Customer Onboarding To-Be Process

Create a BPMN diagram for a streamlined customer onboarding process. The process should include: - Customer submits application online - Automated validation of required fields - KYC (Know Your Customer) verification by Compliance team - Credit check by Risk Assessment team - Parallel approval from both Sales Manager and Finance Manager - Automated welcome email and account setup - Customer receives login credentials Include swimlanes for Customer, System, Compliance, Risk Assessment, Sales, and Finance.

Expected Outcome

A comprehensive to-be process diagram showing the improved onboarding flow with clear responsibilities, parallel approvals, and system automation.

Requirements Gathering Documentation

Expected Outcome

A clear process map showing the iterative nature of requirements gathering with decision gateways for feasibility checks and approval steps.

Business Process Analysis

Create a BPMN diagram for analyzing and documenting an as-is business process: - Identify process stakeholders - Schedule and conduct process workshop - Document current process steps with stakeholders - Identify pain points and bottlenecks - Measure current process metrics (time, cost, quality) - Analyze process inefficiencies - Propose improvement opportunities - Present findings to management - Get approval for process improvement initiative Include swimlanes for BA, Stakeholders, and Management.

Expected Outcome

A structured analysis workflow showing how BAs systematically document and analyze existing processes before proposing improvements.

Change Impact Assessment

Design a BPMN flowchart for the change impact assessment process: - Receive change request from business - BA analyzes impact on current processes - Identify affected systems and teams - Assess regulatory and compliance implications - Calculate effort and timeline estimates - Conduct risk assessment - If high risk, escalate to steering committee - If approved, create detailed impact report - Distribute to all affected stakeholders Show clear escalation paths and decision points.

Expected Outcome

An impact assessment workflow with decision gateways for risk evaluation and proper escalation procedures.

Advanced Usage Guides

Master these techniques to get the most out of BA Copilot's AI BPMN generator

After generating your initial BPMN diagram, you can refine it through natural conversation. Simply describe the changes you want to make: • "Add a decision gateway after the approval step" • "Move the notification to happen before the final step" • "Add swimlanes for Customer, Sales Rep, and Back Office" • "Split this into two parallel paths" The AI understands BPMN terminology and business process concepts, so you can iterate quickly without manual diagram editing. Each refinement builds on the previous version, allowing you to perfect your process map in minutes instead of hours. Pro tip: Be specific about where changes should occur by referencing existing elements in your diagram.
Swimlanes help organize BPMN diagrams by showing which role or department is responsible for each activity. Here's how to effectively use swimlanes: By Role: Organize activities by job function • Customer, Sales Representative, Manager, Finance Team • Clear handoffs between roles become immediately visible By Department: Show cross-functional processes • Marketing, Sales, Operations, Support • Identifies potential bottlenecks at department boundaries By System: Map system interactions • User Actions, Web Application, Database, Email System • Useful for technical process documentation Best practices: • Keep swimlanes to 3-5 for readability • Minimize crossing arrows between lanes • Group related activities within the same swimlane • Label each swimlane clearly with role/department name

FAQ

Frequently asked questions

Is sign‑in required to generate a BPMN diagram?

No. You can generate one diagram without signing in. Further usage requires a subscription.

Can I export the BPMN diagram?

Yes. You can download as a PNG image, export a polished PDF, or save as a .bpmn file from the diagram editor.

Does this replace a BPMN to PDF tool?

This focuses on AI generation. To convert existing .bpmn files to PDF, use our Free BPMN to PDF Converter.

What's the difference between a BPMN diagram and a BPMN flowchart?
