- 20-30 minutes
Example Process: Customer Onboarding
We'll create a complete flowchart for a B2B SaaS customer onboarding process, from initial sign-up through first successful use.
Process Overview
Goal: Transform new sign-ups into active, successful users
Stakeholders:
- New customer
- Sales team
- Customer success team
- Technical support
- Product (automated systems)
Success Criteria:
- Customer completes profile setup
- Account is properly configured
- Customer completes first key action
- Customer is set up for ongoing success
Step 1: Define Process Boundaries
Before creating your flowchart, clearly define where the process starts and ends.
Questions to Answer
- 
Start Point: When does this process begin? - Answer: User clicks "Sign Up" on website
 
- 
End Point: When is the process complete? - Answer: User completes first successful workflow in product
 
- 
What's In Scope: What activities are included? - Answer: Sign-up, email verification, profile setup, account configuration, onboarding tour, first use
 
- 
What's Out of Scope: What's excluded? - Answer: Marketing activities before sign-up, ongoing product usage after onboarding
 
Document Boundaries
Create a workspace in DiagramKit.AI and add this context to your flowchart description:
Title: Customer Onboarding Process
Description: B2B SaaS customer journey from sign-up through first successful use
Scope: Registration through first workflow completion
Out of Scope: Pre-signup marketing, ongoing usage
Owner: Customer Success Team
Last Updated: 2025-01-13
Pro Tip: Clear boundaries prevent scope creep. If you identify related processes, create separate flowcharts and link them with off-page connectors.
Step 2: Identify Stakeholders and Roles
List all people and systems involved in the process.
Stakeholder Analysis
| Stakeholder | Role | Responsibilities | System Access | |-------------|------|------------------|---------------| | New Customer | Primary Actor | Completes signup, provides info | Web app | | Sales Team | Qualifier | Reviews account, assigns tier | CRM, Admin panel | | Customer Success | Guide | Sends welcome, schedules calls | CRM, Email platform | | Technical Support | Resolver | Handles technical issues | Support portal, Admin | | System (Automated) | Executor | Sends emails, provisions account | Backend services |
Responsibility Matrix (RACI)
For each major process step, identify who is:
- Responsible - Does the work
- Accountable - Approves/owns outcome
- Consulted - Provides input
- Informed - Kept updated
Example: Email Verification Step
- Responsible: System (sends email)
- Accountable: Customer Success Manager
- Consulted: Marketing (email copy)
- Informed: Sales (signup notifications)
Swimlanes Coming Soon: A future DiagramKit.AI update will support swimlanes, making it easier to show responsibilities visually. For now, use descriptive labels like "Sales: Qualify Account" to indicate responsibility.
Step 3: Map the Happy Path
Start with the ideal scenario where everything goes right.
Create the Main Process Flow
- 
Create a new flowchart named "Customer Onboarding - Happy Path" 
- 
Add the start point: - Use Start/End shape
- Label: "User Clicks Sign Up"
 
- 
Add main process steps in sequence: - Process: "Display Registration Form"
- Data I/O: "User Enters Details (Name, Email, Company)"
- Process: "Validate Input"
- Process: "Create User Account"
- Process: "Send Verification Email"
- Data I/O: "User Clicks Verification Link"
- Process: "Activate Account"
- Process: "Display Welcome Dashboard"
- Process: "Show Onboarding Tour"
- Data I/O: "User Completes Tour"
- Process: "Prompt First Workflow"
- Data I/O: "User Creates First Workflow"
- Process: "Record Onboarding Complete"
- Start/End: "Onboarding Success"
 
