Yes, you could. However, some substantial elements of price of conformance, like costs for quality control activities (inspections and testing) and control of monitoring and measuring devices (calibration and maintenance) I think are lacking in the data.
You could also make a distinction between costs that are dependent on the sales (e.g. NCR's, testing, inspections) and costs that are (more) independent of the sales (e.g. Quality Audits, calibration, maintenance). For the first a presentation in percentages is the most valuable, for the latter a nominal presentation. E.g. you have to calibrate an instument commonly within a specified time period irrespective of the use frequency. Unless you can put it out of use, because you have more than one instrument or you can demonstrate that you can safetly reduce the calibration frequency these costs are more or less fixed. Such discussions management may have and the graph is helpfull in that.
