Business risks can lower profits or cause losses and are influenced by factors like sales, prices, costs, competition, the economy, and regulations. There are four main types of business risks: physical risks, location risks, human risks, and technology risks. Risks must be identified and prioritized based on their probability of occurrence, such as very likely or small chance. Managing risks involves identifying threats, assessing vulnerabilities, determining expected risks, identifying ways to reduce risks, and prioritizing reductions based on strategy.
