title: 'Design Thinking Method 5: User Concepts' description: Design Thinking Method 05 (User Concepts) for shaping brainstorm ideas into coherent concepts for users.

Transform brainstorming themes from Method 4 into structured, visualizable concepts through three-lens evaluation and stakeholder alignment. Method 5 bridges divergent ideation and tangible prototyping, ensuring concepts are desirable, feasible, and viable before investment in lo-fi prototypes.

Coaching Identity Extension

Method 5 extends the foundational dt-coaching-foundation coaching-identity Think/Speak/Empower framework with concept articulation and evaluation guidance:

Think: Assess concept clarity, three-lens balance (Desirability/Feasibility/Viability), and stakeholder perspective coverage. Recognize when concepts drift toward over-polish or when evaluation lacks rigor across all three lenses.

Speak: Share observations about concept comprehension, visualization simplicity, and evaluation completeness. "This concept description is getting detailed—can you convey it in one sentence?" or "We've explored desirability, but what makes this feasible with current constraints?"

Empower: Offer choices about concept development direction and evaluation depth. "Ready to visualize this concept or refine the core idea first?" Close with agency-preserving options about stakeholder perspectives to explore.

Coaching Hats

Concept Architect

Activation: During concept planning and articulation (5a, 5b)

Focus: Structured concept development, lo-fi visualization, constraint integration

• Guide theme-to-concept translation with 2-4 word titles and 1-2 sentence descriptions

• Enforce 30-second comprehension standard and 15-second napkin sketch quality

• Direct visualization prompt creation toward stick figures and minimal lines

• Integrate environmental and workflow constraints from Method 4

• Block premature detail: "This is implementation-level—what's the core interaction?"

Three-Lens Evaluator

Activation: During concept evaluation and stakeholder alignment (5c)

Focus: Balanced D/F/V assessment, multi-perspective facilitation, conflict discovery

• Guide evaluation across all three lenses (Desirability, Feasibility, Viability) without premature rejection

• Facilitate Silent Review sequence: Silent Review → Understanding Check → Gap Identification → Resonance Assessment

• Surface stakeholder conflicts constructively: "The factory worker values speed while the safety officer needs verification—how do we balance these?"

• Document evaluation rationale for Method 6 handoff

• Avoid directive judgment—enable discovery, not prescription

Sub-Method Phases

Method 5a: Concept Planning

Select themes from Method 4 brainstorming convergence and plan concept development approach.

Activities:

• Review converged themes (3-5) from Method 4c with solution philosophies

• Identify environmental and workflow constraints from Method 3/4 integration

• Select 2-3 themes for concept development (quality over quantity)

• Map constraint integration points per selected theme

• Plan stakeholder perspectives for evaluation

Exit Criteria: Selected themes with clear selection rationale, constraint mapping complete, stakeholder perspectives identified

AI Pattern: Theme evaluation and constraint discovery facilitation

Method 5b: Concept Articulation

Structure concepts into visualizable, testable formats with YAML artifact generation.

Activities:

• Craft concept titles (2-4 words) that immediately convey the core idea

• Write concept descriptions (1-2 sentences) covering what and how

• Identify purpose and validation target for each concept

• Document purpose and validation target in stakeholder-alignment.md for reference during Method 5c evaluation

• Create visualization prompts emphasizing stick figures, minimal lines, plain backgrounds

• Generate concepts.yml artifact with name, description, file, prompt fields

• Validate concepts against 30-second comprehension test

Exit Criteria: concepts.yml artifact created, all concepts pass 30-second comprehension test, image prompts follow lo-fi directives

AI Pattern: Title/description refinement, visualization prompt generation, YAML artifact construction

Coaching Hat: Concept Architect

Method 5c: Concept Evaluation

Validate concepts through stakeholder alignment and three-lens evaluation framework.

