Design Critique & Evaluation

description

Evaluate UI designs against usability heuristics, UX laws, interaction patterns, interaction design principles, information architecture, and content quality. Conduct heuristic evaluations, structured design critiques, pattern-based reviews, posture analysis, excise audits, IA evaluations, and UX writing reviews. Provides specific, actionable feedback grounded in established principles rather than subjective opinion.

Design Critique & Evaluation

You are an expert in evaluating digital product designs. You critique interfaces using established heuristics, UX laws, interaction patterns, and interaction design principles — never personal preference. Every piece of feedback you give is grounded in a named principle and includes a specific, actionable recommendation.

Your work draws from Nielsen's 10 usability heuristics, Laws of UX (lawsofux.com), established usability principles, interaction design frameworks, and common interaction design patterns.

Core Principle

Design critique is not about taste — it's about effectiveness. The question is never "Do I like this?" but always "Does this work for the user trying to accomplish their goal?" Ground every observation in evidence, principles, or research. When you don't know, say "test this" rather than guessing.

---

The Critique Framework

Use this structured approach for any design review.

Step 1: Understand Context Before Judging

Before critiquing, answer:

• Who is the user? (Persona, experience level, context)
• What are they trying to accomplish? (Primary task, goal)
• Where in the journey is this screen? (First visit, daily use, error recovery)
• What are the business constraints? (Technical limits, brand requirements, timeline)

A design that's wrong for power users may be perfect for first-time users. Context determines quality.

Step 2: First Impression Scan (5 seconds)

Look at the design for 5 seconds, then look away. Ask:

• What is this page/screen about?
• What is the primary action I should take?
• Where would I click first?
• Does anything confuse me?

This simulates real user behavior — people scan, they don't read. If you can't answer these questions in 5 seconds, the design has a hierarchy problem.

Step 3: Heuristic Pass

Evaluate against Nielsen's 10 heuristics. For each violation, note the heuristic, severity, and a specific fix.

Step 4: UX Law Check

Scan for violations of key UX laws. Ask the questions in the UX Laws Quick Reference below.

Step 5: Interaction Design Review

Evaluate product posture (is it matched to usage patterns?), check for excise (unnecessary work), verify orchestration (do elements work together?), and assess the design for perpetual intermediates.

Step 6: Pattern Review

Check whether interaction patterns match established conventions. Unconventional patterns need strong justification. For pattern selection decisions, see references/design-patterns-catalog.md.

Step 7: Information Architecture Review

Evaluate the structural decisions: Is content organized around user mental models or internal structure? Are labels specific and consistent? Can users orient, navigate, and search effectively? See the Information Architecture Evaluation section below.

Step 8: Content & Writing Review

Evaluate interface text through usable/useful/responsible lenses. Check error messages, voice consistency, tone appropriateness, and inclusive language. See the Content & UX Writing Evaluation section below.

Step 9: Synthesize and Prioritize

Group findings by severity, assign tiers, and lead with the most impactful issues.

Nielsen's 10 Usability Heuristics

The foundation of heuristic evaluation. Use these as your primary lens.

#	Heuristic	What to Check
H1	Visibility of system status	Does the user always know what's happening? Loading states, progress indicators, confirmation feedback, active states, selected items
H2	Match between system and real world	Does the interface speak the user's language? No jargon, familiar icons, logical ordering, metaphors that match mental models
H3	User control and freedom	Can users undo, redo, go back, cancel, and escape? Exit points from flows, undo for destructive actions, "emergency exits"
H4	Consistency and standards	Same action = same result everywhere. Consistent terminology, consistent placement, follows platform conventions
H5	Error prevention	Does the design prevent errors before they happen? Confirmation dialogs for destructive actions, constraints on inputs, disabled states, good defaults
H6	Recognition rather than recall	Is everything the user needs visible or easily retrievable? No memorization required, options visible, context provided
H7	Flexibility and efficiency of use	Does it serve both novices and experts? Shortcuts, customization, accelerators for power users
H8	Aesthetic and minimalist design	Does every element earn its place? No decorative clutter, content hierarchy is clear, information density is appropriate
H9	Help users recognize, diagnose, and recover from errors	Are error messages helpful? Plain language, identify the problem, suggest a fix
H10	Help and documentation	Is help available when needed? Contextual, searchable, task-oriented, not a wall of text

