Task Calendars and Lag in MS PROJECT 2013

Hi,

today I will answer to this question: “You have 2 tasks which own different task calendars (Standard 5day and 7day calendar). They are connected FS and have a lag, lets say 5 days. Which calendar does the lag use?”

OK! I will show you that in MS PROJECT 2013. First let me create 7-days calendar with MY CALENDAR name:

Now, I am going to modify MY CALENDAR:

OK! Now I will add four Tasks to My Project with 10 days duration each:

Now I will tell that TASK 1, and TASK 4 have MY CALENDAR, as default Calendar, and TASK 2 and TASK 3 have Standard Calendar as default Calendar. I will show that settings only on TASK 1, and you can do the same thing with other Tasks:

Finally I get:

As you can see Task 1, and Task 4 will start on Monday, 25.02.2013, and will finish at Wednesday 06.03.2013, because the work will be performed during a weekend. On the other hand, Task 2, and Task 3 will start on Monday 25.02.2013, but will finish at Friday 08.03.2013, because the work will not be performed at weekend.

Now I am going to connect Task 1, and Task 2, and Task 3, and Task 4as well, and I will get:

Everything looks fine! Notice that Task 2 will start at Thursday 07.03.2013, and Task 4will start at Saturday 09.03.2013.

Now to the point! I will put a 5 days lag for Task 2, and Task 4:

and I will get:

Now, the explanation:

  • Task 1 will finish at Wednesday, 06.03.2013
  • Task 2 will start after 5 days lag, at Thursday 14.03.2013. That is because Task 2 has Standard Calendar, so this 5 days of Lag is only working days (means: Thursday 07.03.2013, Friday 08.03.2013, Monday 11.03.2013, Tuesday 12.03.2013, and Wednesday 13.03.2013)
  • Task 3 will finish at Friday, 08.03.2013
  • Task 4 will start after 5 days lag, at Thursday 14.03.2013. That is because Task 4 has MY CALENDAR, so this 5 days of Lag is working days + weekend (means: Saturday 09.03.2013,  Sunday 10.03.2013, Monday 11.03.2013, Tuesday 12.03.2013, and Wednesday 13.03.2013)

To conclude, MS Project 2013 uses for the lag, the calendar of the successor.

    Great stuff as usual Mr. Nenad.
    I would like to add my contribution for an eventual future post on calendars. When creating a calendar and setting different working hours period specific to some countries for only a limited time; e.g: 1 month for example. We need to pay attention that setting ‘Start date’ and ‘End date’ only will result in MS project 2007 taking into account week-ends in between as working days too.
    Consequently, our Schedule overall is wrong and the FInish date of the project is wrong.
    I found a way to avoid this. Simply, selecting ‘weekly’ as a Recurrence pattern in the exception list.
    Hope this will be helpful. 🙂

    Last bullet in the explanation, the second sentence, I believe it’s a typo when you say “…because Task 2 has MY CALENDAR…”, and you mean “…because Task 4 has MY CALENDAR…”, right?
