Modelling

What is a business process? What are the rules for a business

process? Visually represent a BP by

drawing a Cross-functional Flowchart (swimming lanes) model of the process

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 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

Invoice   Customer

7) IF YES: Accept Invoice Order / Receipt Document

8) IF NO: Reject Invoice Invoice   Customer

9) 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
