely absorbed when completing major tasks?"
Aesthetics	The product appeals to the user's senses and is considered attractive	Beauty isn't superficial — it affects usability and emotional response	"To what extent do I consider this aesthetically pleasing?"
Authenticity	The product is original, genuine, and fits with user values	Users can spot inauthenticity — it breaks trust and engagement	"Does this feel real and aligned with my values?"
Flow	The product creates a seamless path of actions that can be followed easily and smoothly	Flow states are where users lose track of time and feel most satisfied	"Does the interaction feel smooth and uninterrupted?"

Meaning Factors

These factors address deeper human needs and motivations that go beyond basic functionality.

Factor	What It Means	Why It Matters	Evaluation Questions
Popularity	Feeling liked, respected, and having influence over others	Social validation is a powerful motivator	"Do I feel part of a community where I'm acknowledged by others?"
Sense of Purpose	Feeling important to others, helpful, and having something to contribute	Purpose-driven experiences create lasting engagement	"Does this product give me purpose? Can I create impact?"
Relatedness/Belongingness	Having regular intimate contact with people who care about you	Connection is fundamental to human happiness	"Are there meaningful connections with others through this product?"
Security	Feeling safe, in control, and that life is structured and predictable	Without security, users can't relax and engage fully	"Do I feel safe and in control when using this?"
Autonomy/Independence	Feeling that activities are self-chosen and self-endorsed	Users want to feel in control of their own decisions	"Do I feel autonomous and independent in my actions?"
Competence/Effectiveness	Feeling capable and effective in your actions	Mastery and achievement are deeply satisfying	"Do I feel capable and effective when using this?"
Stimulation	Getting plenty of enjoyment, pleasure, and new sensations	Novelty and fun keep users coming back	"Do I feel stimulated and engaged, not bored?"
Self-Actualization	Feeling you have a purpose, acting in conformity with values, becoming who you really are	The highest level of human motivation	"Does this help me become more of who I want to be?"

Real-world example: Toogethr tackled the deeper human need for belonging during post-pandemic commuting. By framing solo car trips as missed social opportunities, the project addressed relatedness and purpose — turning a functional problem (traffic) into a meaningful one (social connection). The 5-Why analysis revealed that commuters weren't just avoiding traffic; they were craving the workplace bonds they'd missed during isolation.

Research Methods I Keep Coming Back To

No two projects are the same — but some research methods consistently give me strong signals. Whether I'm mapping mental models, uncovering friction points, or gathering emotional feedback, these approaches help me make decisions with empathy and evidence.

Discovery & Exploration Methods

These methods help you understand the problem space and uncover hidden insights.

Method	What Fascinates Me	Why I Use It	When to Use It
Love Letter & Breakup Letter	The raw emotional honesty this method uncovers is incredible. When people write to products as if they're relationships, they reveal pain points that structured interviews never touch.	Allows participants to express thoughts and emotions in a familiar format — addressing products they either love or have been disappointed by	Early discovery, understanding emotional relationships with products
AEIOU Framework	It's like having a structured way to be curious. By systematically documenting Activities, Environments, Interactions, Objects, and Users, you catch details that would otherwise slip through the cracks (2).	Captures context and behavior quickly during fieldwork — reminds researchers to attend to the overall setting	Field research, ethnographic studies, observational research
Card Sorting	Watching how people naturally group concepts reveals their mental models in real-time (5).	Reveals user mental models, improves information architecture	Information architecture, navigation design, content organization
Focus Groups	The group dynamics are fascinating — how one person's comment sparks another's memory, creating a richer picture than individual interviews ever could (5).	Capture emotional nuance and peer dynamics, provide deep insight into themes and patterns	Brand research, emotional insights, understanding group perspectives
Contextual Inquiry	There's something magical about watching people work in their natural environment. You see the workarounds, the frustrations, and the moments of flow that they'd never think to mention (5).	Observing people during work to find underlying work structure — understanding flows, sequences, and tools	Understanding work processes, uncovering hidden workflows
Diary Studies	The longitudinal aspect reveals patterns that emerge over time — the daily frustrations that build up, the moments of delight that sustain engagement (5).	Allow insights by documenting participants' daily life with guided questions and creative formats	Understanding daily routines, longitudinal behavior patterns
Cultural Probes	The creative artifacts people create — drawings, photos, collages — often reveal deeper truths than words alone. It's like getting a window into their subconscious (5).	Engaging users in creative opportunities to express feelings, dreams, needs, and desires	Understanding cultural contexts, creative expression of needs

Real-world example: For Toogethr, I used the AEIOU framework (2) to systematically document commuting culture. Activities (solo driving), Environments (traffic jams), Interactions (bell ringing), Objects (bikes, cars), and Users (commuters) revealed patterns that structured interviews missed. The contextual inquiry approach led me to study memes and pop culture references about commuting — uncovering the emotional reality behind the data.

