A Summary on Porter's Five Forces Model

Updated on July 10, 2012

Businesses are always looking for tools to measure operational effectiveness. The Porter’s Five Forces framework is on such analysis or development review tactic. Michael E. Porter, from the Harvard Company Institution, developed the Five Forces model in 1979. His procedure identifies five specific influences that touch every organization or industry: barriers to entrance, supplier power, threat of substitutes, purchasing power and rivalry. Porter's five forces attempt to clarify the different situations organizations may experience when operating in a market. Each force features specific aspects businesses have to defeat or prepare for when operating within their environment.

Porter's five forces typically list barriers to entrance as its first business influence. These barriers are the preliminary obstacles organizations have to defeat when starting operations or getting into brand-new markets. Typical barriers or hurdles can include higher operating expenses, increased costs to acquire resources, restricted accessibility to business inputs, government laws, or decreases in labor supply. Conquering the barriers to entrance can lead businesses to the next of Porter’s five forces, supplier power.

Supplier power occurs when vendors that supply inputs hold a competitive advantage over production organizations that require inputs to develop products. Vendors may concentrate their power by placing high volume order requirements on resources, restrict access to less expensive replacement resources, withhold accessibility to specific resources or high-quality resources to manufacturers. Porter entwines vendor power with the threat of substitutes in his five forces model.

Threat of substitutes is a concept where business competition pits high-quality resources or goods with less expensive resources or goods. Replacement or substitute goods are the products companies and consumers purchase when the initial good is not available or too costly to acquire. The price of resources and consumer reaction to substitute goods are the main threats against high top quality, first-class items. A consumer's potential to acquire substitute resources or goods can result in consumer purchasing power as the next of Porter’s five forces.

All businesses are subject to the individual purchasing power of consumers, including organizations. Porter’s five forces dictate that buyer details, cost sensitiveness, brand identification, and bargaining influence are all essential parts of consumer purchasing power. Numerous consumers may be unaware of the power they have over businesses in a free market economy. Companies will definitely make alternative products based on the reaction from purchasing power and also the response to changes in requested services. This consumer influence results in Porter’s final five forces component: rivalry.

Rivalry represents the competition among businesses for customers. Organizations compete against each other to gain the highest revenues and incomes, along with acquiring the greatest possible market share. Porter recognizes the rivalry force as the driving influence behind his five forces model. Porter deems this so as businesses should compete in a free market that allows for the best playing field where a company can obtain and retain capital. Without competitors, organizations may or may not acquire sufficient profit, being dependent on the reaction of consumers to the supplied goods and services.
