Creating Fixed Duration Task using Task form in MS Project 2019


today I’m going to show you how to use Task Form for creating Tasks from the scratch using MS PROJECT 2019!

First of all, let me crate two brand new Project:


OK. I need John and Mary as Resources, as well:


OK, now the Task Form:


Remember the magic formula, the heart of MS PROJECT which is: Work = Duration * Units

Now, I will create brand new Task for which I want to be Fixe duration, non Effort Driven with 5 days of Duration, but I want John to work 16 hours, and Mary 32 hours:


When I hit OK button I will get:


Wow! This is now what I wanted. So, this must be a bug. But it is not!

Since I put Duration = 5 days, and Duration is fixed, and I did not put Units,MS PROJECT calculate work, no matter of values in Work field like this:

Work = Duration * Units, e.g. work = 5 days (8 house per day e.g 40 hours) * UNITS form Resource sheet (e.g. 100%), and the result is Work = 40 hours * 100% = 40 hours for John and Mary.

But, I want that in this 5 days John work 16 hours and Mary 32. I have two options to get that.

First one is to change hours like this:


and I will get:


Second one is to put right Units when creating a new Task, like this:


and I will get the same result:


MS PROJECT will calculate work according to magic formula, like this:

  • John: Work = Duration * Units, e.g. work = 5 days (8 house per day e.g 40 hours) * UNITS form  (e.g. 40%), and the result is Work = 40 hours * 40% = 16 hours
  • Mary: Work = Duration * Units, e.g. work = 5 days (8 house per day e.g 40 hours) * UNITS form  (e.g. 80%), and the result is Work = 40 hours * 80% = 32 hours

Hope this helps.