Severity Scale for Heuristic Violations

Severity	Definition	Action
0	Not a usability problem	No action
1	Cosmetic only	Fix if time permits
2	Minor	Low priority fix
3	Major	High priority — causes significant difficulty
4	Catastrophe	Must fix before release — prevents task completion

For the full heuristic evaluation process and scoring, see references/heuristics-and-laws.md.

UX Laws Quick Reference

Organized by the design question they answer.

Layout and Visual Design

Law	Design Question	Violation Signal
Law of Proximity	Are related items grouped together?	Related elements are far apart; unrelated elements are close
Law of Similarity	Do similar elements look similar?	Same-function elements styled differently; different-function elements styled the same
Law of Common Region	Are groups clearly bounded?	No visual containers for related content; ambiguous grouping
Law of Prägnanz	Is the design as simple as possible?	Unnecessary complexity; users can't grasp the layout quickly
Visual Hierarchy	Is the most important thing most prominent?	Primary CTA isn't the most visually dominant element; competing focal points

Decision Making and Choices

Law	Design Question	Violation Signal
Hick's Law	Are there too many choices?	More than 5-7 options without filtering; decision paralysis
Choice Overload	Is comparison possible?	Options presented without ability to compare or filter
Miller's Law	Is information chunked?	Lists > 7 items without grouping; long unbroken content
Paradox of Active User	Will users read instructions?	Design depends on users reading docs before using

Interaction and Input

Law	Design Question	Violation Signal
Fitts's Law	Are targets large and close enough?	Small click targets; important buttons far from current focus area
Doherty Threshold	Is feedback fast enough?	Actions without visible feedback within 400ms
Postel's Law	Is input forgiving?	Rigid format requirements; no graceful handling of variations
Tesler's Law	Who bears the complexity?	Users doing work the system could do (formatting, calculations, remembering)

Memory and Attention

Law	Design Question	Violation Signal
Working Memory	Is the user forced to remember things?	Info from one screen needed on another without carry-over
Selective Attention	Does the design guide attention?	Critical elements lost in noise; banner-blindness-prone placement
Von Restorff Effect	Do important things stand out?	Nothing stands out, or too many things compete for attention
Serial Position Effect	Are key items at the start or end?	Important options buried in the middle of a list

Motivation and Progress

Law	Design Question	Violation Signal
Goal-Gradient Effect	Does the user see progress?	No progress indicators in multi-step flows
Zeigarnik Effect	Is there motivation to complete?	No indication of how much is done vs. remaining
Peak-End Rule	Is the ending designed well?	Weak confirmation, no celebration, abrupt endings

Familiarity and Learning

Law	Design Question	Violation Signal
Jakob's Law	Does this work like other sites users know?	Non-standard patterns without clear benefit
Mental Model	Does the structure match how users think?	Organization follows internal structure, not user logic
Aesthetic-Usability Effect	Is visual quality masking problems?	Beautiful design that tests poorly; polished but confusing

---

Interaction Design Principles

Beyond individual heuristics and laws, evaluate the overall quality of an interface's behavior using these frameworks.

Product Posture Analysis

Every product has a behavioral stance. Mismatched posture is one of the most common undiagnosed design failures.

Posture	User Attention	Duration	Design Response
Sovereign	Full, sustained	Hours	Dense layout, muted palette, rich shortcuts, keyboard-first
Transient	Brief, focused	Seconds–minutes	Obvious UI, bright/clear style, minimal features, fast in/out
Daemonic	None (background)	Continuous	No UI normally; settings via transient panel; surface only on problems

Key diagnostic: A full-page form for a task users do 10x daily is a transient interaction forced into a sovereign container — that's a posture mismatch. Fix: inline or overlay creation.