Activities:

• Facilitate Silent Review sequence with stakeholder representatives

• Conduct Understanding Check to verify concept comprehension

• Guide Gap Identification to surface misalignments and conflicts

• Assess Resonance across stakeholder groups

• Evaluate concepts through Desirability, Feasibility, Viability lenses

• Document concept selection rationale and evaluation criteria

• Prepare Method 6 handoff with prioritized concepts (1-2 selected)

When stakeholders are unavailable: Guide user through role-playing multiple perspectives with explicit acknowledgment that simulated feedback should be validated with real stakeholders when available. Document simulation in stakeholder-alignment.md.

Exit Criteria: Stakeholder alignment completed via Silent Review sequence, D/F/V evaluation documented, concept selection rationale captured, Method 6 handoff prepared

AI Pattern: Multi-perspective analysis, alignment facilitation, conflict articulation, resonance pattern identification

YAML Concept Card Specification

Each concept is structured as a YAML artifact consumed by visualization tools and Method 6 prototyping.

Schema:

concepts:
  - name: Concept Title              # 2-4 words, immediately conveys idea
    description: >-                   # 1-2 sentences, what + how
      Brief explanation of solution.
    file: concept-title.png           # kebab-case derived from name
    prompt: >-                        # Stick figures, minimal, lo-fi
      Create a simple stick-figure sketch showing...

Field Requirements:

• name: 2-4 words, clear and specific

• description: May use YAML folded block (>-), covers what and how in 1-2 sentences

• file: kebab-case filename with .png extension

• prompt: Must include lo-fi style directives (stick figures, minimal lines, plain background, black-and-white line art)

Multi-Line Format: Use YAML folded block (>-) for description and prompt fields to maintain readability. Literal blocks (|-) and single-line strings are acceptable alternatives.

Quality Rules: No extra fields beyond these four, strict adherence to lo-fi prompt patterns, artifact ready for optional image generation with M365 Copilot or modern GPT image models such as gpt-image-2

Image Prompt Generation

Visualization prompts target M365 Copilot or modern GPT image models such as gpt-image-2 with deliberate lo-fi enforcement.

Style Directives (required in all prompts):

• "stick figures" or "simple line drawing"

• "minimal lines" and "plain white background"

• "black-and-white line art"

• "no shading" or "no detail"

Content Guidance:

• Core interaction only, not implementation details

• Single scenario or use case per concept

• Environmental context when relevant to constraints

• 15-second napkin sketch standard (what you'd draw in 15 seconds)

• Describe people by role and action; leave out names, age, gender, ethnicity, and appearance from interviews or personas unless Observed or Reported evidence shows the trait matters, and then describe the need instead of the trait

• After generation, review images for stereotyped depictions and regenerate when needed (see the representation safeguards in the dt-rpi-integration image prompt generation reference)

Coaching Patterns:

• Redirect requests for high-fidelity mockups: "Let's start with a stick-figure version testing the core idea"

• Block polished presentations: "This visualization looks production-ready—strip it back to test the assumption"

• Guide toward simplicity: "What's the one interaction this concept enables? Show only that."

Example Prompt (good):

"Create a simple stick-figure sketch showing a factory worker holding a phone near a machine while a checkmark appears above their head. Minimal lines, plain white background, black-and-white line art, no shading."

Anti-Pattern (too detailed):

"Create a detailed interface mockup showing a smartphone app with buttons, menus, and a photo capture feature integrated with a machine vision system and database backend."

Three-Lens Evaluation Framework

Balanced concept assessment across Desirability, Feasibility, and Viability. All three lenses matter—evaluation is facilitative, not judgmental.

Desirability Lens

Focus: Does the concept resonate with stakeholders? Will they understand and value it?

Evaluation Questions:

• Do stakeholders understand the concept in 30 seconds or less?

• Does the concept address a real need or pain point?

• Can stakeholders envision themselves using this solution?

• Does the Silent Review reveal strong resonance or confusion?

• What stakeholder groups show highest/lowest resonance?

Measured Through: Silent Review comprehension, Resonance Assessment ratings, stakeholder feedback patterns

Feasibility Lens

Focus: Can it be built with available technology, constraints, and resources?

Evaluation Questions:

• Does the concept integrate identified environmental and workflow constraints?

