ACC 406 Chapter 3: Chapter 3 - Cost Behaviour
Document Summary
Cost behaviour is the way costs change as the related activity changes. It represents the foundation on which managerial accounting is built, much like the critical role played by the theoretical pyramid in financial accounting. Knowing how cost change as output changes is essential to planning, controlling and decision making. Cost driver is a causal measurement that causes cost to change. Identifying and managing cost drivers help managers better predict and control costs. Relevant range is a range of output over which the assumed cost relationship is valid for the normal operations of a firm. Limits the cost relationship to the range of operations that the firm normally expects to occur. Ex: looking back at the company"s pervious example if the company were to increase its current production 2 or 3 times, perhaps by adding a second or third shift, one supervisor could not possibly handle all 3 shifts.
