What is 6S?

6S is a system designed to reduce waste and optimize productivity by maintaining an orderly workplace and using visual cues to achieve more consistent operational results. The implementation of 6S helps “clean up” and organize the workplace within its existing configuration, streamlining activities and improving overall efficiency.

The 6S Framework

1. Seiri (Sort)

Remove unnecessary items from each area to create a clutter-free environment. Sorting ensures that only essential tools, materials, and items remain, which leads to a more organized workspace.

2. Seiton (Straighten)

Organize and identify storage for efficient use. This step involves arranging necessary items so that they are easy to access and retrieve, leading to faster and smoother workflow processes.

3. Seiso (Shine)

Clean and inspect each area regularly. Keeping the workspace clean and tidy prevents the accumulation of dirt and debris, contributing to a healthier and safer environment for workers.

4. Seiketsu (Standardize)

Incorporate 5S into standard operating procedures. Standardizing processes ensures that the first three S's—Sort, Straighten, and Shine—become routine practices within the workplace.

5. Shitsuke (Sustain)

Assign responsibility, track progress, and continue the cycle. Sustaining the gains made from 5S requires ongoing commitment from everyone, ensuring that improvements are maintained and built upon over time.

6. Safety

Safety is the sixth S and is an ongoing practice that should be embedded in both the workplace culture and employees' mindsets. Reminding workers to stay safe and protect themselves through visual cues like wall signs ensures that safety becomes part of everyday operations.

Why is 6S Important in Manufacturing?

Though first developed for the automotive industry, 6S is now widely considered an essential element of any lean manufacturing program across industries. The system goes beyond simple cleaning and organization; it promotes a mindset that encourages operators to improve their work environment and reduce waste (or "muda").

Adhering to 6S standards is the foundation of Total Productive Maintenance (TPM) and is an integral part of the Toyota Production System (TPS). It provides a stable platform from which Kaizen (continuous improvement) activities can be launched, fostering a culture of efficiency and improvement.

Key Benefits of 6S in Manufacturing

By incorporating 6S into daily routines, businesses can enjoy a variety of benefits, including:

  • Improved Safety: Fewer hazards, cleaner environments, and safer working conditions.
  • Higher Equipment Availability: Preventive maintenance practices ensure that machinery is in optimal condition.
  • Lower Defect Rates: A more organized and visually controlled environment reduces errors and defects.
  • Reduced Costs: Efficient use of space and materials minimizes unnecessary expenses.
  • Increased Agility and Flexibility: Well-organized processes make it easier to adapt to changes or shifts in production.
  • Improved Employee Morale: A clean, safe, and organized workspace leads to higher job satisfaction.
  • Better Asset Utilization: 6S promotes the efficient use of resources, ensuring that assets are used effectively.
  • Enhanced Enterprise Image: A cleaner, safer, and more organized workspace improves the perception of the company among customers, suppliers, employees, and management.

 

The bottom line: 6S is a low-investment, high-impact lean manufacturing tool that centers on people. It engages operators in taking ownership of their workspace and helps instill a culture of quality, productivity, and continuous improvement. By using 6S, businesses can not only improve safety and efficiency but also enhance their overall operational performance, leading to long-term success.
