Hi,

friend of mine has a Specific problem. He wants MS PROJECT. I will show you this problem with MS PROJECT 2016!

Project has one Task:

Resources are:

As you can see there are Workers with 800% capacity, Laborers with 200% capacity, and Crane and Concrete mixer with 100% capacity.

Workers are supposed to work 300 hours, Laborers 50 hours, Crane 10 hours, and Concrete mixer  20 hours.

Duration of this Task should be calculated by MS PROJECT using workers. SO I will assign Workers to the Task, and I will put 800% for Units, and 300 hours to get Duration:

and I will get:

Now I want to assign remaining Resources like this:

• Laborers 200% 50 hours
• Crane 100 % 10 hours
• Concrete mixer 100% 20 hours

but I want to spread the work during all days of Duration.

First I will assign them as-is:

and I will get:

As you can see, I didn’t get what I wanted. Laborers will work only fist four days, Crane only first two days, and Concrete mixer only first three days. What Can I do? Well, before assign those resources I will switch Task to the Fixed duration mode:

Now I am going to assign those resources in the same way:

Finally, I will get:

As you can see, all resources are used all days (Duration days). Of course they will not spend same amount of hours, as expected.

To conclude, if you want to calculate duration according to one Resource, and then spread the work through duration for rest Resources, follow this steps:

1. Use fixed units or Fixed work and assign first resource. Duration will be calculated.
2. Switch the Task to Fixed Duration Type
3. Assign remaining resources to Task.

Regards.
