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.
