Summary Tasks on the Critical Path?

Hi All,

 

Beginner Project user here. Having an issue with some summary tasks appearing on my critical path, it seems in lieu of the sub-tasks that are actually critical. Has anyone seen this before?

 

We have tried leveling resources, double checked that the summary tasks are not listed as predecessors anywhere, adjusting start/end dates, and adjusting constraint types.

 

Greatly appreciate any suggestions.

 

 

 

 

  • Barry --

    In Microsoft Project, any task that is not 100% complete AND has a Total Slack value of 0 days is considered a Critical task. This means that summary tasks can be Critical tasks. To see this with your own eyes, apply the Gantt Chart view. Right-click on the Duration column header and select Insert Column on the shortcut menu. In the list of available task fields, select the Total Slack field. Right-click on the Duration column again and select Insert Column on the shortcut menu. In the list of available task fields, select the Critical field. Examine the summary tasks in question. If you see a Total Slack value of 0d and a Yes value in the Critical column, this indicates that the summary task is a Critical task. Hope this helps.

      Dale_HowardMVP Thank you Dale - that makes sense. So, in theory, manually adjusting the duration of summary tasks to add an extra day of slack time even if it is not needed in any of the sub-tasks should clear this issue? 

      • blasky -- Changing the Duration of summary tasks is a BAD idea, as Microsoft Project will automatically change the Task Mode setting to Manually Scheduled for the summary tasks. What you are describing is not an issue or a problem. It is how Microsoft Project displays the Critical Path, and I think you need to adjust your expectations accordingly. Hope this helps.
