The document provides guidance on business process modelling and mapping. It defines business process modelling and the three main types of process models. Process mapping is described as a technique to diagrammatically model processes by representing the steps, participants, and decision logic through a visual map. The document then provides instructions on how to produce a process map, including identifying boundaries and participants, drawing the initial flow, and adding and reviewing details like swimlanes and decision points. An example process map is also included to demonstrate a completed map.

3. What is business process modelling?
Business process modelling is a means of
representing the steps, participants and decision logic
in business processes.
There are three main types of process models:

1. Descriptive models: written explanations of the
processes
2. Active models: a working model that represents
the processes (eg. computer simulations)
3. Diagrammatical models: a diagram that shows
the processes and the relationships between
them (eg. process maps and flowcharts.)
This guide will focus on process maps.

4. What is process mapping?
Process mapping is a technique of
diagrammatical modelling.
The diagram represents a series of
processes and how they are related.
Process mapping provides a representation
of who does what and in what order.

Process mapping helps to clarify the steps
involved in a particular process.
It is used for:
• understanding the current processes
• clarifying responsibilities
• identifying process inefficiencies
• designing new procedures
• training

6. How to produce a process map
• Consult with the experts. These are the people managing and working with
the process.
• Identify the boundaries. Where does the process begin? where does it end?
• Identify the participants. What roles are involved in the processes?
• Hand draw the process in front of the expert, getting then to confirm the
steps.
• Identify the steps. What is done first? What is done next? By who?
• Identify the decision points. What are the alternatives? What determines
which alternative is chosen?
• Draw an initial process flow. Draw and label the swim lanes (see next slide

for details) using standard symbols.
• Check for completeness. Are all participants represented?
Are all processes shown? Are there any alternatives that
have not been considered? Refine and finalise.
• Review with the experts to ensure completeness.

7. Draw and label the swim lanes

The swim lanes represent the area of involvement of each
participant who has a role in the processes being mapped.
The participant may be an individual, a team, a department
or an organisation.

Starting at top left with the start symbol.
Draw processes along the swim lane, and use arrows to
represent the sequence.
Each process is given a number, and starts with a verb.

When a process is performed by a different participant
switch lanes. If the next step depends on a decision show
this as in the example above, labelling the alternatives and
showing the steps that follow.

Complete the process map
Remove any unused swim lanes.
Make sure there is one start point and all flows
have an end point.
Check that all decision points have all options
labelled and have flow arrows to the next step.
Review with participants for verification.
An example of a completed process map is shown
on the next slide.
