1. Supply Chain: Dependence on a limited number of suppliers can make a business vulnerable to interruptions in supply. Events such as natural disasters, political instability, or supplier bankruptcy can disrupt the supply chain. 2. Technology: Relying on specific technology or software can be risky if there are outages, cyber-attacks, or if the vendor discontinues support. 3. Human Resources: Key personnel risks arise when a business is highly dependent on the expertise of a few individuals. The departure of these individuals can lead to knowledge gaps and operational inefficiencies. 4. Market Conditions: Businesses that rely heavily on specific markets or customer segments may face risks if those markets shrink or undergo significant changes.
