Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is sales forecasting?

    Model answer

    Sales forecasting is the process of predicting the level of future sales over a stated period. Forecasts are built from past sales records and from judgement about market conditions.

  2. 2

    Why does a business forecast its sales before setting a budget?

    Model answer

    The sales forecast fixes the expected revenue that every other budget depends on. Production, staffing and cash budgets are all built from that figure.

  3. 3

    How does sales forecasting help operations managers?

    Model answer

    A forecast tells operations how much output and stock will be needed. Capacity, raw materials and shift patterns can then be arranged in advance.

  4. 4

    How does sales forecasting help a business manage its cash?

    Model answer

    A sales forecast shows when money from customers is likely to arrive. Managers can arrange an overdraft in advance of a predicted shortfall.

  5. 5

    Explain the difference between quantitative and qualitative sales forecasting.

    Model answer

    Sales forecasting includes quantitative techniques that work from numerical sales records. Qualitative techniques work instead from expert judgement and opinion about the future.

  6. 6

    Name two quantitative forecasting techniques.

    Model answer

    Time-series analysis using moving averages is one quantitative technique. Extrapolation of a past trend line is a second.
