Start this module in Claude Code: Run /start-3-2-1 to begin the interactive experience.

Overview

Module 3.2.1 applies your image generation skills to real PM deliverables. You’ll create the visual assets needed for product pitches: persona portraits, journey maps, wireframes, device mockups, and hero images.

Key takeaway: These techniques work for any pitch or presentation. Once you can generate these five asset types, you can visually communicate almost any product story.

The Scenario

Throughout Module 3.2, you’re a PM at TaskFlow (the course’s fictional B2B SaaS company). You’re pitching TaskFlow Mobile - a new mobile app for operations managers in manufacturing.

Your pitch deck needs:

  1. Persona portrait - “Who are we building for?”
  2. Journey map - “What problem are we solving?”
  3. Wireframe - “What does the solution look like?”
  4. Device mockup - “How does it feel in hand?”
  5. Hero image - “What’s the vision?”

Let’s build each one.

Persona Portraits

Persona portrait examples - cinematic and illustrated styles

What They Are

Persona portraits put a face to your target user. They make abstract user segments feel real and help stakeholders empathize with the people you’re building for.

When to Use

  • Pitch deck “Who” slides
  • User research presentations
  • PRD persona sections
  • Team alignment documents

How to Generate

Basic prompt:

Create a persona portrait of [name], a [role] at [company type].
[Age range], [key characteristics]. Professional but approachable.
For a pitch deck.

Example - Marcus Chen:

Create a persona portrait of Marcus Chen, an operations manager
at a manufacturing plant. Mid-40s, practical, confident but
approachable expression. Wearing work-appropriate attire -
polo shirt, maybe a safety vest. Natural lighting.
For a pitch deck to leadership.

Style Options

StyleBest forExample prompt addition
Photo-realisticExecutive presentations”Photorealistic, professional headshot quality”
IllustratedFriendly/casual contexts”Illustrated in a modern flat style”
StylizedBrand-specific needsReference your style library

Pro Tips

  • Add context clues: Include environment hints (factory floor, office, etc.)
  • Match the tone: Executive pitch = more formal; team wiki = more casual
  • Be consistent: If you have multiple personas, use the same style for all

Journey Maps

Journey map examples - minimalist and hand-drawn styles

What They Are

Journey maps visualize a user’s experience over time - the steps, touchpoints, pain points, and emotions throughout a process.

When to Use

  • Problem definition slides
  • User research findings
  • Solution framing
  • Stakeholder alignment

How to Generate

Basic prompt:

Create a journey map showing [user]'s [process/workflow].
Stages: [list stages]. Show pain points at each stage.
Clean, presentation-ready, 16:9 aspect ratio.

Example - Marcus’s morning:

Create a journey map showing an operations manager's morning workflow.
Stages: Arrive (6am) → Review backlog → Morning standup → Floor walk → Handoff prep.
Show pain points: scattered information, manual tracking, delayed updates.
Clean visual style suitable for a pitch deck. 16:9 aspect ratio.

Style Options

StyleBest for
MinimalistExecutive presentations
Hand-drawnWorkshop/collaborative feel
InfographicMarketing/external use
DetailedDeep-dive presentations

Pro Tips

  • Include emotions: Happy/frustrated faces at each stage add impact
  • Highlight pain points: Red zones or icons draw attention to problems
  • Keep it scannable: 5-7 stages max; detail goes in supporting docs

Wireframe Transformation

Wireframe examples - grayscale and hand-drawn sketch styles

What It Is

Transform rough sketches into polished wireframes. This is perfect for taking meeting whiteboard sketches and making them presentation-ready.

When to Use

  • After brainstorming sessions
  • Early-stage design reviews
  • Quick concept validation
  • When you don’t have a designer available

How to Generate

Basic prompt:

Transform this hand-drawn sketch into a clean, polished wireframe.
Keep the same layout and elements. Professional quality with
clean lines and consistent spacing.

Provide your rough sketch as a reference image.

Example:

Transform this hand-drawn wireframe into a polished mobile app wireframe.
Preserve the layout: header with greeting, task list, shift overview,
bottom navigation. Clean, professional, grayscale with good typography.
Mobile aspect ratio (9:16).

What to Include in Sketches

Even rough sketches should show:

  • Overall layout structure
  • Key UI elements (headers, buttons, lists)
  • Content hierarchy
  • Navigation patterns

Gemini will clean up the visuals while preserving your layout decisions.

Pro Tips

  • Keep sketches clear: Gemini needs to understand your intent
  • Label elements: Write text in your sketch so Gemini knows what goes where
  • Specify fidelity: “Low-fi wireframe” vs “high-fidelity mockup”

Device Mockups

Device mockup examples - iPhone and MacBook frames

What They Are

Device mockups place your wireframes or screenshots into phone/laptop frames. They make digital products feel tangible.

