A Task or Milestone with a value greater than the user defined or default value (44 days) of total slack.
Why does it matter if items in the project have Very High Total Slack?
Very high total slack is an indicator of missing predecessors or successors
Resolving Negative Slack
Perform the Audit and Click on each item in the resulting tasks list to go to the offending task. You can also click Filter for Items Below to display tasks with audit issues and record the offending condition in the Integrity Note log field.
Schedulers should work directly with subject matter experts and the project team to examine work flow and life-cycle models that are applicable to the project. If it is determined that predecessors and successors are missing they should be added to the appropriate tasks.
