Monitoring task slippage

For tasks, slip is the difference between the report date of a specified progress period and the start or resume date of a task. A positive value indicates that work is ahead of schedule; a negative value indicates that work is behind schedule. For summary and expanded tasks, slip is calculated as being the difference between the report date and the task's effective progress date. The effective progress date for a summary or expanded task is calculated from the task's percentage complete and duration. The percentage complete for a summary or expanded task is calculated as the total actual duration of the child tasks, divided by the total duration of the child tasks. You can display the Slip field in the spreadsheet and you can filter for tasks with a particular amount of slip, which helps you to identify tasks which are very far behind schedule - or very far ahead of schedule.

If a summary or expanded task contains a gap between the last completed work and the work that remains to be completed and if the report date is located at some point within this gap, the Slip field for summary and expanded tasks shows zero.
