Final answer:
Eli Whitney introduced the concept of interchangeable parts, revolutionizing production by making parts standardized and easily replaceable, expediting machinery production and reducing costs.
Step-by-step explanation:
The person who introduced standardized, interchangeable parts was Eli Whitney. Whitney is best known for inventing the cotton gin, but he also developed the concept of interchangeable parts during the market revolution. This was a significant change from the previous system where items were handcrafted individually, requiring custom-fitting for each replacement part. Eli Whitney's introduction of interchangeable parts allowed for easier and more cost-effective replacement, facilitating more rapid production and ensuring each part was an exact duplicate of others.