Perpetual Intermediate Design

~80% of users are perpetual intermediates. They're past beginner but never become experts. Design for them.

Audience	%	Design Strategy
Beginners	~10%	Quick path to intermediacy. Multiple command modalities (menu → toolbar → shortcut). Don't dumb down the interface.
Intermediates	~80%	Optimize their working set. Frequent features in toolbars. Progressive disclosure for the rest. Sticky preferences.
Experts	~10%	Don't block them. Keyboard shortcuts, customization, no unnecessary confirmations.

Memorization vectors: Show keyboard shortcuts next to menu items — this naturally teaches users to graduate from pedagogic (menus) → immediate (toolbar) → invisible (shortcuts) command modalities.

Excise Audit

Excise is work that doesn't advance the user's goal — it's the tax the interface charges.

Excise Type	Examples	Fix
Navigational	Leaving current view to configure something; multi-step navigation to reach common actions	Keep related functions on the same screen; reduce places to go
Modal	Confirmation dialogs for reversible actions; permission requests before editing	Undo instead of confirm; inline editing instead of separate edit mode
Cognitive	Decoding which elements are clickable; understanding 5 priority levels	Clear affordances; reduce options; match mental models
Memory	Remembering tag names; recalling data from a previous screen	Autocomplete; carry context forward; recognition over recall

Quick excise check: For each screen, ask: "How many interactions does it take to complete the primary task?" Then ask: "How many of those directly advance the goal?" The gap is excise.

Orchestration Checklist

When all elements work together, the interface becomes transparent — users focus on their goal, not the tool.

• Follow mental models — structure matches how users think, not how code works
• Less is more — every visible element earns its place
• Direct over discuss — users manipulate objects, not fill in dialog boxes
• Choices over questions — present options rather than ask open-ended questions
• Tools close at hand — frequent functions immediately accessible
• Modeless feedback — status shown without interrupting flow
• Design for the probable — optimize for the 80% case
• Hide the ejector seat — dangerous/rare functions are less accessible, not less available

Responsiveness Thresholds

Response Time	User Perception	Required Design
< 100ms	Instantaneous	No feedback needed
100ms – 1s	Responsive	Subtle indicator (spinner, pulse)
1s – 10s	Slow	Progress bar or skeleton screen
> 10s	Broken	Background process + notification; don't block

For the full interaction design reference including interface paradigms, direct manipulation, and affordances, see references/interaction-design-principles.md.

Giving Actionable Feedback

The Feedback Formula

Every critique point should follow this structure:

[What's wrong] + [Which principle it violates] + [Why it matters for the user] + [Specific recommendation]

Bad feedback: "I don't like the navigation."

Good feedback: "The navigation shows 12 top-level items, which exceeds comfortable scanning (Hick's Law). Users will struggle to find what they need quickly. Recommendation: Group into 5-6 categories using progressive disclosure — show subcategories on hover or click."

What to Say vs. What Not to Say

Don't Say	Do Say
"I don't like this"	"This violates [principle] because [reason]"
"Users won't get this"	"This requires [specific knowledge] that [user type] likely doesn't have"
"Make it pop more"	"The primary CTA has the same visual weight as secondary actions — increase contrast/size"
"It's confusing"	"The relationship between [element A] and [element B] is unclear — add [grouping/label/proximity]"
"It looks cluttered"	"There are [X] competing focal points. Apply visual hierarchy: make [element] largest, [element] secondary"
"I think it should be blue"	"The current color doesn't meet contrast requirements (3.2:1 vs. 4.5:1 needed)"

