Cost Estimating Relationship (CER) – CERs are mathematical expressions of varying degrees of complexity expressing cost as a function of one or more cost-driving variables. The relationship may utilize cost-to-cost variables, such as manufacturing hours to quality assurance hours, or cost-to-noncost variables, such as engineering hours to the number of engineering drawings.