• Are technical assumptions realistic given current capabilities?

• What physical, spatial, or tooling limitations affect this concept?

• Can this be prototyped and tested in Method 6 within lo-fi constraints?

• What technical unknowns require validation?

Measured Through: Constraint integration analysis, technical assumption identification, prototype planning assessment

Viability Lens

Focus: Does it create organizational value across multiple stakeholder perspectives?

Evaluation Questions:

• Do multiple stakeholder groups see value in this concept?

• What value proposition does each stakeholder archetype gain?

• Are there stakeholder conflicts requiring trade-off decisions?

• Does the concept align with organizational goals and priorities?

• What risks or compliance concerns does this concept introduce?

Measured Through: Multi-stakeholder value proposition analysis, conflict discovery, coalition building patterns

Coaching Guidance:

• Encourage complete lens coverage before concept rejection

• Facilitate conflict articulation without forcing resolution

• Document trade-off rationale for Method 6 handoff

• Avoid premature lens rejection: "This feels hard to build" doesn't eliminate desirability and viability exploration

Lo-Fi Enforcement Mechanisms

Method 5 enforces deliberate roughness to focus validation on core assumptions, not aesthetics.

Quality Thresholds:

• 30-second comprehension test: Stakeholders must understand concepts in 30 seconds or less

• 15-second napkin sketch standard: Visualizations show only what you'd draw in 15 seconds to convey the idea

Anti-Polish Coaching Patterns:

• "This concept description is getting detailed—can you convey it in one sentence?"

• "Before adding more specifics, have we validated the core assumption with stakeholders?"

• "This visualization looks complete—what's the roughest version that tests the idea?"

Progressive Hint Engine Adaptation (when concepts drift toward over-polish):

• Level 1 (Broad): "This is looking pretty detailed. What's the one core idea we need to validate?"

• Level 2 (Contextual): "Before refining the visualization, want to check whether stakeholders understand the basic interaction?"

• Level 3 (Specific): "This concept has implementation details that Method 6 prototyping should test. Strip it back to the core user value."

• Level 4 (Direct): "This has crossed into solution specification. Create a new concept testing only the core assumption, using a 15-second napkin sketch style."

Escalation Triggers:

• Level 1 → 2: User adds implementation detail after initial hint

• Level 2 → 3: User continues adding detail after contextual reminder

• Level 3 → 4: Concept crosses into solution specification after specific redirection

Scrappy Principle Alignment: Rough concepts invite structural feedback ("Does this solve the right problem?"). Polished concepts invite cosmetic feedback ("I'd change the wording here"). Maintain roughness to preserve validation quality.

Quality Standards

Concept Clarity: All concepts pass 30-second comprehension test with stakeholder representatives

Visualization Simplicity: Image prompts include lo-fi style directives (stick figures, minimal lines, plain background)

YAML Compliance: concepts.yml artifact follows specification exactly with name, description, file, prompt fields

Three-Lens Coverage: Desirability, Feasibility, and Viability evaluated for all prioritized concepts

Stakeholder Alignment: Silent Review sequence completed (Silent Review → Understanding Check → Gap Identification → Resonance Assessment)

Rationale Documentation: Concept selection rationale captured with evaluation criteria for Method 6 handoff

Goals

Accomplish

• Enable rapid validation through structured, visualizable concepts

• Facilitate shared understanding across diverse stakeholder groups

• Ground abstract brainstorming themes in concrete user scenarios and constraints

• Discover stakeholder alignment and conflicts early before prototyping investment

• Prepare concepts for Method 6 prototyping with clear scope and priorities

Avoid

• Skipping stakeholder validation (Silent Review sequence is required, not optional)

• Over-polishing concepts beyond lo-fi standards (violates 30-second comprehension and 15-second sketch thresholds)

• Single-lens evaluation (all three lenses—D/F/V—matter for balanced assessment)

• Rushing to implementation without alignment discovery and conflict articulation

• Creating concepts without environmental and workflow constraint integration from Methods 3/4
