Transitions & Guards in Flux BPM

About Transitions

In the context of Business Process Management (BPM), a transition represents a change from one stage or state of a process to another. It's a crucial component of a workflow as it dictates the progression of tasks and activities. Transitions are the connectors in a process flow, bridging various stages and ensuring that the process moves forward in a structured and pre-defined manner.

How Does a Transition Occur in Flux BPM?

In Flux BPM, for a successful transition between stages, two essential conditions must be met. Firstly, the current stage's completion criteria need to be fully satisfied. This involves completing all designated tasks and fulfilling the requirements specific to that stage. Secondly, the guard condition must be met. This is an additional check that ensures certain predefined conditions or rules are satisfied before the process can move to the next stage. When both these criteria – the completion of the current stage and the guard condition – are fulfilled, the process is then allowed to transition smoothly to the subsequent stage.

Guard Conditions

Guard conditions are criteria or rules that must be fulfilled for a transition to take place. They act as checkpoints ensuring that all necessary conditions, such as approval from a manager or completion of a prior task, are met before the process moves to the next stage. This mechanism prevents errors and ensures that each stage is appropriately prepared to handle the incoming process.

The Flux Expression Builder enables users to set specific conditions within the guard or execute a logic block. This block performs predefined operations and returns a result, which the transition guard uses to determine if the transition conditions are met, enhancing the system's efficiency and customization.
