Changeover—the process of switching a line or machine from producing one product to another—may seem routine, but it has a huge impact on efficiency, cost, and competitiveness. Every minute spent preparing machines, adjusting tools, or setting up for the next product is lost production time. During this period, equipment sits idle while labor costs continue, creating one of the most overlooked forms of waste in manufacturing.

In industries such as automotive, electronics, and consumer goods, where frequent product variation is the norm, changeover speed determines flexibility and profitability. A long, inefficient changeover means higher costs, reduced output, and delayed delivery. A fast, well-structured changeover, on the other hand, unlocks the ability to produce smaller batches, respond quickly to market demands, and reduce inventory.

This book demystifies the changeover process and shows you how to:

• Understand the true cost of downtime and setup inefficiencies

• Apply SMED (Single-Minute Exchange of Dies) techniques to drastically cut changeover times

• Identify which steps add value and which can be simplified, standardized, or eliminated

• Build a culture of continuous improvement where operators actively drive setup reduction

• Learn from real-world case studies in manufacturing environments

Whether you’re an operations manager, engineer, or lean practitioner, this practical guide will help you turn changeover from a costly burden into a strategic advantage.
