Project durations

Hi Alan

Thanks for your question. You might want to set a milestone with a constraint so that it falls when your various work streams should conclude.

If this is the last task in your project you could turn on the Project Summary (Tools > Options > View and select Show project summary task)

Project will create a summary task at the top of your Project Plan

If the milestone will not be the last task you could try adding the task into a summary containing the work streams. Again the summary task will calculate the number of working days required.

Let me know if either of these approaches answers your question.

Kind regards,

Andrew
