🗺️ 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:

1. Select a Use Case: e.g., “Process Customer Order”

2. Click “Generate”: AI analyzes your goal statement

3. 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:

1. Select your refined use case description

2. Click “Generate Diagram”

3. Choose diagram type

4. 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:

1. Select “Full SDD” (Software Design Document) or custom template

2. Click “Generate Report”

3. 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
