Following strong initial uptake, ABC lost ground in the 1990s compared to alternative metrics, such as Kaplan's balanced scorecard and economic value added.An independent 2008 report concluded that manually driven ABC was an inefficient use of resources: it was expensive and difficult to implement for small gains, and a poor value, and that alternative methods should be used.

An ABC analysis provides a mechanism for identifying items that will have a significant impact on overall inventory cost, [1] while also providing a mechanism for identifying different categories of stock that will require different management and controls. The ABC analysis suggests that inventories of an organization are not of equal value. [2]
To the ABC model, Seligman adds "D" (disputation) and E (energization). Disputation centers on generating counter-evidence to any of the following: the negative beliefs in general, the causes of the event, or the implications. D also means reminding oneself of any potential usefulness of moving on from the adversity.
ABC methods bypass the evaluation of the likelihood function. In this way, ABC methods widen the realm of models for which statistical inference can be considered. ABC methods are mathematically well-founded, but they inevitably make assumptions and approximations whose impact needs to be carefully assessed.
Companies may be moved to adopt ABC by a need to improve costing accuracy, that is, understand better the true costs and profitability of individual products, services, or initiatives. ABC gets closer to true costs in these areas by turning many costs that standard cost accounting views as indirect costs essentially into direct costs.
An influential model of attitude is the multi-component model, where attitudes are evaluations of an object that have affective (relating to moods and feelings), behavioral, and cognitive components (the ABC model). [29] The affective component of attitudes refers to feelings or emotions linked to an attitude object.
In the ABC algorithm, the first half of the swarm consists of employed bees, and the second half constitutes the onlooker bees. The number of employed bees or the onlooker bees is equal to the number of solutions in the swarm. The ABC generates a randomly distributed initial population of SN solutions (food sources), where SN denotes the swarm ...
A particular method of applying the ABC method [24] assigns "A" to tasks to be done within a day, "B" a week, and "C" a month. To prioritize a daily task list, one either records the tasks in the order of highest priority , or assigns them a number after they are listed ("1" for highest priority, "2" for second highest priority, etc.) which ...