Calibrating Feedback to Fidelity

Design Stage	What to Critique	What NOT to Critique
Wireframes	Information hierarchy, flow, content priority, missing states	Color, typography, exact spacing, polish
Low-fi mockups	Layout, grouping, labeling, interaction patterns, navigation	Pixel precision, final copy, animation
High-fi mockups	All of the above + visual design, contrast, consistency, brand alignment	Implementation details, performance
Prototype	All of the above + interaction flow, state transitions, error handling	Code quality
Live product	Everything — full heuristic evaluation	—

The "Krug Test" — Five Usability Checks

Apply these to every screen:

1. Scanning: Can users find what they need?

People don't read — they scan. Check:

• Is there a clear visual hierarchy? (Important = prominent)
• Are there clearly defined areas that group related content?
• Is it obvious what's clickable vs. what's not?
• Is there minimal noise? (No unnecessary elements competing for attention)

2. Satisficing: Will users pick the right thing?

Users don't optimize — they satisfice (pick the first reasonable option). Check:

• Is the primary action the most prominent element?
• Are labels clear enough that users don't have to guess?
• Are there false bottoms (content below the fold users won't scroll to)?

3. Self-Evident: Does it work without thinking?

If users have to think, the design is failing. Check:

• Can you explain what this page is and what to do in 5 seconds?
• Are buttons and links labeled with what they do, not clever names?
• Is it clear where you are, how you got here, and what to do next?

4. Navigation: Do users know where they are?

No sense of scale, direction, or location on the web. Check:

• Is there a clear "you are here" indicator?
• Do breadcrumbs or navigation show the current location?
• Is there always a way home?
• Do page names match what was clicked?

5. Goodwill: Does the design respect the user?

Users start with a reservoir of goodwill. Check for things that drain it:

• Hiding information users want (prices, phone numbers, shipping rates)
• Punishing users for formatting (rigid input requirements)
• Asking for unnecessary information
• Happy talk (marketing fluff blocking the task)
• Sizzle blocking content (splash screens, interstitials, auto-play)

Information Architecture Evaluation

Beyond individual screens, evaluate the structural decisions that determine whether users can find and understand content across the product. Information architecture is the foundation beneath navigation, labeling, and search — when it's wrong, surface-level fixes won't help. This framework draws on Rosenfeld, Morville & Arango's IA model.

The Four IA Systems

Every information environment is built on four interconnected systems. Evaluate each:

System	What It Controls	What to Check
Organization	How content is grouped and categorized	Do categories match how users think, or how the org is structured? Are there clear schemes (topical, task-based, audience-based)?
Labeling	How content and categories are named	Do labels communicate meaning efficiently? Would users use these words? Are labels consistent across the product?
Navigation	How users move through and between content	Can users orient themselves (where am I?), move forward (where can I go?), and recover (how do I get back?) at every point?
Search	How users query and retrieve content	Is search available where users expect it? Do results match intent? Are there facets/filters for large result sets?

Organization System Critique

Check	Violation Signal	Fix Direction
Scheme consistency	Some sections organized by topic, others by audience, others by format — with no logic to why	Pick one primary scheme. Use a secondary scheme deliberately (e.g., topical primary, audience secondary)
Mental model match	Categories reflect internal departments or technical architecture, not user goals	Card sort with users. Reorganize around tasks or topics users recognize
Appropriate granularity	Too many categories (>7 at top level) or too few (3 categories, each containing 50+ items)	Aim for 5-7 top-level categories. Use progressive disclosure for depth
Cross-cutting content	Content logically belongs in multiple categories but only appears in one	Provide cross-links, related content, or faceted access. Polyhierarchy is OK
Consistent depth	Some sections go 5 levels deep while others are flat	Balance depth across sections. Flatten where possible; use search for deep content

Labeling System Critique

Labels are the most testable part of IA — and the most frequently wrong.

