ALICE represents not only critical and non-critical predecessors/successors but also shows the reason for task criticality: if the task is resource or logic-driven. The Relationship Details help planners easily identify the critical resources such as the labor, equipment, required material quantity, and make data-driven decisions.
Some activities will have several predecessors and/or successors, which might make it hard to follow along by solely relying on the Gantt arrows.
For these situations, you may access the relationship details tab, which will list all predecessors and successors for a given selected task and some metadata related to each logic link.
In addition, you’re able to use the “Select” button to navigate through your logic by following along various logic paths.
Note: Critical Tasks are highlighted in red.
Free or Total Slack (Float) is a crucial number to monitor because it gives you a way to decide which tasks need to be prioritized and which can be pushed back to a later date.
You can see Free and Total Slack values defined by:
Free Slack: the amount of time that a given task can be delayed without affecting any other task in the schedule
Total Slack: the amount of time that a given task can be delayed without affecting the total project duration
You can hover over the information icon to get more granular details such as Free and Total Slacks in hours, Latest Start and End, and if the task is critical or not.
The following video provides an overview of all Criticality Features.
