Final answer:
You assign different costs to a single resource using the resource information dialogue box when the resource is allocated to multiple tasks with distinct associated costs or when the resource's skill set influences the costs for different types of tasks/tasks with varying complexities.
Step-by-step explanation:
You assign different costs to a single resource using the resource information dialogue box when the resource is allocated to multiple tasks with distinct associated costs. For example, if you have a resource that is used for both administrative tasks and technical tasks, you can assign different costs to reflect the different levels of expertise required for each type of task.
Additionally, you may assign different costs to a resource when the resource's skill set influences the costs for different types of tasks/tasks with varying complexities. For instance, if you have a resource with advanced skills in a certain area, their rate may be higher when assigned to more complex tasks.
In summary, the resource information dialogue box is used to assign different costs to a single resource when there are multiple tasks with distinct costs or when the resource's skill set affects the costs for different tasks.
