1. The History of Quality Assurance

Early Quality Control (Pre-20th Century)

Middle Ages: Guilds enforced craftsmanship standards for goods.
Industrial Revolution (1800s): Factories introduced basic inspection processes.

Modern QA (20th Century)

1920s: Statistical Quality Control (SQC) emerged in manufacturing.
1950s: W. Edwards Deming pioneered Total Quality Management (TQM) in Japan.
1980s: ISO 9001 standardized global quality benchmarks.

Software QA Evolution (1990s-Present)

1990s: Manual testing dominated early software development.
2000s: Automated testing tools (Selenium, JIRA) revolutionized QA.
