Any business while preparing a rolling forecast model must decide whether they want to update the forecast data weekly, monthly or quarterly, as analyzing the actual results with forecast and then updating the next period forecast is a time consuming and daunting task. In most cases, this is prepared over a period of twelve months.

Also, the forecasted numbers must not come from someone who does not understand the complete process and might give some forecasted figures impossible to achieve.
