Supply Chain Risk: High-risk strategies often involve dependency on a single source, lack of flexibility, and vulnerability to disruptions.

Single Sourcing: Relying on a single supplier for a high-profit product increases risk because any disruption (e.g., natural disasters, financial issues, or quality problems) at that supplier can severely impact the company's profitability and operations.

Comparative Analysis:

Outsourcing Unsuitable Products: This can also be risky but generally not as impactful as single sourcing high-profit items.

Multiple Sources for Disruptive Products: Reduces risk by ensuring alternatives are available.

Internal Manufacturing for High IP Products: Protects intellectual property and ensures control over production, generally reducing risk.

Conclusion: Single sourcing a product that generates the highest profit increases overall supply chain risk the most due to the potential for significant disruption and financial impact.
