a. Top management has independently set a $300,000 overall monthly sales goal for the company. Roll up the individual product forecasts and compare them with the family data. Use a spreadsheet and the family forecasts to revise the individual item forecasts (in both dollars and units).
b. Roll up the family forecasts to the top level, compare these to the overall forecasts, and roll the forecasts back down to families and to individual unit forecasts (dollars units).
c. Suppose a major customer order has just been received for 10 units of product J. This order wasn’t expected and it in addition to any other forecasts for product J. The company still wants to plan a total monthly sales volume of $300,000. Use the family forecasts (revised) to roll the forecasts to and down to get revised individual product forecasts.
