STEPS OF DEVELOPING A COST ESTIMATING RELATIONSHIP
Firmly speaking, a CER is not a quantitative method. It is a framework for using suitable quantitative methods to quantify a relationship among an independent variable and cost or price. Development of a CER is a 6-step procedure as shown below:
Step1: State (or select) the dependent variable (Y)
Step2: Select the cost driver(s)
Step3: Gather data concerning the relationship among the dependent and independent variables
Step4: Plot the data on a graph
Step5: Choose the relationship which best predicts the dependent variable
Step6: Test the consistency of the cost function
