To get a more accurate look at productivity in setting a standard, extend the process to encompass a full year's worth of productivity to get the standard rate. 5. Use the standard to calculate percent of productivity of later periods by calculating the productivity for that period using the set process used for the standard. Multiply the new productivity period percentage by the standard percentage to get the total productivity percentage based on the standard baseline. Productivity records.
