Industry-level strategy is a corporate strategy that addresses the question "How should we compete in this industry?" As part of the strategie planning process, firms should seek to understand the competitive structure of the industry. A number of years ago, Harvard professor Michael Porter identified five competitive forces that influence planning strategies in a model called Porter's Five Forces. Porter notes that these different forces exert strong influences on an industry's profitability potential over time. Character of the rivalry is a measure of the intensity of competitive behavior between companies in an industry. Industry dynamics and the economic environment can influence rivalry, The threat of new entrants is based on the level of difficulty for entering a market or industry. For example, it's considerably more expensive to begin building automobiles like Tesla than to start a house cleaning service. If new companies can easily enter the market, it might cause increased competition and ultimately lower prices and profits, The threat of substitute products or services also is a competitive force impacting industries. If customers have the opportunity to replace a company's products with goods or services from a competing firm, the company's marketers may have to find a new market, change prices, or compete in other ways to maintain an advantage. McDonald's made what some considered a bold move when the firm announced the launch of its "McCafe," offering upgraded coffee drinks such as lattes, cappuccinos, and mochas-in direct competition with Starbucks and Dunkin' Donuts. The bargaining power of suppliers is another threat impacting industries, as those with more powerful suppliers must charge higher prices or pass along price increases to other members in the supply chain in order to meet the demands of suppliers. A chemical manufacturer selling specialized herbicides to agricultural firms like DuPont might be able to negotiate more favorable pricing because DuPont does not have an alternate supplier for this chemical. Similarly, Procter & Gamble (P&G) may possess a high degree of power when negotiating with retailers who depend on selling popular P&G brands such as Tide, Pampers, and Bounty paper towels in their stores. The bargaining power of customers is another threat because customers may possess greater negotiating leverage to extract price concessions or other favorable terms. As the largest retailer in the world, Walmart has quite a reputation of squeezing its supplier partners to reduce prices in an effort to provide Walmart customers with everyday low prices. This puts pressure on profit margins for these suppliers, and even Walmart knows it. The company recently suggested its suppliers reduce their in-store and online marketing promotions as a way to reduce costs. According to Porter's Industry forces, Is a measure of the intuence that suppliers of parts, materials, and services to firms in an Industry have on the prices of these inputs. the threat of substitute products or services the bargaining power or buyers O the threat of new entrants the bargaining power of supptlers If an organization chooses to make its product or service sufficiently different from competitors' offerings that customers are willing to pay a premium price for it, they are using which type of positioning strategy O Focus O Cost leadership O Niche Differentiation seek fast growth by searching for new market opportunities, encouraging risk taking, and being the first to bring innovative new products to market.
