Basic PROforma Concepts: Task states
When a process-description is enacted, tasks generally go through a series of states. All tasks are initially dormant; then they are either activated and become in progress, or they are ignored and become discarded. Finally, tasks that are performed become completed.
A task can be in one of four states:
 |
Dormant | The Tallis Engine has not yet determined whether the task needs to be performed. Task colour: Grey |
 |
In progress | The task is currently being performed by the Engine. Task colour: Yellow |
 |
Discarded | The Engine has determined that the task does not need to be performed. Task colour: Black |
 |
Completed | The task has been performed. Task colour: Blue |
The Tallis Engine determines task states according to the relationships between the tasks, and according to the task properties.
