An important agile quality strategy, an important quality strategy in general, is to reduce the feedback cycle between obtaining information and validating it. The shorter the feedback cycle the less expensive (on average) it is to address any problems, see Why Agile Testing and Quality Techniques Work later in this article, and the greater the chance that you'll be motivated to make the required change in the first place. Table 1 discusses the impact of the feedback cycle of several agile techniques to give you a better understanding.
The use of disparate impact in this context also has profound constitutional problems. Although proponents of OCR’s Letter may claim it does not compel the use of racial quotas, that’s precisely the outcome produced.
