Assigning and tracking two resources with diffrent type in a task
It may be very newbie question. I am using MS Project. I want to know how to track a task with two different resources. How can we calculate man hour or progresses of this task when there are two resources. For example, my task is from civil engineering project and lets say its name is "3rd floor reinforced concrete works". Dont i have to assign "concrete", "steel" and "workers" resources to this task. When i do this, how can i track this activity. Because concrete and steel are "material" type but workers are "work type resources. What do you suggest me in order to track this activity? In a youtube tutorial an expert was saying "use one resource to one task" do not use more resources. Is it true? What should i do?
