1. The History of Industrial Engineering

Early Foundations (1700s-1800s)

1760s: The Industrial Revolution introduced mass production, creating a need for workflow optimization.
1798: Eli Whitney pioneered interchangeable parts, revolutionizing manufacturing.
1881: Frederick Taylor, the “Father of Scientific Management,” developed time-motion studies to improve worker efficiency.

20th Century: Formalization & Growth

1913: Henry Ford’s assembly line applied IE principles to automotive manufacturing.
1940s: World War II accelerated operations research (OR) for logistics and supply chains.
1960s: Computers and automation transformed data-driven decision-making.

Modern Era (2000s-Present)

Lean Manufacturing & Six Sigma became industry standards.
AI, IoT, and Big Data now drive smart factories and Industry 4.0.

Today, Industrial Engineers work in tech, healthcare, logistics, and beyond, shaping the future of work.
