Welcome to the realm of Just-In-Time (JIT) inventory management, a methodology revolutionizing how businesses handle inventory and production processes. This introduction will unveil the concept of JIT, tracing its origins and outlining its foundational principles.

JIT originated in Japan, primarily developed by Toyota in the mid-20th century. It emerged as a response to limited space and resources, focusing on maximizing efficiency and minimizing waste.

At its core, JIT is about having the right amount of inventory, at the right place, and at exactly the right time. It aims to streamline production processes, reduce warehouse storage needs, and minimize costs associated with holding excess inventory.

Basic Principles of JIT

Elimination of Waste: JIT is grounded in the principle of eliminating all forms of waste – whether it’s overproduction, excess inventory, or idle time.
