Business Process Modelling
Background
A set of steps a business performs to create value for clients
Consists of 3 components inputs, activities and outputs
What is a business process?
What is a good process model?
Business Processes
Modeling Business Processes
Use the following symbols when drawing business process components in a Cross-functional Flowchart of a business process.

Business Process Modelling
Let’s review a simple process
Activities: A process or sub-process that forms a logical, part of the business process being described by the flowchart. (Use the Process or Sub-process block on flowchart)
Inputs: only database records and documents are seen as inputs. (Use the Document or Data block on flowchart)
Outputs: only database records and documents are seen as outputs. (Use the Document or Data block on flowchart)
Business Analysis 15
What are the components?
External Data, or External Materials used (sometimes called material stores): Data or Material from an external system – not the database/system responsible for data storage/delivery in the business process being described by the flowchart. Use the
Database / External Data block on flowchart) Swimming lanes: a column of the flowchart dedicated
to an actor / user / system in the business process. Decision: a part of the business process where one of
the actors / users / system must decide on one of many process flows that will determine the rest of the process flow. (Use the decision block on flowchart)

More BP components
Always first write out the Input Output Model (IO Model) of the process
Example customer order on line
Business Analysis 17
Before you draw the BP flowchart…
Search for item on line…
System generates search results
Select and view item
Place item in basket
Customer checks out
Checkout
Checkout
Choice
Activity Input Output Responsible1) Customer searches for item Customer2) System generates search results
Item records Search results
System
3) Customer selects and views item
Item record Customer
4) Customer places item in basket
Item record Transaction item record
Customer
5) Customer checks out Customer 5.1) Confirms details Customer record Customer 5.2) Confirms transaction items
Transaction item records
Customer
5.3) Confirms payment details
Proforma Invoice
Customer
6) CHOICE/DECISION – accept transaction?
Invoice Customer
7) IF YES: Accept Invoice Order / Receipt Document
Customer
8) IF NO: Reject Invoice Invoice Customer9) Process Order Order record Customer

Example of IO Model
A swimming lane for each actor involved in the BP – usually three: Customer Administrator / Business actor System
Sometimes only two actors Example: Customer buys item online Actors: Customer and System