When to Use

  • App store preview images
  • Pitch deck product slides
  • Marketing materials
  • Social media announcements

How to Generate

Basic prompt:

Place this wireframe into a [device] mockup.
Clean background, slight shadow for depth.
Professional, presentation-ready.

Provide your wireframe as a reference image.

Example:

Put this mobile wireframe into an iPhone 15 Pro mockup.
Clean white background with subtle shadow.
Slight 3D angle to show depth. Professional quality.

Device Options

DeviceBest for
iPhoneMobile app pitches
AndroidCross-platform or Android-first
MacBookWeb apps, dashboards
iPadTablet experiences
Multiple devicesResponsive design showcases

Pro Tips

  • Match the context: iPhone for consumer, MacBook for enterprise
  • Use current devices: Latest models feel more premium
  • Consider angles: Flat for clarity, angled for dynamism
  • Add context: Hands holding the device adds authenticity

Lifestyle Shots

Lifestyle shot example - persona in office environment

What They Are

Lifestyle shots show your product in real-world use. They’re the “hero images” that sell the vision - a person using your product in their natural environment.

When to Use

  • Pitch deck covers
  • Landing pages
  • Marketing hero images
  • Social media announcements

How to Generate

Basic prompt:

A [persona] using [product] in [environment].
[Specific details about context]. Natural lighting.
Composition suitable for [use case].

Example:

Marcus, an operations manager in his mid-40s, using TaskFlow Mobile
on the factory floor. He's holding his phone confidently, reviewing
task updates. Manufacturing environment in the background - equipment,
workers, industrial setting. Natural lighting from warehouse windows.
Composition works as a pitch deck hero image.

Composition Tips

ElementGuidance
Subject placementRule of thirds; leave space for text overlay if needed
BackgroundRelevant but not distracting; adds context
LightingNatural usually feels more authentic
ExpressionShould match the story (confident, focused, satisfied)

Pro Tips

  • Use persona consistency: Generate the same “Marcus” across all images
  • Match the environment: Office for B2B SaaS, home for consumer apps
  • Leave text space: If it’s a hero image, leave room for headlines
  • Generate variants: Try different compositions and pick the best

Complete Pitch Deck Example

Here’s how all five assets work together for the TaskFlow Mobile pitch:

Slide 1: The Hero

Asset: Lifestyle shot of Marcus using TaskFlow Mobile on the factory floor Story: “This is the future we’re building”

Slide 2: The User

Asset: Persona portrait of Marcus Chen Story: “Meet Marcus - our target user”

Slide 3: The Problem

Asset: Journey map of Marcus’s chaotic morning Story: “His current workflow is broken”

Slide 4: The Solution

Asset: Polished wireframe of TaskFlow Mobile Story: “Here’s what we’re building”

Slide 5: The Vision

Asset: Device mockup (iPhone with wireframe) Story: “Task management in your pocket”

Total time: 15-20 minutes for all five assets.

Using Your Style Library

Remember the style library from Module 3.1.4? It shines here.

For consistency:

Generate Marcus persona portrait using style #12
Generate journey map using style #15

For exploring options:

Show me all persona styles in my library
Generate Marcus using style #12, #15, and #18 as variants

The more styles you build, the faster this becomes.

Best Practices

Do:

  • Match styles across a deck - consistency looks professional
  • Use TaskFlow context - or your real company context
  • Generate at 1K first - iterate, then go to 2K for finals
  • Save good styles - add them to your library
  • Generate variants - especially for hero images

Don’t:

  • Don’t mix wildly different styles - it looks unprofessional
  • Don’t skip iteration - first drafts are rarely final
  • Don’t over-detail wireframes - they should feel like wireframes
  • Don’t forget context - tell Claude what it’s for

Troubleshooting

Persona doesn’t match description

  • Be more specific about age, expression, attire
  • Provide reference images of the “type” you want
  • Try: “NOT a stock photo feeling, more natural and authentic”

Journey map is too complex

  • Reduce to 5-6 stages maximum
  • Request “simplified, high-level view”
  • Save detailed journeys for separate deep-dive slides

Wireframe looks too polished

  • Explicitly request “low-fidelity wireframe”
  • Ask for “grayscale only, no polish”
  • Specify “sketch-like, not final design”

Device mockup looks fake

  • Request “photorealistic device frame”
  • Add context: “slight shadow and reflection”
  • Try different angles

What’s Next?

You’ve mastered user and product visuals. Next up: strategy and architecture diagrams for stakeholder meetings.

Module 3.2.2 covers system architecture diagrams, prioritization matrices, and product roadmaps - the visuals for CTO, CEO, and board meetings.