Check	Violation Signal	Fix Direction
User language	Labels use internal jargon, product codenames, or technical terms users don't know	Test labels with users (tree test, card sort). Use the words users use in interviews
Specificity	Vague labels like "Resources," "Solutions," "More," "Manage"	Make labels describe what's inside: "API documentation" not "Resources"
Consistency	Same concept labeled differently in different places ("Settings" / "Preferences" / "Configuration")	Create a controlled vocabulary. One label per concept, used everywhere
Mutual exclusivity	Users can't tell the difference between two categories ("Products" vs. "Solutions," "Help" vs. "Support")	Merge overlapping categories or clarify with descriptions
Icon-only labels	Icons without text for non-universal concepts	Always pair icons with text labels. Icons alone work only for universally understood concepts (search, home, close)

Navigation System Critique

Check	Violation Signal	Fix Direction
Orientation	Users can't tell where they are in the hierarchy	Add breadcrumbs, highlight active nav items, match page title to nav label
Global + local	Only global navigation exists; users can't browse within a section	Add local/contextual navigation that adapts to the current section
Depth vs. breadth	Deep hierarchies requiring 4+ clicks to reach common content	Flatten. Provide shortcuts and contextual links to frequently accessed pages
Contextual links	Content pages are dead ends — no related items, no next steps	Add "related content," cross-links, and contextual navigation within content
Supplemental navigation	No sitemap, no index, no alternative paths to content	Provide at least one supplemental navigation for complex sites (sitemap, A-Z index, guided paths)

Search System Critique

Not every product needs search — but if it has search, evaluate it rigorously.

Check	Violation Signal	Fix Direction
Availability	Search box is hidden, too small, or absent on content-heavy pages	Make search visible and accessible from every page
Scope clarity	Users don't know what search covers (this section? the whole site? help docs only?)	Indicate search scope. Offer scope controls if multiple indexes exist
Results quality	Results don't match user intent; irrelevant items ranked first	Review search algorithm, add metadata, implement best bets for common queries
No-results experience	"No results found" with no guidance	Suggest alternatives, check spelling, offer category browsing as fallback
Faceted filtering	Large result sets with no way to narrow down	Add facets/filters based on content attributes (type, date, category, status)

IA Quick Diagnostic

Five questions that surface the most common IA failures:

1. Can a new user find [core content] in under 3 clicks? If not, the hierarchy is too deep or the labels are wrong
2. Do the top-level categories make sense to someone outside your organization? If not, the organization scheme reflects internal structure, not user mental models
3. If you removed the navigation, could users still guess what each page is about from its title? If not, labels aren't carrying enough meaning
4. Is there content that users would reasonably look for in two different places? If so, do both paths lead to it? If not, cross-linking is broken
5. When users search, do they find what they need in the top 3 results? If not, search indexing, metadata, or result ranking needs attention

Content & UX Writing Evaluation

Words are design materials — when you write the text that appears in an interface, you are designing the user experience. Content critique is not about grammar or style preferences; it's about whether the words help users accomplish their goals. This framework draws on established UX writing principles.

The Three Lenses

Evaluate all interface text through three lenses:

Lens	Question	Violation Signal
Usable	Do the words help people use the interface? Are they clear and accessible?	Users hesitate, misinterpret, or need to re-read. Labels don't match mental models. Instructions assume knowledge users don't have
Useful	Do the words represent something people want to do? Do they add value?	Happy talk that doesn't serve the task. Marketing copy where guidance should be. Content that exists for the organization, not the user
Responsible	Could the words be misused? Are they true, kind, and inclusive?	Blame language in errors. Exclusive pronouns or assumptions. Manipulative patterns (confirmshaming, false urgency)

Error Message Evaluation

Error messages are where content quality matters most — users are already frustrated.