Evaluation & Testing Methods

These methods help you validate assumptions and measure effectiveness.

Method	What Fascinates Me	Why I Use It	When to Use It
Heuristic Evaluation	The consistency of this method is remarkable. Different evaluators often find the same issues, proving that usability problems are real and identifiable (1).	Detect baseline usability problems consistently, can be done independently within a team	Quick usability assessment, identifying breakthrough opportunities
A/B Testing	The scientific rigor is satisfying — changing one variable at a time and measuring real user behavior (5).	Validates intuition with real-world data, very granular testing of different elements	Optimization, hypothesis testing, design validation
Usability Testing	Watching someone struggle with your design is humbling and enlightening (5). The "think aloud" protocol reveals the gap between what you think users will do and what they actually do.	Identify usability issues, understand user behavior and mental models	Design validation, identifying usability problems
Desirability Testing	The emotional language people use to describe experiences is fascinating (5). Words like "comprehensive," "professional," or "complex" reveal the emotional impact of design decisions.	Determine desired design direction through emotional adjectives, resolve design disagreements	Design direction validation, emotional impact assessment
Cognitive Walkthrough	Stepping into a first-time user's shoes reveals assumptions you didn't know you were making (3). It's like debugging your own thinking.	Evaluate whether an interface is understandable and easy to learn for first-time users	Interface evaluation, learning curve assessment

Real-world example: Koios required rigorous evaluation for 300 students across different time zones. I applied Nielsen Norman's heuristics (1, 5) systematically and developed remote user testing frameworks that could work at scale. The desirability testing revealed that students valued the "distraction-free" learning environment — emotional language that guided the full-screen interface design.

Creative & Generative Methods

These methods help you generate new ideas and explore possibilities.

Method	What Fascinates Me	Why I Use It	When to Use It
Brainwriting (6-3-5)	The silent, structured approach levels the playing field (4). Introverts get equal voice, and the building on others' ideas creates unexpected connections.	Gives everyone a voice, works especially well in hybrid settings	Inclusive ideation, introvert-friendly sessions
SCAMPER	The systematic approach to creativity is fascinating (4). By applying specific transformations (Substitute, Combine, Adapt, etc.), you can transform any idea into something new.	Recontextualize concepts by applying them to other contexts, spark new directions	Overcoming creative blocks, idea generation
Business Origami	The physical prototyping of service interactions makes abstract concepts tangible (4). Watching stakeholders move paper around reveals the complexity of service ecosystems.	Prototype interaction and value exchange among people, artifacts, and environments	Service design, stakeholder mapping, system visualization
Collage	The visual metaphors people choose reveal their subconscious associations (4). A picture of a mountain might represent "challenge" or "achievement" — the interpretation is always revealing.	Allow participants to project thoughts, feelings, and desires onto visual artifacts	Understanding emotional associations, creative expression
Sensorial Brainstorm	Most brainstorming focuses on visual solutions. By explicitly considering all five senses, you unlock completely different types of ideas (4).	Trigger innovative solutions by thinking beyond visual, auditory, and tactile solutions	Sensory design, innovative ideation

Real-world example: PetsetLife used cultural probes in the form of "pet-sitting cards" — creative artifacts that allowed users to express their availability and preferences visually. This approach revealed deeper insights about trust and authenticity than traditional forms could capture. The brainwriting process (4) helped our small team generate ideas without the pressure of vocal brainstorming sessions.

Analysis & Synthesis Methods

These methods help you make sense of research data and find patterns.

Method	What Fascinates Me	Why I Use It	When to Use It
Affinity Diagramming	The bottom-up clustering process is magical (5). Starting with individual observations and watching themes emerge organically feels like discovering hidden patterns in the data.	Cluster insights from research, find people's stories, needs, and tasks	Research synthesis, pattern identification
Evaluation Box (COCD)	The visual matrix makes complex decisions tangible (4). Seeing ideas plotted by originality vs. feasibility helps teams make informed choices without getting stuck in analysis paralysis.	Select most promising ideas from brainstorm with less constraints from feasibility	Idea evaluation, stakeholder alignment
KJ Technique	The silent prioritization process eliminates groupthink (4). When people can't see others' votes, they make more honest choices based on their own judgment.	Define priorities in groups when stuck or lacking consensus	Group prioritization, consensus building
Laddering	The "why" questions reveal the deeper values that drive behavior (5). What starts as a preference for a specific feature often leads to fundamental human needs and motivations.	Reveal connections between product characteristics and deeper personal values	Understanding motivations, value hierarchy

Real-world example: SmoothRide used affinity diagramming (5) to cluster citizen feedback about infrastructure. The bottom-up approach revealed that people weren't just reporting problems — they were sharing experiences and ideas. This insight transformed the platform from a complaint system into a collaborative ideation tool, showing how synthesis methods can reframe entire problem spaces.

