Business Process Modeling¶
This section is a collection of detailed guides teaching the reader the various intricacies of BPMN and our extensions to BPMN.
Business Process Model and Notation (BPMN)¶
Provides a standard notation that is understandable by many different business employees/stakeholders and makes for the maintenance of these workflows easier.
Business Process Model and Notation (BPMN) is the global standard for process modeling and one of the most important components of successful Business-IT-Alignment.
More and more organizations are using BPMN and in more and more universities BPMN is taught as a subject. These are the reasons:
- Standard - BPMN is managed by OMG , an established institution responsible for multiple worldwide standards including UML. The standard is supported by many software products making it less dependent on any particular vendor’s products.
- Simplicity - The principle behind BPMN is rather simple enabling a quick uptake.
- Power of expression - If necessary, you can describe precisely how a process should function with BPMN. However, this is more difficult than only roughly describing the process. This way of precise modeling is possible, but not mandatory.
- Implementation in IT - BPMN has been primarily developed to support the technical implementation of processes (“Process Automation”). The more important the IT is in a company, the more helpful the use of BPMN becomes.
Adding the BPMN specification to IFS Cloud allows someone already familiar with BPMN to be able to configure the different actions using our Workflow Designer. The different BPMN symbols and elements, such as tasks, events and gateways are all part of the BPMN specification, this means the workflow functionality will be able to be understood, maintained and amended by our customers many business analysts, developers or subject matter experts.
IFS BPMN Extensions¶
IFS provides pre-created tasks that implement IFS specific delegates. These can be initialized in the Workflow by creating a new task and then selecting the type of task.
Below is a snapshot of the IFS Process Enrichment, IFS Projection and IFS REST Call type options in the list.
Expression Language can be used within a Workflow to define and evaluate small script-like expressions. Expressions are evaluated using Java Unified Expression Language (JUEL).
For detailed information, refer to the Camunda documentation link.
Below is the generated XML for the script task.
Refer Camunda Documentation link for more information.
As shown in the figure below, arithmetic can be used on different numeric variables, and the results set in the execution variables to be used in another process state.
The Date object contains information about the:
Dates can be manipulated using built-in functionality in the Date object. In the figure below, days, months, and years can be added or subtracted to the current date. Time can also be added or subtracted by seconds, minutes, and hours using the built-in functionality.
To concatenate a string, the ‘+’ can be used to concatenate multiple strings and variables together. As shown in the figure below, the string concatenates two variables retrieved from the execution.
