The following appeared in a memorandum issued by the strategic planning department at Omni Inc.
"Mesa Foods, a manufacturer of snack foods that currently markets its products within a relatively small region of the country, has strong growth potential. Mesa enjoyed a 20 percent increase in profits last year(3,4), and its best-selling product, Diabolique Salsa, has had increased sales over each of the past three years(2). Since Omni Inc. is interested in reaching 14-to-25 year olds, the age group that consumes the most snack food(1), we should buy Mesa Foods(5), and concentrate in particular on marketing Diabolique Salsa throughout the country."
（１）The assumption that Mesa's snack foods appeal to 14-to-25-year olds is open to doubt.
（２）The increased sales of Diabolique Salsa in the region where it is sold does not indicate that it will also gain success nationwide.
（３）We do not know how large is the snack food market in the region where Mesa’s products are sold, thus the 20% increase may be insignificant.
（４）Last year's 20% increase in Mesa's profits may be an aberration, no evidence could indicate that this trend will continue in the future.
（５）We do not know the profitability of other food products of Mesa Food, thus could not evaluate if Omni should buy the entire company.
