Past-Sales Analysis
Sales forecasts can be developed on the basis of past sales. Time-series analysisconsists
of breaking down past time series into four components (trend, cycle, seasonal, and
erratic) and projecting these components into the future. Exponential smoothingcon-
sists of projecting the next period’s sales by combining an average of past sales and
the most recent sales, giving more weight to the latter. Statistical demand analysiscon-
sists of measuring the impact level of each of a set of causal factors (e.g., income, mar-
keting expenditures, price) on the sales level. Finally, econometric analysisconsists of
building sets of equations that describe a system and proceeding to fit the parame-
ters statistically.Market-Test Method
Where buyers do not plan their purchases carefully or experts are not available or re-
liable, a direct market test is desirable. A direct market test is especially desirable in
forecasting new-product sales or established product sales in a new distribution chan-
nel or territory.Analyzing
Marketing(^128) Opportunities
1.Three developments make the need for marketing information greater now than
at any time in the past: the rise of global marketing, the new emphasis on buyers’
wants, and the trend toward nonprice competition.
2.To carry out their analysis, planning, implementation, and control responsibilities,
marketing managers need a marketing information system (MIS). The MIS’s role is to
assess the managers’ information needs, develop the needed information, and dis-
tribute that information in a timely manner.
3.An MIS has four components: (a) an internal records system, which includes in-
formation on the order-to-payment cycle and sales reporting systems; (b) a mar-
keting intelligence system, a set of procedures and sources used by managers to
obtain everyday information about pertinent developments in the marketing en-
vironment; (c) a marketing research system that allows for the systematic design,
collection, analysis, and reporting of data and findings relevant to a specific mar-
keting situation; and (d) a computerized marketing decision support system that
helps managers interpret relevant information and turn it into a basis for market-
ing action.
4.Companies can conduct their own marketing research or hire other companies to
do it for them. Good marketing research is characterized by the scientific method,
creativity, multiple research methods, accurate model building, cost–benefit analy-
sis, healthy skepticism, and an ethical focus.
5.The process consists of defining the problem and research objective, developing
the research plan, collecting the information, analyzing the information, and pre-
senting the findings to management. In conducting research, firms must decide
whether to collect their own data or use data that already exist. They must also de-
cide which research approach (observational, focus-group, survey, behavioral data,
or experimental) and which research instrument (questionnaire or mechanical in-
struments) to use. In addition, they must decide on a sampling plan and contact
methods.
6.One major reason for undertaking marketing research is to discover market op-
portunities. Once the research is complete, the company must carefully evaluate
its opportunities and decide which markets to enter. Once in the market, it must
prepare sales forecasts based on estimates of demand.
7.There are two types of demand: market demand and company demand. To esti-
mate current demand, companies attempt to determine total market potential, area
market potential, industry sales, and market share. To estimate future demand,
companies survey buyers’ intentions, solicit their sales force’s input, gather expert
opinions, or engage in market testing. Mathematical models, advanced statistical
techniques, and computerized data collection procedures are essential to all types
of demand and sales forecasting.
