Process Builder
The system uses Camunda Modeler for designing processes. The modeler can be downloaded from here.
An online version of modeler may also be used however it is recommended that a desktop version be used (above).
Through the Process Builder you can edit or design a new process and you can add, remove and rearrange tasks/phases.
Processes are designed in Camunda Modeler, exported or saved as bpmn20 files and are then uploaded into the Process Setting/Definition to make them effective.
