I am trying to get across to my leadership the harm in attempting to do FVA on only one month of the demand plan. Our demand plans are typically 24 months long with monthly increments. What they are attempting to do is evaluate the effectiveness of a demand planner by looking at the systemically generated statistical forecast and then comparing it to whatever the statistical forecast became with demand planner modifications to the algorithm parameters. This is done only by looking at the next month of the demand plan. Do you have any white papers or comments in relation to how long the study should be?
