Federal contractors with 100 or more employees must analyze their total selection process for each job or group of jobs, for adverse impact. See, 42 CFR 60-2-17(b)(2). For that purpose, Office of Federal Contract Compliance Programs (OFCCP) use a tool called the Impact Ratio Analysis (IRA). Additionally, OFCCP uses the IRA to extort money from contractors that purportedly discriminate based on gender, race and/or ethnicity.