Specialized Methods

These methods address specific challenges or contexts.

Method	What Fascinates Me	Why I Use It	When to Use It
Wizard of Oz	The illusion of a working system is powerful (5, 7). Users behave differently when they think they're interacting with real technology, revealing insights about future interactions.	Simulate system responses from behind the scenes while participants engage with apparently real system	Testing complex interactions, prototyping AI systems
Speed Dating	The rapid iteration with multiple concepts reveals preferences quickly (4). It's like speed dating with ideas instead of people — you quickly learn what resonates.	Rapidly "speed date" design opportunities with potential users	Concept validation, rapid iteration
Experience Sampling Method	The real-time nature captures authentic moments (5). Getting insights when people are actually experiencing something provides a different quality of data than retrospective accounts.	Collect snapshots of behaviors, interactions, thoughts, or feelings on demand	Real-time insights, behavioral capture
Crowdsourcing	The "strength of weak ties" is fascinating (5). People you don't know personally often provide the most honest and diverse feedback.	Leverage large groups to complete tasks and microprojects	Large-scale feedback, diverse perspectives

Real-world example: In the first iteration of SmoothRide, I implemented a Wizard of Oz approach (5, 7) with AI-generated infrastructure recommendations using Quant UX. Users interacted with what appeared to be an intelligent system, but behind the scenes, I was learning about their preferences and needs in regards to the used OpenAI model. This method revealed that citizens wanted inspiration, not just reporting tools — insights that shaped the entire platform direction.

Bonus Methods for Creativity

Sometimes the best ideas come when you step outside the usual frameworks. These creative methods help me open up, involve others, and bring more humanity into the process — especially in early ideation or stakeholder sessions.

Method	What Fascinates Me	Why I Use It	Best For
Love Letter / Breakup Letter	The emotional vulnerability this method creates is powerful (4). When people write to products as if they're relationships, they reveal pain points that structured interviews never touch.	Raw, honest emotional insight — helps humanize pain points	Understanding emotional relationships with products
Brainwriting (6-3-5)	The silent, structured approach levels the playing field (4). Introverts get equal voice, and the building on others' ideas creates unexpected connections.	Gives everyone a voice — works especially well in hybrid settings	Inclusive ideation, introvert-friendly sessions
Evaluation Box (COCD)	The visual matrix makes complex decisions tangible (4). Seeing ideas plotted by originality vs. feasibility helps teams make informed choices without getting stuck in analysis paralysis.	Helps prioritize ideas without shutting them down prematurely	Idea evaluation, stakeholder alignment

How to Use These Heuristics

These aren't just checklists — they're lenses for seeing your design work differently. Here's how I approach them:

Start with the problem: Which factors are most relevant to your specific challenge?
Mix and match: Combine different heuristics to get a complete picture
Ask the questions: Use the evaluation questions to guide your thinking
Look for patterns: What factors are consistently weak or strong?
Prioritize ruthlessly: Not every factor matters equally for every project

Remember: these heuristics are tools for thinking, not rules for following. Use them to ask better questions, not to find the "right" answers.

What Fascinates Me About These Methods

The thing that keeps me coming back to these methods is how they reveal the gap between what we think we know and what's actually happening. Each method is like a different lens on the same problem:

Discovery methods show us what we're missing
Evaluation methods show us what we got wrong
Creative methods show us what we haven't considered
Analysis methods show us patterns we couldn't see

The best research isn't about confirming our assumptions — it's about discovering our blind spots. These methods help us see the world through our users' eyes, not just our own.

This practical guide complements my philosophical exploration of why fundamentals matter more than tools. Together, they form a complete approach to thoughtful, human-centered design.

Real-world example: Flasq demonstrates how emotional design drives engagement. Users reported feeling like the device was a "mystical companion" they didn't want to let down. This emotional connection proved more effective than traditional hydration reminders, showing how narrative and authenticity can transform mundane interactions into meaningful experiences.
