🗺️ Your User Experience Journey
Phase 1: 🎯 Discovery & Onboarding
You’ve just landed on the studio. What’s next?
✅ First Impression: Clean, guided interface with clear entry points
✅ No Installation Required: Web-based, instant access
✅ Guided Setup: Start with a simple project name and description
Pro Tip: Begin with a focused scope. “E-commerce Checkout System” is better than “Everything.”
Phase 2: 📋 Defining Scope & Identifying Actors
Setting the foundation for success
Step 1: Define Your System Scope
Fill out the Scope Description form:
-
System Name: Clear, memorable identifier
-
Purpose: What problem does this solve?
-
Audience: Who will use or benefit from this system?
Step 2: Identify Actors & Use Cases
Add the people and systems that interact with your solution:
| Actor Type | Examples | Role in System |
|---|---|---|
| Primary Actor | Customer, Admin | Initiates key use cases |
| Secondary Actor | Payment Gateway, Email Service | Supports primary flows |
| System Actor | Database, API Layer | Internal components |
✅ AI Assistance: The studio suggests common actors based on your scope
✅ Relationship Mapping: Automatically detects <<include>> and <<extend>> relationships
Phase 3: ✨ AI-Powered Use Case Description Generation
From simple goal to comprehensive specification
How It Works:
-
Select a Use Case: e.g., “Process Customer Order”
-
Click “Generate”: AI analyzes your goal statement
-
Review Output: Get a structured description including:
-
✅ Preconditions & Postconditions
-
✅ Main Success Scenario (Basic Flow)
-
✅ Alternative & Exception Flows
-
✅ Business Rules & Constraints
-
Example Output Structure:
## Use Case: Process Customer Order
**Preconditions**:
- Customer is authenticated
- Shopping cart contains items
**Main Flow**:
1. Customer submits order
2. System validates inventory
3. Payment is processed
4. Order confirmation is sent
**Postconditions**:
- Order status = "Confirmed"
- Inventory updated
- Receipt generated
🔄 Generate, Then Edit: Use AI output as a first draft. Always refine to match your domain specifics.
Phase 4: 🎨 Visual Modeling & Diagram Generation
Transform text into professional UML visuals
One-Click Diagram Generation:
| Diagram Type | Purpose | Best For |
|---|---|---|
| Use Case Diagram | Show actor-system interactions | Stakeholder alignment |
| Activity Diagram | Visualize workflow & decision points | Process optimization |
| Sequence Diagram | Map object interactions over time | Technical design reviews |
| Class Diagram | Model static structure & relationships | Architecture planning |
| ERD | Design database schema | Data modeling sessions |
Workflow:
-
Select your refined use case description
-
Click “Generate Diagram”
-
Choose diagram type
-
Review, customize, and export
✅ Real-time Preview: See changes as you edit descriptions
✅ Export Options: PNG, SVG, PDF, or embed in reports
Phase 5: 🧪 Quality Assurance with AI-Generated Test Cases
Ensure requirements are testable and validated
Automatic Test Case Generation:
From your use case description, the AI produces:
| Test Element | Description | Example |
|---|---|---|
| Test ID | Unique identifier | TC-ORDER-001 |
| Scenario | Test context | “Valid order with sufficient inventory” |
| Steps | Action sequence | 1. Add item to cart → 2. Proceed to checkout |
| Expected Result | Success criteria | “Order confirmed, receipt emailed” |
Interactive Test Management:
-
✏️ Edit: Refine steps or expected results
-
➕ Add: Insert edge cases or negative tests
-
🗂️ Organize: Group by priority, module, or sprint
-
📤 Export: Generate test suites for QA tools
🔍 Best Practice: Generate test cases early to identify ambiguous requirements before development begins.
Phase 6: 📄 Reporting & Collaboration
Share, review, and iterate with stakeholders
Generate Professional Reports:
-
Select “Full SDD” (Software Design Document) or custom template
-
Click “Generate Report”
-
Receive a polished document containing:
-
Executive summary
-
Scope definition
-
Actor/use case catalog
-
Detailed use case specifications
-
Generated diagrams
-
Test case inventory
-
Collaboration Features:
-
🔗 Shareable Links: Grant view/edit access to team members
-
💬 Comment Threads: Discuss specific requirements or diagrams
-
🔄 Version History: Track changes and revert if needed
-
📊 Project Dashboard: Monitor completeness and identify gaps
Phase 7: 🎓 Mastery & Best Practices
Level up your modeling expertise
Tips for Success:
✅ Start Broad, Then Refine: Define full scope before diving into details
✅ Keep Descriptions Focused: One goal per use case = clearer outputs
✅ Use the Dashboard: Regularly check for missing actors or incomplete flows
✅ Iterate with Stakeholders: Share early diagrams to validate understanding
Common Pitfalls to Avoid:
❌ Overloading a single use case with multiple goals
❌ Skipping precondition/postcondition definitions
❌ Ignoring alternative flows (happy path isn’t enough!)
❌ Generating diagrams without reviewing AI output first
