today I will show you how to use Option: Calculate multiple critical paths in MS PROJECT 2013!
What is Critical Path indeed? This is the longest path which show you how long will a Project Duration be. It is also a path in which if any task is late, the whole Project will be late. So, it has no Slack!
OK! Let me create brand new Project:
or, graphical View:
Now I’ll switch to Detail Gantt View:
As you can see Critical path is on upper branch of Tasks. Task 4, and Task 5 have Slack = 9 days. It means that they can slip for 9 days without affecting Project end date.
Because Task 4, and Task 5 are in independent branch you can consider this branch Critical as well. So, if you want to see those Tasks as critical you should follow this steps:
and you will get:
Now you see both branches (independent) as Critical.
Let me give you an advice. It doesn’t make a sense to have multiple independent branches in a Project. You should always have one common Task at the end of the Project, or at least, one milestone. I always have a milestone at the end of the Project.
I will create one and I will put Task 3, and Task 6 as Predecessors to that milestone:
Let’s look at Detail Gantt again:
Now, I have only one Critical Path, and Option: Calculate multiple critical paths is still on.
And this is best practice how to make right Schedule for your Project. To conclude, avoid independent branches in you Project!
