_Force

The term force is c. 1300, "physical strength," from Old French force "force, strength; courage, fortitude; violence, power, compulsion" (12c.), from Vulgar Latin *fortia (source also of Old Spanish forzo, Spanish fuerza, Italian forza), noun use of neuter plural of Latin fortis "strong, mighty; firm, steadfast; brave, bold."

Michael Porter described the five forces in the competitive environment. The five forces are; competitive rivalry, supplier power, buyer power, threat of substitution, and threat of new entry. Number, quality, switching barriers, customer loyalty, uniqueness, substitution, cost of change, differences, size, price sensitivity, specialist knowledge, economies of scale, technology protection, and barriers to entry. May the forth be with you.
