Incremental vs. Comprehensive Analysis
The incremental analysis focuses on relevant amounts where the comprehensive analysis requires a vast amount of information. The incremental analysis examines the differences between alternatives where the comprehensive examines the whole picture. Being based on relevancy, the incremental analysis ignores irrelevant amounts while still considering qualitative factors. In comparison, the incremental analysis is considered more about the economic factors than the comprehensive analysis, but is just as effective in decision making.
The comprehensive analysis gathers information from all relevant aspects of the business, including past and present amounts, to evaluate the complete picture. This requires a lot of time to gather all the information and more time to evaluate the information. It is based on reasoning and requires the ability to predict future consequences of decisions being made (Farrell). The comprehensive analysis is primarily used to evaluate the position of the business as a whole compared to industry and competitive information.
On the other hand, the incremental analysis focuses on relevancy for the here and now decisions. It can be used to evaluate for deficiencies in decisions made from the comprehensive analysis. It does not focus on future consequences. It only looks at the relevancy of alternatives now. Any amount considered as irrelevant is ignored.
The incremental analysis examines decision components of revenue (or benefit) differences, cost differences, and cost savings differences between the alternatives (Tanner). It only focuses on the relevant differences in the revenues and costs. This would include opportunity costs (profits or expense increases or decreases). Qualitative factors, such as product quality, employee morale, perception, or customer service, are also considered for effects of each one.
Incremental analysis is useful for special order decisions, limited resource, make or buy product decisions, and sell, scrap, or rebuild decisions. It focuses on the information needed for the current decision that needs to be made. In this way, the incremental analysis is more economical to use than the comprehensive analysis. It saves a manager more time by just focusing on the individual decision criteria.
Special order decisions can use the incremental method to quickly evaluate to determine if it is profitable for the business to do a large order, especially if a discount is included in the revenue of the order. The incremental analysis can be used to allocate limited resources in a more efficient and cost savings manner. Whether to make a product or buy the product to resell can be made more efficient with the incremental analysis without spending a lot of time to determine the profitability of the decision. Decisions on whether to sell, scrap, or buy new equipment is made better with the incremental analysis because it is here and now decisions.
