However, the framework is set up in such a way that it can easily be combined with other workflow systems. The ideas behind the tool can be beneficial for BPM practitioners willing to improve the way of executing processes in their own organisations as well as for researchers/technicians working on business process visualisation and human-computer interaction.

In order to use the YAWL Visualisation Framework, one needs firstly to install some web applications in the webapps directory of Tomcat. Moreover, it is needed to enable this framework in YAWL, which is disabled by default.
The following steps need to be done on the machine that hosts the tomcat installation used for the YAWL Server.
Please click on the link below to download the installer that will perform some operations automatically. The only required information is to specify the webapps directory of the tomcat installation.
The next step is to enable the framework in the YAWL Resource Service. In order to do so, the parameter EnableVisualizer needs to be changed to true in the file webapps\resourceService\WEB-INF\web.xml as highlighted in red:
Once the framework is enabled in the YAWL, database visualization needs to be created in the local installation of PostgresSQL. The Visualisation Designer takes care of this operation. When the designer is launched the first time and the database is not found on the local machine, this will attempt to create the database on the local host.
At this point in time, the installation is completed. From this moment on, users can use the Visualisation Designer to create maps, define positions for tasks. Moreover, they can find in the standard work-list handler the button to launch the Visualisation Applet and, hence, take advantage of this new visualiser.
