Business Analysis Lecture 5:Business Process Modelling
Business Process Modelling Business Analysis 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
What is a business process? A set of steps a business performs to create value for clients Consists of 3 components inputs, activities and outputs
Business Process Modelling Business Analysis Use the following symbols when drawing business process components in a Cross-functional Flowchart of a business process.
What are the components? Business Analysis 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)
More BP components Business Analysis 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)
Before you draw the BP flowchart… Business Analysis Always first write out the Input Output Model (IO Model) of the process Example customer order on line
Example of IO Model Business Analysis
Drawing the BP flowchart Business Analysis • 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
