Changeover Time Reduction through the SMED methodology has found its application across various industries, including automotive, aerospace, food and beverage, and electronics manufacturing, where the need for rapid response to market demands and customization is pronounced. This methodology is particularly effective during the design and implementation phases of manufacturing processes, especially when a company introduces new products or variations. Typically, a cross-functional team involving engineers, operators, and production managers initiates the changeover time reduction initiative, ensuring that diverse perspectives are captured to identify inefficiencies in the process. In practice, this involves detailed mapping of each step in the changeover, allowing teams to distinguish between internal tasks that require the machine to be stopped and external tasks that can be executed while the machine operates. Sources of inefficiencies may emerge from unnecessary adjustments or waiting times, which can be systematically addressed. Industries employing this methodology often report an improvement in production cycle times, enabling them to optimize resource allocation and enhance operational resilience. As a result, businesses can achieve heightened competitiveness by promoting just-in-time production philosophies, leading to more responsive supply chains and improved customer satisfaction.

Die wichtigsten Schritte dieser Methodik

  1. Identify and map out the entire changeover process in detail.
  2. Distinguish between internal and external tasks involved in the changeover.
  3. Convert as many internal tasks as possible to external tasks.
  4. Eliminate non-value-added activities from the changeover process.
  5. Standardize and document procedures for the modified changeover process.
  6. Train operators on the new changeover procedures to ensure consistency.
  7. Implement the new changeover process and monitor its performance.
  8. Continuously seek feedback and make incremental improvements to the process.

Profi-Tipps

  • Implement a detailed time study of each changeover step using video analysis to identify non-value-added activities.
  • Collaborate with cross-functional teams, including operators and engineers, to develop standardized work procedures that maximize external setup tasks.
  • Utilize visual management tools, such as control charts and scoreboards, to continuously track and improve changeover performance metrics.
