Extended duration when Successor has been started in MS PROJECT 2016

Hi,

my Blog reader has a problem:

“So what if we aren’t moving the project, just adding time to a task where a dependent task was able to start early. As an example
Task A 10 days
Task B 2 days
Task C 5 days

A is a predecessor of B. B is a predecessor of C.
Work is started on B, 50% complete
It is determined that A is going to take longer, 15 days

The Problem: Changing A to 15 days doesn’t cause the times to recalculate for B and C because of the work percentage for B being 50%. Is there an elegant way around this?

The only way I’ve been able to do this is to delete out the percentage, add the days to A, then re-enter the percentages. That isn’t hard on such a small example. But in real life, with larger projects, it just doesn’t work. Suggestions?”

Well, this need an brief explanation, and I will do it in MS PROJECT 2016!

First I’m create Project with schedule as was described by my blog Reader:

As you can see, this is Finish to Start relation. Now, let’s say that Task B is 50% completed, as planned:

and I will get:

Now, let’s suppose that Task A will have 15 days Duration instead of 10:

As you can see, Finish date of the Project is moved to Thursday 26.11.2015. BUT! 50% of previous finished Task 2 is not moved. And that make sense, because MS PROJECT is not supposed to move finished Tasks, or piece od partially Finished Tasks anywhere! If something is done, it is done! No matter of other Tasks! And as you can see the remaining part of Task B is rescheduled to the first working day after Task A is supposed to be finished. For example, if Task A has 12 days duration, the remaining part of Task B will start at Wednesday, 18.11.2015.

The question which really matters here is: “Do we have a right schedule for this Project?” Why is this question so important? As you can see, Task A is Predecessor of Task B, with Finish-to-Start Relationship. And, Task B has been started before Task A has been 100% finished. Something is wrong with that. So if this is case, and Task B should be started before Task A is 100% finished we should consider different relationship (Start-to-Start, for example).

Hope this helps!

Regards.
