Hi,

very often I receive question like: “My Task remains 99% completed, and I do not know why?”, or “All Tasks are 100% completed but the whole project is 99% completed. Why?”

Hera are two most often reasons for that. Of, course I will show you that with MS PROJECT 2013!

First I am going to create new Project (in Gantt Chart I added %Complete Column):

and two Resources (one Work, and one Material):

I will assign John to Task1 and Task2, and 100 Bricks to Task 2 (you know how to do that, don’t you?), and I will get:

Now I will switch to the Task Usage View, and I will get:

Now I will mark John as 100% completed on both Tasks:

and:

I will switch to the Gantt Chart, and I will get:

As you can see, Task 2 is 99% completed, even John has finished his work. Why? Because, I didn’t mark Material Resource as completed, yet. So, now I will do it:

This means that I actually spent 100 Bricks on the Task2. Let’s see Gantt Chart again:

You can see that all Task are 100% Completed, but still the whole Project is on 99% completed. Why? Because I didn’t mark Milestone as completed (no matter that Milestone has 0 days duration). If I mark that as 100% completed I will get:

To conclude, If you want to have your Task 100% completed you should finish all your work and spend all Material so that Work, and Actual Work are the same, and Remaining work should be 0%.

And for whole Project to be completed you should have all Tasks, and Milestones 100% completed.

Respect that and everything would be perfect!

Regards!
