Mental Model Mapping 🧭 Prompts

SUMMARY

Purpose: Mental Model Mapping helps UX teams understand how users think about a system, task, or concept so designs align with users' expectations and mental organisation.

Design Thinking Phase: Define

Time: 45–60 min session + 1–2 hours analysis

Difficulty: ⭐⭐

When to use:When shaping IA or onboarding flows based on user logicTo identify mismatches between system behaviour and user expectationsWhen redesigning features based on cognitive gaps uncovered in usability testing

What it is

Mental Model Mapping is a qualitative research method used to visualise how users perceive and mentally organise tasks, goals, and systems. It captures users’ thought processes through interviews or observational data and maps these to highlight overlaps and gaps between user models and system models.

Why it matters

Product success hinges on how well your solution fits the way users think and behave. Mental Model Mapping creates a visual comparison between current product design and how users expect it to behave or be structured. It brings clarity to redesign decisions, uncovers hidden friction points, and gives the design team the confidence that they’re addressing real, not assumed, misalignments.

When to use

• Before restructuring navigation or IA to reflect user logic
• To guide prioritisation of feature improvements in early-stage roadmap planning
• Post usability testing, to dig deeper into unexpected user errors or slowdowns

Benefits

• Rich Insights: Helps uncover user needs that aren’t visible in metrics.
• Flexibility: Works across various project types and timelines.
• User Empathy: Deepens understanding of behaviours and motivations.

How to use it

1. Conduct open-ended user interviews using task-based framing (e.g. “Walk me through how you do X”).

2. Note explicit actions as well as mental triggers, assumptions, tools used, and emotional checkpoints in each story.

3. Cluster statements into conceptually similar groupings to reflect users' internal thinking structure.

4. Map these groupings as a vertical user model stack — task flow layered with insights, thoughts, and motivators.

5. Overlay your current system model horizontally to visually highlight gaps and alignment.

6. Analyse mismatched areas to generate design opportunities or refinement points.

Example Output

Fictional Example: A financial wellness app team maps future saving behaviour for Gen Z users.

• User model includes: “Worry about bills → Google saving hacks → Look for TikTok finance tips → Use banking app to set goal reminder.”
• System model jump-starts with: “Open app → Navigate to goals tab → Pre-fill income & saving ratio → Suggest goal.”
• Gap: Users require trusted advice before even considering savings, while app assumes users initiate savings without needing confidence-building or guidance.

Common Pitfalls

• Insufficient data: Mapping on too few interviews creates weak or misleading patterns. Aim for at least 8–10 varied sessions.
• Assuming linear thinking: Mental models aren't always logical task flows. Look for intent and triggers, not only sequence.
• Polishing too early: Jumping to design based on partial mental maps undercuts this method's real value — system-user misalignment diagnosis.

How These Prompts Work (C.S.I.R. Framework)

Each of the templates below follows the C.S.I.R. method — a proven structure for writing clear, effective prompts that get better results from ChatGPT, Claude, Copilot, or any other LLM.

C.S.I.R. stands for:

• Context: Who you are and the UX situation you're working in
• Specific Info: Key design inputs, tasks, or constraints the AI should consider
• Intent: What you want the AI to help you achieve
• Response Format: The structure or format you want the AI to return (e.g. checklist, table, journey map)

Prompt Template 1: “Draft a User Mental Model from Raw Interview Data”

Draft a User Mental Model from Raw Interview Data

Context: You are a UX researcher organising qualitative interview notes into a usable mental model.
Specific Info: Interview transcripts describe how [users plan trips using multiple travel tools], including [brands/tools mentioned] and [point of frustration].
Intent: Create a layered mental model illustrating user thought flow, decision cues, and emotional anchors.
Response Format: Provide a structured mental model diagram (text-based), grouped by themes, actions, and emotional stages.

If the emotional stages or tools are unclear, ask clarifying questions before responding.
Suggest a next step, like validating the model with another user type.
