I wanted to acknowledge a factual error in my post of April 24 (Oh Canada – Is MRP the Answer?) regarding the use of a multiplier in the new MRP system championed by the CPRS. The system does not currently use a multiplier as Rachel Douglas, a member of the CPRS Measurement Committee, points out in her comment to the post. Thank you Rachel. Good news and a good decision by the Committee.
In my defense, the presentation from the CPRS on the MRP I saw dated March 2, 2006 clearly called for the use of the multiplier. I'm glad this was changed prior to the official launch on April 20.
I stand by the rest of my comments including the misuse of "ROI" in describing the MRP metric.
