BUS501: Strategic Management

This measures the ease with which buyers can switch to another product that does the same thing, such as using aluminum cans rather than glass or plastic bottles to package a beverage. The ease of switching depends on what costs would be involved (e.g., while it may be easy to sell Coke or Pepsi in bottles or cans, transferring all your data to a new database system and retraining staff could be expensive) and how similar customers perceive the alternatives to be. Substitute products are goods or services from outside a given industry that perform similar or the same functions as a product that the industry produces. For example, as a sugar substitute, NutraSweet places an upper limit on sugar manufacturers' prices – NutraSweet and sugar perform the same function but with different characteristics.

Other product substitutes include fax machines instead of overnight deliveries, plastic containers rather than glass jars, and tea substituted for coffee. Recently, firms have introduced to the market several low-alcohol fruit-flavored drinks that many customers substitute for beer. For example, Smirnoff's Ice was introduced with substantial advertising of the type often used for beer. Other firms have introduced lemonade with 5% alcohol (e.g., Doc Otis Hard Lemon) and tea and lemon combinations with alcohol (e.g., BoDean's Twisted Tea). These products are increasing in popularity, especially among younger people, and, as product substitutes, have the potential to reduce overall sales of beer.

In general, product substitutes present a strong threat to a firm when customers face few, if any, switching costs and when the substitute product's price is lower or its quality and performance capabilities are equal to or greater than those of the competing product. Differentiating a product along dimensions that customers value (such as price, quality, service after the sale, and location) reduces a substitute's attractiveness.
