Module 3 Business Process Modeling
By the end of this Module you will:

Be able to explain the need for modeling in IS
Explain what is meant by a business process
Explain the purpose of a BPMN model
Use appropriate notation to draw a process model from a case

Business Process Modelling
To design effective information systems.
we first need to understand problems. That means understanding the activities and relationships within that the organizational system.

But organizations are complex open systems, thus it can be difficult to understand what is needed….

Enter models….

“A model is a simple representation of reality that helps us understand how something works or will work”

Modeling in IS

Models help us to visualize a system as it is or as we want it to be.

Models permit us to specify the structure or behaviour of a system in a way that helps us to see how different elements relate and interact with each other.

Models give us a template that guides us in constructing a system.

Models document the decisions we have made. (http://umlguide2.uw.hu/ch01lev1sec1.html).

Modeling in IS
Modelling is critical as a tool in the design of new ways of working.

Process Modelling allows us to represent in detail the current or intended features of critical elements of organisational systems.
we can specify the working of some system at a high level or at a low level of detail.

Process Modelling is a key skill of all business analysts

Any form of Modeling needs three elements:

Constructs:
The components of the Modeling approach
Notation:
The way we choose to represents constructs in the model
Circles for actors, boxes for processes, etc.
Principles:
Formal and informal rules for constructing the model correctly

Business Process Modelling Notation (BPMn) is commonly employed to model business processes.

We have argued above that Modeling is critical to understanding the current workings of some organisation or part of. It is also critical as a tool in the design of new ways of working. The concept of system can be applied hierarchically within the process of Modeling or design. In other words, we can specify the working or some system at a high level or at a low level of detail. In a previous section we discussed building high-level models of purposeful activity. In this section we discuss the application of process Modeling to organisational problems. Process Modeling allows us to represent in detail the current or intended features of critical elements of organisational systems.

The Modeling technique for an IS model uses four main constructs:
Agents

Inventory management process shown as an information model.
A possible process for managing inventory is illustrated as a process model below. It is also known as an information system model because it shows Document flow, Data flow, data storage, and process.

Inventory management process shown as an information model.
Feedback is particularly evident in the decision point stock level < re-order level if ‘true’ this decision point generates an order for new stock that replenishes inventory Activities are reliant on information inputs: shipping note from suppliers; sales order from customers Activities also generate information outputs: purchase order to suppliers or to a data store.

The entire process is made up of a workflow of defined activities Embedded within this flow is inherent control represented by key decision points Diamonds in the diagram are an example of an if statement An if statement is a decision point and a basic way to control flow Module 3 Business Process Modeling 3.1 The need for Modeling and Modeling in IS 3.2 Modeling notation Examples 22 https://www.heflo.com/business-process-modeling-tool/ Module 3 Business Process Modeling 3.1 The need for Modeling and Modeling in IS 3.2 Modeling notation Examples BPMN notation has evolved over time.
