Variables costs are controllable because project managers can implement strategies to lower variable costs such as changing suppliers to reduce the cost of materials.

Some examples of direct costs are materials and direct labor. Indirect costs are costs that are not associated with the production of a firm. Examples of indirect costs include supervisor salaries, indirect labor, and supplies used (Referenceforbusiness).
