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.

In materials management, ABC analysis is an inventory categorisation technique which divides inventory into three categories: 'A' items, with very tight control and accurate records, 'B' items, less tightly controlled and with moderate records, and 'C' items, with the simplest controls possible and minimal records.
As for all statistical methods, a number of assumptions and approximations are inherently required for the application of ABC-based methods to real modeling problems. For example, setting the tolerance parameter ϵ {\displaystyle \epsilon } to zero ensures an exact result, but typically makes computations prohibitively expensive.
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 ...
Artificial bee colony (ABC) algorithm is an optimization technique that simulates the foraging behavior of honey bees, and has been successfully applied to various practical problems [citation needed]. ABC belongs to the group of swarm intelligence algorithms and was proposed by Karaboga in 2005.
A/B testing (also known as bucket testing, split-run testing, or split testing) is a user experience research method. [1] A/B tests consist of a randomized experiment that usually involves two variants (A and B), [ 2 ] [ 3 ] [ 4 ] although the concept can be also extended to multiple variants of the same variable.

ABC scores are linear, so any file, module, class, function or method can be scored. For example, the (vector) ABC score for a module is the sum of the scores of its sub-modules. Scalar ABC scores, however, are non-linear.
