MANAGING SALES INFORMATION “Our charge is to design, build, and implement decision support systems that help our field and marketing managers make business decisions. ” Dan Mc.

FORECASTING MARKET DEMAND A marketing decision support system (MDSS) is an ongoing, future-oriented structure designed to generate, process, store, and later retrieve information to aid decision making in an organization’s marketing program. It involves problem-solving technology composed of people, knowledge, software, and hardware “wired” into the sales management process. Copyright © 2001 by Harcourt, Inc. All rights reserved.
USES OF SALES FORECASTS A sales forecast is the estimated dollar or unit sales for a specific future time period based on a proposed marketing plan and an assumed market environment. Copyright © 2001 by Harcourt, Inc. All rights reserved.
A sales forecast is important for at least five reasons: 1. A sales forecast becomes a basis for setting and maintaining a production schedule – manufacturing. 2. It determines the quantity and timing of needs for labor, equipment, tools, parts, and raw materials – purchasing, personnel. 3. It influences the amount of borrowed capital needed to finance the production and the necessary cash flow to operate the business – controller. 4. It provides a basis for sales quota assignments to various segments of the sales force – sales management. 5. It is the overall base that determines the company’s business and marketing plans, which are further broken down into specific goals – marketing officer. Copyright © 2001 by Harcourt, Inc.

THE FORECASTING PROCESS The forecasting process refers to a series of procedures used to forecast. Copyright © 2001 by Harcourt, Inc. All rights reserved.
A market factor is an item or element that (1) exists in a market, (2) may be measured quantitatively, and (3) is related to the demand for a product or service. A market index is simply a market factor expressed as a percentage relative to some base figure. Copyright © 2001 by Harcourt, Inc. All rights reserved.

Industry sales forecast, or market potential, is the estimated sales for all sellers. Company sales potential is the maximum estimated or potential sales the company may reach in a defined time period under given conditions. The company’s share of the estimated sales for an entire industry is referred to as market share. Copyright © 2001 by Harcourt, Inc. All rights reserved.
SALES FORECASTING METHODS Two categories of sales forecasting methods exist: • Survey methods are qualitative and include executive opinion, sales force composite, and customer’s intention surveys. • Mathematical methods are test markets, market factors, naïve models, trend analysis, and correlation analysis.

SURVEY FORECASTING METHODS Four basic survey methods are • Executive Opinion • Sales Force Composite • User’s Expectations • Build-to-Order Copyright © 2001 by Harcourt, Inc. All rights reserved.
Executive Opinion Executive forecasting is done in two ways: 1. By one seasoned individual (usually in a small company). 2. By a group of individuals, sometimes called a “jury of executive opinion. ” Copyright © 2001 by Harcourt, Inc. All rights reserved.
The group approach uses two methods: 1. Key executives submit the independent estimates without discussion, and these are averaged into one forecast by the chief executive. 2. The group meets, each person presents separate estimates, differences are resolved, and a consensus is reached. Copyright © 2001 by Harcourt, Inc. All rights reserved.
Delphi Method Administering a series of questionnaires to panels of experts. Copyright © 2001 by Harcourt, Inc. All rights reserved.
Sales Force Composite Obtaining the opinions of sales personnel concerning future sales. Copyright © 2001 by Harcourt, Inc. All rights reserved.
User’s Expectations Consumer and industrial companies often poll their actual or potential customers. Copyright © 2001 by Harcourt, Inc. All rights reserved.
Build-to-Order Companies build final products only after firm orders are placed. Copyright © 2001 by Harcourt, Inc. All rights reserved.
MATHEMATICAL FORECASTING METHODS Test markets are a popular method of measuring consumer acceptance of new products. Copyright © 2001 by Harcourt, Inc. All rights reserved.

Time Series Projections Time series methods use chronologically ordered raw data. Copyright © 2001 by Harcourt, Inc. All rights reserved.
Classical approach to time series analysis: • The trend component. • The seasonal component. • The cyclical component. • The erratic component. Copyright © 2001 by Harcourt, Inc. All rights reserved.
Naïve Method This Year’s Sales Next Year’s Sales = This Year’s Sales X Last Year’s Sales Copyright © 2001 by Harcourt, Inc. All rights reserved.
Moving Average Moving averages are used to allow for marketplace factors changing at different rates and at different times. Copyright © 2001 by Harcourt, Inc. All rights reserved.
TABLE 5. 1 EXAMPLE OF MOVING-AVERAGE FORECAST PERIOD SALES VOLUME SALES FOR THREE-YEAR PERIOD MOVING AVERAGE 1 200 2 250 3 300 750 4 350 900 300 5 450 1100 ( 3) = 366. 6 6 ? Period 6 Forecast = 366. 6 Copyright © 2001 by Harcourt, Inc. All rights reserved.
Exponential Smoothing Exponential smoothing is similar to the movingaverage forecasting method. It allows consideration of all past data, but less weight is placed on data as it ages. Next Year’s Sales = a (This Year’s Sales) + (1 -a) (This Year’s Forecast) Copyright © 2001 by Harcourt, Inc. All rights reserved.
Trend Projections – Least Squares Eyeball fitting is simply a plot of the data with a line drawn through them that the forecaster feels most accurately fits the linear trend of the data. Copyright © 2001 by Harcourt, Inc. All rights reserved.

THE BOTTOM LINE Because of the growing trend in business to centralize data collections, the job of forecasting has become an integral part of a firm’s marketing decision support system (MDSS). A sales forecast is the estimated dollar or unit sales for a specific future period based on a proposed marketing plan and an assumed market environment. Firms know sales forecasting is never 100 percent correct. Two categories of sales forecasting methods are survey methods and mathematical methods. Because the sales forecast has a major impact on the company, the top executives give final approval. To create a sales forecast, sales managers should know how to use a computer.