- 
Connect all steps with arrows flowing top-to-bottom 
AI Shortcut
Instead of manually adding each shape, use the AI prompt bar:
Create a customer onboarding flow: Start with user signup,
validate email, send verification, activate account, show
welcome dashboard, onboarding tour, prompt first workflow,
complete onboarding
The AI will generate the basic structure, which you can then refine.
Step 4: Add Decision Points
Real processes have branches where different paths are possible.
Identify Decisions
Where do yes/no questions occur in your process?
Common Decision Points:
- Is input valid?
- Is email verified?
- Is account qualified (enterprise vs. free)?
- Did user complete onboarding tour?
- Was first workflow successful?
Add Decision Shapes
- 
After "Validate Input" add a Decision: - Label: "Input Valid?"
- Yes path → Continue to "Create User Account"
- No path → "Show Error Messages" → back to "User Enters Details"
 
- 
After "Send Verification Email" add a Decision: - Label: "Email Verified Within 24 Hours?"
- Yes path → "Activate Account"
- No path → "Send Reminder Email" → Check if 3 days passed
 
- 
After "Activate Account" add a Decision: - Label: "Enterprise Account?"
- Yes path → "Notify Sales Team" → "Sales: Qualify Account" → Continue
- No path → Continue directly
 
- 
After "Show Onboarding Tour" add a Decision: - Label: "Tour Completed?"
- Yes path → Continue
- No path → "Offer Skip Option" → Decision "Skip?" → Continue or back to tour
 
- 
After "User Creates First Workflow" add a Decision: - Label: "Workflow Successful?"
- Yes path → "Record Onboarding Complete"
- No path → "Offer Help" → "Support: Assist User" → Back to workflow creation
 
Label All Branches
Every decision branch must be labeled:
- Use "Yes/No" or "True/False"
- Or specific values: "Enterprise", "Free", "Trial"
- Place labels on connection lines near the decision
Common Mistake: Unlabeled decision branches cause confusion. Always make outcomes explicit.
Step 5: Add Exception Handling
Real processes encounter errors and exceptions.
Common Exception Scenarios
- 
Technical Failures - Database unavailable
- Email service down
- API errors
 
- 
User Issues - Invalid payment method
- Duplicate account
- Incomplete information
 
- 
Business Rules - Account doesn't meet qualification criteria
- Region restrictions
- Capacity limits
 
Add Error Paths
After "Create User Account" add:
- Decision: "Account Created Successfully?"
- No path → "Log Error" → "Display Friendly Error" → "Notify Technical Support" → "Offer Retry" → Back to form or End
After "Send Verification Email" add:
- Decision: "Email Sent Successfully?"
- No path → "Log Email Failure" → "Notify Support" → "Retry Email" → Decision "Retry Successful?" → Continue or End with error
Error Handling Best Practices
- Always log errors for debugging
- Show user-friendly messages (not technical errors)
- Provide recovery options (retry, contact support)
- Notify appropriate teams
- Track error rates for process improvement
Step 6: Add Automated vs. Manual Steps
Distinguish between automated system actions and manual human tasks.
Visual Differentiation
Use consistent labeling conventions:
Automated (System):
- "System: Create Account"
- "System: Send Email"
- "System: Log Activity"
Manual (Human):
- "Sales: Review Account"
- "User: Enter Information"
- "Support: Assist with Setup"
Alternative: Use color coding (if your team prefers):
- Blue shapes: Automated
- Green shapes: User actions
- Orange shapes: Internal team actions
Documentation Tip: Include an automation percentage in your flowchart description. Example: "85% automated, 15% manual intervention required"
Step 7: Add System Integrations
Show where the process interacts with external systems.
Systems in Customer Onboarding
- 
Database - User account storage - Use Database shape
- Label: "Save User Record"
 
- 
Email Service - Verification and welcome emails - Use Cloud shape (if available) or Process
- Label: "Email Service: Send Verification"
 
- 
CRM System - Sales tracking - Use Database or Document shape
- Label: "CRM: Create Lead Record"
 
- 
Analytics - Track onboarding metrics - Use Database shape
- Label: "Analytics: Record Signup Event"
 
