Lean manufacturing is a philosophy derived from the Toyota Production System aimed at eliminating unnecessary waste in manufacturing. It emphasizes worker safety, efficient movement, and empowering workers with authority and responsibility. By reducing waste, lean manufacturing initiatives enhance efficiency and ultimately create more value for customers through lower costs associated with defects and inefficiencies.

1. What Is Lean Manufacturing?

2. Introduction
• A former president of Raloid Corporation, Ramon
Anthony Jadra has extensive experience in the
aerospace and defense industry. Currently, Ramon
Anthony Jadra is a business consultant at JFive LLC.,
where he counsels third-party vendors, such as
machine shops, on how to implement several lean
manufacturing initiatives.
The lean manufacturing (LM) philosophy originates
from the Toyota Production System (TPS), and it
consists of a method for eliminating unnecessary waste
within a manufacturing system. This waste reduction
leads to a more efficient and cost-effective factory.

3. Lean Manufacturing
• According to the TPS, the production process has to consider the
workers' safety, eliminate any inefficient movement by workers,
and to show trust by giving workers more authority and
responsibility than is normally found within production facilities.
LM initiatives are mainly based on the elimination of waste, and
they aim to remove excesses generated in aspects of the
manufacturing process such as transportation, inventory, motion,
waiting, over-processing, over-production, and product defects.
The initiatives ultimately focus on customer value. Since all the
manufacturing process costs are added into the final product,
with LM initiatives in place customers pay less for defects and
waste, and what they do pay ends up in the product itself.
