SIPOC Diagram Examples

These SIPOC diagram examples show how different teams use the five-column format to scope and communicate processes. Each example names the SIPOC elements and explains what makes the diagram useful for that context.

Real examples

Customer support ticket handling

Who uses it: Support team lead documenting the ticket resolution workflow

Suppliers: Customer, Knowledge Base, Engineering
Inputs: Ticket description, SLA info, Known issues
Process: Triage → Diagnose → Resolve → Validate → Close
Outputs: Resolution notes, CSAT feedback, KB articles
Customers: End user, Support manager, Product team

Why this works: This SIPOC makes it clear that the Knowledge Base is both a supplier (of known fixes) and a customer (of new articles after resolution). Seeing this dual role helps the team prioritize KB maintenance.

Order fulfillment process

Who uses it: Operations manager mapping the order-to-delivery pipeline

Suppliers: Customer, Inventory system, Payment gateway, Shipping carrier
Inputs: Order details, Stock levels, Payment confirmation, Shipping label
Process: Receive order → Verify payment → Pick items → Pack → Ship
Outputs: Packed order, Tracking number, Invoice, Inventory update
Customers: End customer, Finance team, Warehouse manager

Why this works: The five-column format shows that the shipping carrier is both a supplier (of tracking labels) and a customer (of the packed parcel). This clarifies the handoff point where responsibility transfers.

Employee onboarding

Who uses it: HR manager designing a standardized new-hire process

Suppliers: Hiring manager, IT department, Facilities, Payroll
Inputs: Offer letter, Equipment request, Desk assignment, Tax forms
Process: Send welcome email → Set up accounts → Prepare workspace → Orientation → First-week check-in
Outputs: Active accounts, Assigned desk, Signed policies, Onboarding survey
Customers: New hire, Hiring manager, Team members

Why this works: Onboarding involves multiple suppliers (IT, Facilities, Payroll) feeding into one process. The SIPOC format highlights dependencies — if IT delays equipment setup, the entire onboarding timeline slips.

IT incident management

Who uses it: IT service manager following ITIL practices

Suppliers: End user, Monitoring system, Vendor support
Inputs: Incident ticket, Alert notification, Vendor SLA
Process: Log incident → Categorize → Investigate → Resolve → Close
Outputs: Resolution record, User notification, Root cause report
Customers: End user, Service desk manager, Problem management team

Why this works: The root cause report output feeds into the Problem Management process as an input — showing how one SIPOC can connect to another in a larger process architecture.

Restaurant order-to-table

Who uses it: Restaurant manager optimizing kitchen workflow

Suppliers: Customer, POS system, Food vendors
Inputs: Order ticket, Inventory levels, Ingredient prep
Process: Take order → Fire dish → Plate → Expeditor check → Serve
Outputs: Plated dish, Completed order ticket, Customer feedback
Customers: Diner, Kitchen manager, Inventory manager

Why this works: The expeditor step in the Process column is a quality gate — it verifies the output matches the input (order ticket) before delivery to the customer. The SIPOC makes this checkpoint visible.

Purchase requisition

Who uses it: Finance or procurement analyst mapping the approval chain

Suppliers: Requester, Budget owner, Vendor catalog
Inputs: Purchase request, Budget approval, Vendor quote
Process: Submit request → Budget check → Manager approval → Issue PO → Receive goods
Outputs: Purchase order, Payment authorization, Receipt record
Customers: Requester, Vendor, Accounts payable

Why this works: The budget check step is a decision gate — if the budget is unavailable, the process routes to an exception path. The SIPOC captures the normal flow and makes it easy to identify where exceptions occur.

Tips for better study mind maps

  • Start with the Process column first — it is easier to identify inputs and outputs once the steps are listed.
  • Keep process steps at a high level (4–7 steps). If you need more detail, create a separate flowchart for that process.
  • A supplier or customer can be a person, a team, a system, or another process — be specific about which.
  • Use the SIPOC as a scoping tool before creating detailed process maps — it prevents scope creep.
  • Review the diagram with people from each column to catch missing inputs or unserved customers.
