First-Mover Advantage- The first organization to market with a competitive advantage.
Environmental Scanning- Analysis of events and trends in the market external to the organization.
Organizations use 3 tools to analyze and develop competitive advantage: (1) the Five-Sources Model, (2) the three generic strategies, and (3) value chains.
There are 4 competitive forces that can hurt potential sales: (1) knowledgeable customers pitting rivals against each other, (2) suppliers charging higher prices for supplies, (3) new market entrants stealing capital, and (4) substitute products available to customers.
Five Forces Model
Buyer Power- The ability of buyers to directly impact the price they are willing to pay for an item. Factors include: number of customers, size of orders, difference between competitors, price, and availability of substitute products.
Supplier Power- The ability of suppliers to directly impact the price they are charging for supplies. Factors include: number of suppliers, size of suppliers, uniqueness of services, and availability of substitute products.
Threat of Substitute Products or Services- High when there are many products to choose from and low when there are fewer alternatives to choose from.
Threat of New Entrants- High when it is easy to enter the market and low when there are many entry barriers to entering the market.
Rivalry Among Existing Competitors- High when competition is fierce in a market and low when competition is more complacent.
