Module 07: The Design Phase

Lesson 1: Entering Design Mode

The transition from strategy to creation


You've Built the Foundation

Take a moment to appreciate what you've accomplished:

Module 04: Product Brief — Your North Star

  • Vision and positioning
  • Target users and stakeholders
  • Success criteria and constraints

Module 05: Platform Requirements — Your Boundaries

  • Platforms you're targeting
  • Integrations required
  • Constraints and knowledge gaps

Module 06: Trigger Map — User Psychology Mapped

  • Personas with driving forces
  • Business goals connected to features
  • The "why" behind every decision

This is your strategic foundation. Every design decision you make from here forward references these documents.


The Mindset Shift

Strategy is about discovering and documenting. Design is about visualizing and specifying.

You're moving from:

Strategy Mode Design Mode
What should we build? How should it work?
Why does this matter? What does the user see?
Who is this for? How do they accomplish their goal?
What's possible? What exactly happens?

Both matter. But they require different thinking.


Before We Begin: Why Specifications Matter

Before diving into the design workflow, you need to understand a critical question:

"Why can't we just skip to code?"

Short answer: Because code is 10-20% of the value. Specifications are 80-90%.

Your app exists in specifications. The code is just one possible projection—like compiled output.

This isn't about "doing things the hard way." This is about doing things the professional way with AI-assisted development.

Read Lesson 2: Why Specifications Matter for the complete philosophy behind WDS.

Key insights you'll learn:

  • Code is a lossy projection from specifications
  • Specifications align humans on shared goals
  • Specs are meta-prompts that enable autonomous AI work
  • Professional approach: Prompt → Spec → Code (not Prompt → Code → Debug hell)
  • Why this represents "the spirit of BMad v6 through the lens of a designer"

This foundation is critical. Read Lesson 2 before continuing.


Meet Freya

Freya is your design partner for this phase.

What Freya does:

  • Thinks WITH you, not FOR you
  • Asks "WHY?" before "WHAT?"
  • Connects every decision to your Trigger Map
  • Won't let you skip the hard thinking

What Freya doesn't do:

  • Create pretty pictures without substance
  • Make decisions for you
  • Let you design in isolation from strategy
  • Accept "I don't know" as a final answer

She's not a pixel pusher. She's a thinking partner who happens to work with visuals.


The Freya Approach

Freya's first question is always strategic:

"Looking at your Trigger Map, which persona's journey should we design first?"

Not: "What color should the button be?"

Every design decision connects back to your strategic foundation. If it doesn't connect, it gets questioned.


The Design Workflow

Nine modules. Eight steps. One coherent journey.

Outline → Sketch → Storyboard → Specify → Components → Visual → System → Deliver
Step What You Do What You Create
Outline Scenarios Define user journeys Scenario outlines
Conceptual Sketching Visualize default states Rough sketches
Storyboarding Show transformations Keyframe sequences
Specifications Document every detail Complete specs
Components Define reusable patterns Component definitions
Visual Design Apply visual language Polished designs
Design System Organize for reuse System documentation
Delivery Package for implementation Delivery package

Not Strictly Linear

You'll loop back. That's expected.

  • Sketching reveals gaps in your scenario outline
  • Storyboarding exposes missing states
  • Specifications surface component needs
  • Visual design raises consistency questions

The loop is the process. Don't fight it.


Multiple Entry Points

Every step offers choices for how you start:

Entry Point How It Works
I have a sketch You provide, AI refines
I have inspiration You share, AI extracts patterns
Dream it up AI creates options, you pick
Let's discuss Conversation shapes the concept

Same step. Same output. Different starting points.

You're not forced into one way of working. Use what feels natural for each situation.


Creative Discipline

"Creative discipline enables creativity, not constrains it."

This phrase captures the WDS approach to design.

Without discipline:

  • Endless exploration with no conclusion
  • Beautiful mockups that solve wrong problems
  • Scattered work that can't be implemented
  • Decisions without rationale

With discipline:

  • Focused exploration with clear outcomes
  • Beautiful mockups grounded in strategy
  • Coherent work ready for implementation
  • Every decision documented with WHY

Structure doesn't limit creativity. It channels it.


What You'll Create

By the end of this phase:

Artifact Purpose
Scenario outlines The journeys you're designing
Conceptual sketches Visual explorations of each view
Storyboards How elements transform
Detailed specifications Every decision documented
Component definitions Reusable patterns identified
Visual designs Final look and feel
Design system Your component library
Delivery package Ready for Idunn to implement

Design System

Remember the choice from setup:

Mode What Happens
1. None Ad-hoc styling, no extraction
2. Building System grows from your work
3. Library Use external + your branding
4. Existing Import from previous projects

This affects how Freya works with you throughout the phase.

Mode 1-2: You're creating the design language as you go Mode 3-4: You're working within established patterns

Neither is better. Just different workflows.


The Core Principle

Every pixel has a reason. Every interaction traces back to user psychology. Every component connects to a business goal.

Nothing is decoration. Everything is decision.

When you can explain WHY something exists, you've designed well.

When you can't explain it, something's missing.


Ready to Design

You have:

  • Strategic foundation (Product Brief, Trigger Map, Platform Requirements)
  • A thinking partner (Freya)
  • A clear workflow (8 steps)
  • Flexible entry points (multiple ways to start each step)

Let's begin.
