    The sales forecast is a prediction of a business's unit and dollars sales for some future

    period of time, up to several years or more. These forecasts are generally based primarily

    on recent sales trends, competitive developments, and economic trends in the industry,region, and/or nation in which the organization conducts business.Sales forecastingis

    management's primary tool for predicting the volume of attainable sales. Therefore, thewhole budget process hinges on an accurate, timely sales forecast.

    These technical projections of likely customer demand for specific products, goods, orservices for a specific company within a specific time horizon are made in conjunction with

    basic marketing principles. For example, sales forecasts are often viewed within the contextof total market potential, which can be understood as a projection of total potential sales for

    all companies. Market potential relates to the total capacity of the market to absorb the

    entire output of a specific industry. On the other hand, sales potential is the ability of themarket to absorb or purchase the output from a single firm.

    APPROACHES TO FORECASTING.

    BOTTOM-UP FORECASTING. Analysts using this methodology divide the market into

    segments, and then separately calculate the demand in each segment. Typically, analysts

    use sales force composites, industry surveys, and intention-to-buy surveys to collect data.They aggregate the segments to arrive at a total sales forecast. Bottom-up forecasting may

    not be simple because of complications with the accuracy of the data submitted. Theusefulness of the data is contingent upon honest and complete answers from customers,and on the importance and priority given to a survey by the sales staff.

    TOP-DOWN FORECASTING. This is the method most widely used for industrial

    applications. Management first estimates the sales potential, then develops sales quotas,and finally constructs a sales forecast. Problems arise with this method, however, when theunderlying assumptions of the past are no longer applicable. The correlation between

    economic variables and quantity demanded may change or weaken over time.These two forecasting methods encompass a number of methodologies which can be dividedinto three general categories:qualitative, times-series analysis andregression, and causal.

    QUALITATIVE METHODS. Qualitative methods rely on non-statistical methods of derivinga sales forecast. A company solicits the opinion or judgment of sales executives, a panel ofexperts, the sales force, the sales division supervisors, and/or outside expert consultants.Qualitative methods are judgmental composites of expected sales. These methods are often

    preferred in the following instances: 1) when the variables which influence consumer buyinghabits have changed; 2) when current data is not available; 3) when none of the qualitativemethods work well in a specific situation; 4) when the planning horizon is too far for the

    standard quantitative methods; and 5) when the data has not yet factored in technological

    breakthroughs taking place or forthcoming.The Probability Assessment Method (PAM) forecasts sales volume by utilizing in-houseexpert opinion that provides probabilities between one and 99 percent, plus and minus, on

    certain target volumes. Analysts translate these estimates into acumulativeprobabilitycurve by plotting the volumes by the probability assigned to them. They use this curve to

    aid in forecasting.

    TIME-SERIES ANALYSIS AND PROJECTION. Trend projection techniques may be most

    appropriate in situations where the forecaster is able toinfer, from the past behavior of a

    variable, something about its future impact on sales. Forecasters look for trends that formidentifiable patterns which recur with predictive frequency. Seasonal variations and cyclicalpatterns form more obvious trends, while random variables make projection more complex.

    While time-series methods do not explicitly account for causal relationships between a

    variable and other factors, analysts find the emergent historical patterns useful in making

    forecasts. Analysts typically use time series for new product forecasts, particularly in theintermediate and long-term. The data required varies with each technique. A good rule of

    thumb is a minimum of five years' annual data. A complete history is very helpful.

    CAUSAL METHODS. When analysts find a cause-effect relationship between a variable andsales, a causal model may provide better forecasts than those generated by other

    techniques. Life-cycle analysis forecasts new product growth rates based on analysts'projections of the phases of product acceptance by various groupsinnovators, early

    adapters, early majority, late majority, and laggards. Typically, this method is used to

    forecast new product sales.. It is often necessary to do market surveys to establish thecause-effect relationships.

    THE PRODUCTION BUDGET. Both small and large businesses construct their productionbudgets within limitations of production,warehousing, delivery, and service capabilities.Subsequently, a company attempts to schedule production at maximum efficiency. By

    anticipating the variations in monthly sales, management can keep production at levels

    sufficient to provide adequate supply. Labor costs generally comprise the greatest single

    production cost. Therefore, management may adjust labor hours to production schedules.Production levels remain rather constant if current inventory is sufficient to meet increases

    in sales. If management expects an increase, it may build inventories during the firstquarter of the budget, and sell them down to planned levels during the remaining threequarters. From the production budget, a company estimates the mix of materials, labor, and

    production overhead needed to meet planned production levels
