Introducing my second guest blogger: Nenad Trajkovski from the blog: http://ntrajkovski.com/. Nenad has been one of my favorite bloggers since I started working with MS Project years ago. I have retweeted a number of his very interesting blog posts on numerous occasions. He has a great style of blogging where he uses easy to understand images more than he uses words. So when we bumped into each other at the Project Conference 2014 I just had to ask if he was willing to do a guest post on my blog. Because my post on date related planning has seen some high attention lately I wanted to ask Nenad to share his view on the matter. Without further ado, here is his post.
Hard constraint vs. Deadline
Suppose that you want to know when you have exceeded your project finish data. Here is the sample Project:
Now suppose that you want your house to be finished at Wednesday, 09.04.2014. You can set: Must finish on constraint on the Milestone: House is finished:
And you will get:
This is a warning that tells me about a potential Schedule conflict, but I decided to go on with this Constraint. Now, suppose that “The roof” needs 4 days to finish instead of three days:
I get another warning this time it tells me there will be a schedule conflict, but I decided to go on. So I get:
A better approach
As you can see, this scenario doesn’t make sense, because “The roof” will be finished at Thursday 10.04.2014, and the house will be finished one day before (Wednesday, 09.04.2014), which is nonsense. Hard constraints should be avoided. I will now return to my previous scenario without Constraint:
And I will make Wednesday, 09.04.2013, as Deadline:
And I’ll get:
Now, again suppose that roof need 4 days to finish instead of three days:
My project will be (and it WILL BE), late, and I’ll get a warning message in Info column about that. This is much better approach!
Hi Readers it’s me again, Erik. I hope you enjoyed the post about Deadlines being a better option than setting hard constraints like “must finish on” and “start no earlier than”. For my clients the approach of using deadlines has always resulted in a better understanding of the product.
And just like Bonnie, I would welcome back Nenad any time to do another guest post! Here is his own blog again, for good reference, drop him a line and say you read our blog, he will love that: http://ntrajkovski.com/