Add Integration Points
Insert Database and Cloud shapes at appropriate points:
- After "Create User Account" → Database: "Save User Record"
- After "Send Verification Email" → Cloud: "Email Service API"
- After "Notify Sales Team" → Database: "CRM: Create Lead"
- After "Record Onboarding Complete" → Database: "Analytics: Track Conversion"
Step 8: Add Time Elements and SLAs
Business processes often have timing requirements.
Time Annotations
Add time information in labels or descriptions:
- "Send Verification Email (Immediate)"
- "Sales: Review Account (Within 2 hours)"
- "Follow-up Email (After 3 days if no verification)"
- "Support Response (Within 4 hours)"
SLA Tracking
If your process has Service Level Agreements:
- Add Decision points for time checks
- Route violations to escalation processes
- Document SLA requirements in flowchart description
Example:
After "Notify Sales Team" → Decision: "Responded Within 2 Hours?"
  → No → "Escalate to Sales Manager" → "Manager: Assign Account"
  → Yes → Continue normal flow
Metrics Matter: Document key metrics in your flowchart description:
- Average completion time: 15 minutes
- Verification rate: 87%
- Completion rate: 68%
- Drop-off points: Email verification (13%), First workflow (19%)
Step 9: Identify Optimization Opportunities
Use your flowchart to find improvement areas.
Analysis Questions
- 
Bottlenecks: Where do delays occur? - Email verification takes 24+ hours for some users
- Sales qualification adds 2+ hour delay for enterprise
 
- 
High-Touch Points: Where is manual work required? - Sales review could be automated for small accounts
- Support frequently helps with same issues
 
- 
Drop-off Points: Where do users abandon? - 13% don't verify email
- 19% don't complete first workflow
 
- 
Redundancies: Are there unnecessary steps? - Multiple email confirmations could be consolidated
- Redundant data entry between forms
 
- 
Error-Prone Areas: Where do failures happen? - Payment validation frequently fails
- API timeouts during high-traffic periods
 
Mark Improvements on Flowchart
Use annotations or a separate optimization flowchart:
- Add text annotations: "OPTIMIZATION: Automate small account qualification"
- Create a second version showing proposed improvements
- Use different colors to highlight changes
- Document expected impact in description
Example Improvements:
- Reduce email verification time by adding SMS option
- Automate qualification for accounts under 50 users
- Create knowledge base to reduce support intervention
- Add in-app guides to reduce drop-off at first workflow
Step 10: Add Compliance and Audit Requirements
Many business processes have regulatory or audit requirements.
Compliance Considerations
Data Privacy (GDPR, CCPA):
- Add: "User: Accept Privacy Policy" before account creation
- Add: "System: Log Consent" after acceptance
- Add: Decision: "Marketing Consent?" with separate tracking
Security:
- Add: "Validate Email Domain" after input
- Add: "Check Against Blocklist" before account creation
- Add: "Enable MFA Option" after activation
Audit Trail:
- Add: "Log Account Creation Event" after each major step
- Add: "Record Time Stamps" for compliance
- Document retention periods in description
Audit Checkpoints
Add audit logging at key points:
- Account creation
- Email verification
- Account qualification
- First successful use
- Any manual interventions
Use Database shapes labeled "Audit Log: [Event Name]"
Compliance Requirement: Some industries require detailed audit trails. Ensure your flowchart documents all required logging points.
Step 11: Create Supporting Documentation
A flowchart alone isn't enough for full documentation.

Pro Tips for Business Process Mapping
Start with Interviews: Talk to everyone involved in the process before creating your flowchart. They'll know details and exceptions you might miss.
Shadow the Process: Walk through the actual process in real-time. You'll discover informal steps and workarounds not in official documentation.
Use Actual Data: Base time estimates and success rates on real metrics, not assumptions. Analytics reveal the truth.
Plan for Exceptions: Spend 30% of your time on the happy path and 70% on exceptions, errors, and edge cases. That's where the complexity lies.
Version Control: Keep old versions when updating processes. They're valuable for understanding how processes evolved and for compliance audits.
