Start date and percentage complete in MS PROJECT 2013 – how are they connected!

I’ve noticed that some Project users do not understand how % Complete and Start date are connected, and because of that they think that MS PROJECT 2013 has a bug.

Let me give you an example. First I will create a simple Project:


Now I will mark Task 2 as 50% completed, and I’ll get:


Now suppose that Task 1 has 5 days duration. If I enter 5 days in duration field I will get:


As you can see, Start date in Task 2 is not changed. And this is not a Bug. Why? Because Task 2  has started with work.What can you do? You can say that Task 2 is 0% completed, and you will get:


Now you can mark Task 2 as 50% completed again.

But I will ask you a question as a Project Manager, and not as a Microsoft Project User. If you establish Finish-To-Start link between Tasks, that means that Predecessor must be finished, before Successor can Start. So, why will you mark Successor as Partial finished? If you can Start Successor before Predecessor ends, you can put a Lead time on Successor, or you can establish another type of Dependencies like Start-To-Start.

    Zdravo, Nenade!
    I was wondering if there is an “Actual Percents Finished-to-Start” link existing in MS Project 2013?
    That is “Task 2 starts as soon, as some percents of work is finished within Task 1”
    Have you seen anything similar?

    Hey there! I know this is kinda off topic but I was
    wondering which blog platform are you using for this site?
    I’m getting fed up of WordPress because I’ve had problems
    with hackers and I’m looking at options for another platform.
    I would be great if you could point me in the direction of a good platform.
