Stress Testing

Stress testing is a rigorous evaluation process designed to determine the stability and reliability of a system, product, or organization by pushing it beyond normal operational capacity. This systematic approach to quality assurance helps identify breaking points, limitations, and potential vulnerabilities before they manifest in real-world situations.

Core Principles

1. Boundary Exploration

   • Testing beyond normal operating parameters
   • Identifying system limitations
   • Establishing failure modes
   • Determining breaking points

2. Risk Assessment

   • Evaluating potential failure scenarios
   • Measuring system resilience
   • Documenting recovery capabilities
   • Analyzing risk management implications

Applications