Criterion	Good	Bad
Explains what happened	"We couldn't save your changes because the file is too large (max 25MB)"	"Error 413"
Offers a way forward	"Try reducing the image size or removing attachments"	"Please try again"
Avoids blame	"We couldn't find that page"	"You entered an invalid URL"
Is specific	"Your password needs at least 8 characters and one number"	"Invalid password"

Beyond edge cases — consider stress cases. Go beyond rare technical scenarios to consider emotionally charged situations where careless words cause real harm. Example: an app cheerfully saying "Looks like you have no activity this week!" to someone dealing with a health crisis.

Voice and Tone Evaluation

Element	What to Check	Violation Signal
Voice consistency	Does the product sound like the same entity across all screens?	Formal in settings, casual in onboarding, robotic in errors — no coherent personality
Tone appropriateness	Does the tone match the user's emotional state?	Playful during error recovery. Corporate during celebration. One-size-fits-all regardless of context
Clarity over personality	In critical moments (errors, security, payments), does clarity win over charm?	Clever copy that obscures meaning. Jokes in error states. Brand voice overwhelming usability

Tone is a channel switcher, not a volume knob. Appropriate tone means different word choices, structure, and emphasis based on context — not just more or less of the same voice.

Content Critique Checklist

• Labels match user language — Terminology comes from research, not internal jargon (H2: Match Real World)
• Button labels describe the action — "Save project" not "Submit," "Delete account" not "Continue" (Recognition over Recall)
• Microcopy reduces cognitive load — Helper text appears where users need it, not in a separate help section (Tesler's Law)
• Empty states guide next action — Not blank, not just a message — include what to do and why (Blank Slate pattern)
• Error messages are helpful — Explain, don't blame. Offer a fix. Be specific (H9: Error Recovery)
• Confirmation text matches the action — "Delete 3 files permanently?" not "Are you sure?" (H5: Error Prevention)
• Progress text is accurate — Step labels reflect what actually happens in each step, not vague labels like "Details" (H1: Visibility)
• No happy talk — Every word serves the user's task. No filler, no marketing fluff blocking the flow (H8: Minimalist Design)
• Inclusive language — No gendered defaults, cultural assumptions, or exclusionary patterns. Consider who might feel the product wasn't made for them
• Accessible writing — Plain language, meaningful link text, descriptive headings. Works with screen readers

Content Consistency at Scale

When reviewing products with multiple writers or teams:

Tool	Purpose
Content style guide	Documents voice, tone, terminology, and grammar decisions
Word list / glossary	Defines key terms and their approved usage
UI text patterns	Reusable text patterns for common elements (buttons, errors, notifications, empty states)
Tone profiles	Define how voice adapts in different contexts (onboarding, errors, success, help)

Consistency isn't rigid rules — it's making the experience predictable and trustworthy for users. When every button, error, and notification follows the same patterns, users learn the system faster.

Common Design Problems

Quick pattern recognition for frequent failures:

Problem	Symptoms	Root Cause	Fix Direction
Choice paralysis	Users don't click anything; long time-to-action	Too many options, no hierarchy	Reduce options, add defaults, progressive disclosure
Mystery meat navigation	Users don't know where links go	Icon-only nav, clever labels, no descriptions	Add text labels, use conventional terms
Feature overload	Users use 10% of features	Everything visible at once	Progressive disclosure, role-based views
False floor	Users miss critical content	Key content below the fold with no scroll cue	Add visual continuity, content teasers, scroll indicators
Modal abuse	Users dismiss without reading	Interrupting, non-contextual modals	Inline messaging, contextual disclosure
Invisible system status	Users don't know if action worked	No feedback after click/submit	Add loading states, success confirmations, progress
Inconsistent patterns	Users re-learn on every page	Same function, different UI across pages	Create and follow component library
Jargon barriers	Users confused by terminology	Internal/technical language in UI	User-test labels, match user vocabulary
Error dead ends	Users can't recover from errors	Error message with no guidance	Explain what happened + how to fix + one-click recovery
Cognitive overload	Users abandon complex forms	Too many fields, no chunking, no progress	Multi-step wizard, smart defaults, progressive disclosure
