Level 1 Modeling
• Also known as descriptive modeling
• Business oriented
• Purpose is to document simply the process flow
• Usually we omit exception flows
• Can be extended to L2 or L3 (just refine L1)
• Using a basic working set of BPMN elements

PV207 3
• Sequence flow
• Message flow
• Data object (Data store, Message)
• Text annotation
• Link event pair
• Pool and Lane
• Task (User, Service)
• Subprocess (Collapsed, Expanded)
• Start event (None, Message, Timer)
• End event (None, Message, Terminate)
• Gateway (Parallel, Exclusive)

Hungry customer logs into website of Little Vincent’s Pizza, chooses Pizza
Venezia and places his order.
In the pizzeria, ordering system receives order, verifies card transaction
through bank system (external service). If transaction is ok, then bill for 10
dollars is stored in our system and also printed on paper which is resistant to
the fat. If transaction is not ok, then we stop all work related to this pizza.
Meanwhile in the kitchen chef prepares pizza.
When the pizza is ready, delivery boy puts pizza and bill into pizza box. If the
whole preparation of pizza took more than 40 minutes, he adds discount
coupon (otherwise customer wouldn’t be satisfied with our service). Then the
pizza is sent to the customer.

Naming Practices
Spring 2015 PV207
● Activities: Strong verb-Object
○ example: Acquire groceries, Prepare meal, Test software
● Events: Object-Passive verb
○ example: Hunger noticed, Invoice sent, Broken chair received
○ exception especially for timer and blank events
● Split XOR gateways as a question and its outgoing
flows as answers to the question
○ example: Gateway: Is computer ok? Flows: Yes/No
● Pool can have the same name as the process
