How does one realistically assess the viability of a business? This is perhaps the most critical business assessment a manager must make. Many are taught from an early age to not give up, even in the face of adversity. Certainly there are countless stories of businesses that struggled to survive their infancy, but went on to become highly successful. But, it is equally important to identify business models that simply will not work. The Nature Of CostsManagerial accounting methods provide techniques for evaluating the viability and ability to grow or “scale” a business. These techniques are called cost-volume-profit analysis (CVP). CVP fundamentally depends upon developing an understanding of the nature and behavior of an entity’s costs. To understand how a business is going to perform over time and with shifts in volume, it is imperative to first consider the cost structure of the business. This requires drilling down into the specific types of costs that are to be incurred and trying to understand their unique attributes. Variable costs will vary in direct proportion to changes in the level of an activity. For example, direct material, direct labor, sales commissions, and so on, may be expected to increase with each additional unit of output. The opposite of variable costs are fixed costs. Fixed costs do not fluctuate with changes in the level of activity. Examples include administrative salaries, rents, and property taxes. Variable Cost ExampleThe data are plotted on the following graphs. One graph reveals that total variable cost increases in a linear fashion. The slope of the line is constant. When plotted on a “per unit” basis, the variable cost is constant at $11 per unit. Increases in volume do not change the per unit cost. The activity base is the item or event that causes the incurrence of a variable cost. It is easy to think of the activity base in terms of units produced, but it can be more than that. Activity can relate to labor hours worked, units sold, customers processed, or other such “cost drivers.” For instance, a dentist uses a new pair of disposable gloves for each patient seen, no matter how many teeth are being filled. Therefore, disposable gloves are variable and key on patient count. But, the material used for fillings is a variable that is tied to the number of decayed teeth that are repaired. Each variable cost must be considered independently and with careful attention to what activity drives the cost. Fixed Cost ExampleCost ImplicationThe nature of a specific business will have a lot to do with defining its inherent fixed cost structure. Airlines have historically been burdened with high fixed costs related to gates, maintenance, reservation systems, and aircraft. Airlines struggle during lean years because they are unable to cover fixed costs. During boom years, these same companies can be extremely profitable, because many costs do not rise with increases in volume. Basically, there is not much cost difference in flying a plane empty or full. Software companies have a big investment in product development, but very little cost in reproducing multiple electronic copies of the finished product. Their variable costs are low. Other businesses have attempted to avoid fixed costs so that they can maintain a more stable stream of income relative to sales. For example, a computer company might outsource its tech support. Rather than having a fixed staff that is either idle or overloaded at any point in time, it pays an independent support company a per-call fee. The effect is to transform the organization’s fixed costs to variable and better insulate the bottom line from fluctuations brought about by the related ability to cover or not cover the fixed costs of operations. Every business is unique, and a savvy business person will be careful to understand cost structure. For a long time, the trend for many businesses was toward increased fixed costs. Some of this was the result of increased investment in robotics and technology. However, those components have become more affordable, and there is now more outsourcing, elimination of employee benefits, and so forth. These activities suggest attempts to structure businesses with a definitive margin that scales up and down with changes in the level of business activity. Economies Of ScaleThe key point is to note that both fixed and variable costs maintain their characteristics over some particular range of activity. It is important to understand the full implications of this observation in managing a business. Adopting a business strategy that results in operating levels outside of the relevant range can significantly upset business results via significant deviations between actual and expected performance. Dialing In The Business ModelConsider that some fixed costs are committed fixed costs arising from an organization’s commitment to engage in operations. These elements include such items as depreciation, rent, insurance, property taxes, and the like. These costs are not easily adjusted with changes in business activity. On the other hand, discretionary fixed costs originate from top management’s yearly spending decisions; proper planning can result in avoidance of these costs if cutbacks become necessary or desirable. Examples of discretionary fixed costs include advertising, employee training, and so forth. Committed fixed costs relate to the desired long-run positioning of the firm; whereas, discretionary fixed costs have a short-term orientation. Committed fixed costs are important because they cannot be avoided in lean times; discretionary fixed costs can be altered with proper planning. Variable costs are also subject to adjustment. In the electronic parts example, it was illustrated how such costs can vary based on quantities ordered. Perhaps one might order and store large quantities of the part for use in future periods. A subsequent chapter shows how to calculate economic order quantities that take into account carrying and ordering costs in balancing these important considerations. Even direct labor cost can be subject to adjustment for overtime premiums, based on whether or not overtime is worked. It may or may not make sense to meet customer demand by ramping up production when overtime premiums must be paid. The interplay between all of the different costs emphasizes the importance of good planning. The trick is to synchronize operations so that the benefits of each fixed cost are maximized, and variable cost patterns are established in the most economic position. All of this must be weighed against revenue opportunities; one must be able to sell what is produced.

For example, you may work with a project manager to see how much each stage of workflow costs before the task is completed.
What are the methods of determining cost behaviour?Answer: Four common approaches are used to estimate fixed and variable costs:. Account analysis.. High-low method.. Scattergraph method.. Regression analysis.. What are the 3 most common cost behavior classifications?Answer: The three basic cost behavior patterns are known as variable, fixed, and mixed.
What do you mean by cost behavior how does it influence managerial decision making?Cost behavior is the manner in which expenses are impacted by changes in business activity. A business manager should be aware of cost behaviors when constructing the annual budget, to anticipate whether any costs will spike or decline.
