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.
