MODELLING?
– George E.P. Box (1919-2013)
“Essentially,
all models are wrong;
but some are useful.”
BUSINESS PROCESS MODEL AND NOTATION
(BPMN)
• Released by Object
Management Group (OMG)
• BPMN 2.0: March 2011
• Similar to UML’s Activity
Diagrams
Fairly complex language: over 100 symbols
but
Easy to learn:A handful of symbols cover
many of modelling needs

EXERCISE I
ASSESSING LOAN APPLICATIONS
A loan application is approved if it passes two checks:
I. The applicant’s loan risk assessment, done automatically by a system
II. The appraisal of the property for which the loan has been asked, carried
out by a property appraiser.
The risk assessment requires a credit history check on the applicant, which is
performed by a financial officer.
Once both the loan risk assessment and the property appraisal have been
performed, a loan officer can assess the applicant’s eligibility. If the applicant is
not eligible, the application is rejected, otherwise the acceptance pack is
prepared and sent to the applicant.

EXERCISE II
ORDER DISTRIBUTION
An online store has two warehouses that store different
products in TehranPars and Ekbatan.
When an order is received, it is distributed across these
warehouses: if some of the relevant products are maintained in
TehranPars, a sub-order is sent there; likewise, if some relevant
products are maintained in Ekbatan, a sub-order is sent there.
Afterwards, the order is registered and the process completes.

EXERCISE III
ASSESSING LOAN APPLICATIONS
Once a loan application is received by the loan provider, and
before proceeding with its assessment, the application itself
needs to be checked for completeness.
If the application is incomplete, it is returned to the applicant, so
that they can fill out the missing information and send it back to
the loan provider.
This process is repeated until the application is found complete.

EXERCISE IV
ASSESSING LOAN APPLICATIONS
When a claim related to a major car accident is evaluated, a clerk first
retrieves the corresponding car accident report in the Police Reports
database. If the report is retrieved, it is attached to the claim file.The claim file
and the police report serve as input to a claims handler who calculates an
initial claim estimate.Then, an “action plan” is created based on a “checklist”.
Based on the action plan and the initial claims estimate, a claims manager
negotiates a settlement with the customer.After this negotiation, the claims
manager makes a final decision, updates the claim file to record this decision,
and sends a letter to the claimant to inform him/her of the decision.
Please depict all relevant documents in the model.

EXERCISEV
CLAIMS HANDLING PROCESS AT A CAR INSURER
A customer submits a claim by sending in relevant
documentation.The Customer Service department checks
the documents for completeness and registers the claim.The
Claims Handling department picks up the claim and first
checks the insurance policy.Then, an assessment is performed.
If the assessment is positive, a garage is phoned to authorise
the repairs and the payment is scheduled (in this order). In
any case (whether the outcome is positive or negative), an e-
mail is sent to the customer to notify the outcome.

WE SHOULD LEARNED
• Basic process models in BPMN:
• Simple activities, events, gateways,
data objects, pools, and lanes
• Process model vs. process instance
• Information flow between activities
and events
• Pools and lanes that can be used to
model resources
• Some software tools that supports
BPMN
