Testing, Quality, and Safety
Making sure designs work
Testing
Testing checks whether a design meets its requirements. Engineers test strength, performance, durability, safety, and reliability under expected and extreme conditions.
Quality control
Quality control means checking products during or after manufacturing to make sure they meet standards. Small defects can become big problems if they are not found early.
Safety first
Safe engineering means thinking about what can go wrong, how likely it is, and how serious the consequences would be.
Testing vocabulary
What does testing help engineers do?
Testing provides evidence about performance.
Correct answer: Check whether requirements are met
What is quality control?
Quality control helps catch defects and maintain standards.
Correct answer: Checking products meet standards
What is reliability?
Reliable designs perform well repeatedly.
Correct answer: How consistently a system works over time.
Why do engineers think about risk?
Risk analysis supports safer designs.
Correct answer: To understand what could go wrong and reduce the chance or impact of failure.
