Good stress, also known in the scientific community as eustress, may be just the thing you need to get job done at work. âThink about a deadline: Itâs staring you in the face, and itâs going to stimulate your behavior to really manage the situation effectively, rapidly, and more productively,â says Dr. Shelton.
Direct costs can include fixed and variable costs. Direct fixed costs can be easily traced to cost objects and do not vary with the level of production. Direct variable costs vary with production levels. For example, suppose the engineering department of a company is producing a new technology device.
Variable costs change according to the quantity of goods produced; fixed costs are independent of the quantity of goods being produced. Differentiate fixed costs and variable costs. 1  Total cost is the sum of fixed and variable costs.  Variable costs change according to the quantity of a good or service being produced. The amount of materials and labor that is needed for to make a good increases in direct proportion to the number of goods produced.
