Milestone with “Finish not later than” constraint and Float Ii n MS PROJECT 2016!

Hi guys,

I have another great question from one of my Blog readers:

“Hi Nenad,

I have another question for you.Suppose you have a task with start date, for example, 7 Nov and 5d duration. Its successor is a finish milestone with constraint ” finish not later than” 18 Nov.

Now I expect to have a float of 5 days, but it isn’t so. Project gives 0d float. Is it a bug?”

No, it is not a bug, and I will show you why in MS PROJECT 2016!

First I will create brand new Project with one Task and one Milestone, and I will make this milestone as Successor of the Task:

Now, I will put the constraint “Finish no later than” for this Milestone, and the date will be 18.11.2016:

and:

Now I will show Detail Gantt View:

I will apply Schedule table:

As you can see, Slack (or Float) is zero. Why? Because with constraint: Finish no later than”, Ms Project knows that Task or Milestone should not finish later than specific date, but it can be finished earlier. So, there is no slack here. but, if I put Must finish on on the Milestone, I will get:

Now, Milestone has fixed date for finish, and it is 18.11.2016, and it should be not finished earlier, so Task has Slack (float) 5 days, e.g it can last 5 days longer!

Hope this clear this issue up!

Regards!
