Since the 1950s, the 5S system in factory management has been a “secret weapon” to enhance production efficiency. This method quickly spread across modern factories worldwide. In this article, KTG Industrial will share how to apply the 5S system to optimize factory performance, thereby delivering sustainable value for businesses.
Overview of the 5S system in factory management
The 5S system in factory management originated in Japan and was developed in the 1950s as part of the Toyota Production System (TPS). The goal of 5S is to create an organized, clean, and efficient working environment, thereby increasing productivity and reducing waste in the production process.
Initially, this method was applied at Toyota’s manufacturing plants to optimize the workspace. Later, due to its significant impact on increasing productivity and reducing waste, 5S quickly spread to various industries and countries worldwide and became an integral part of modern quality management systems.
Today, 5S is not only limited to the manufacturing sector but is also widely applied in services, healthcare, education, and many organizations globally.
“5S” is an acronym for five Japanese terms that begin with the letter “S”
What does the 5S process include?
The 5S process consists of five steps, corresponding to five Japanese terms, with each step playing an essential role in building and maintaining an efficient working environment:
- Step 1 – Seiri (Sort): This stage focuses on removing unnecessary items from the workspace, keeping only those that are truly useful. The goal is to optimize space and minimize waste.
- Step 2 – Seiton (Set in Order): After sorting, the remaining items are arranged logically to be easy to find, use, and return to their proper place after use. This helps reduce handling time and improves work efficiency.
- Step 3 – Seiso (Shine): Regular cleaning of the workplace is carried out to ensure the space remains clean, while also helping to identify any faults or abnormalities in equipment and machinery early on.
- Step 4 – Seiketsu (Standardize): This step aims to maintain the results achieved in the previous three steps by establishing standardized procedures, issuing specific guidelines, and assigning responsibilities for each area.
- Step 5 – Shitsuke (Sustain): Focuses on building a culture of discipline and responsibility in adhering to 5S, forming good habits as a part of the company culture.
Core principles in the 5S system
To effectively implement the 5S system in factory management and maintain it over the long term, it is essential to fully adhere to the five steps of Seiri – Seiton – Seiso – Seiketsu – Shitsuke. However, this alone is not sufficient. Companies must pay particular attention to the following seven critical factors:
- Principle 1 – Establish standard work: This is the foundation for stabilizing production, which includes three elements: production rhythm based on customer demand (takt time), sequence of operations, and standard inventory levels. When work is standardized, the flow of materials becomes easier to control, processes stabilize, and waste is minimized.
- Principle 2 – Optimize layout for logistics: This principle ensures that the flow of raw materials and finished products is continuous and uninterrupted. Standards for pace, quantity, and specifications in logistics activities contribute to creating a tidy and organized working environment.
- Principle 3 – Perform autonomous maintenance: Employees directly participate in cleaning and inspecting equipment, ensuring the Seiso (Shine) step is followed while also helping to detect any operational abnormalities early. Such proactive maintenance not only extends the life of machinery but also contributes to maintaining a clean and safe working environment.
- Principle 4 – Effective management of defective goods: Implementing a scientific defect control system, with clearly classified and easily visible sorting trays, helps address defective products promptly and prevents them from affecting overall quality. This requires strict adherence to identification, positioning, and quantification rules while enhancing the reliability and efficiency of the production line.
- Principle 5 – Data control: In modern manufacturing, data is no longer a secondary factor but a core tool for decision-making. Proper, timely, and transparent recording, along with the standardization of forms and collection tools, greatly supports the organization, visualization, and retrieval of information.
- Principle 6 – Encourage a culture of continuous improvement: Under the Seiketsu (Standardize) principle, adjusting standards in steps S1, S2, and S3 to align with practical realities is necessary. However, each improvement must be accompanied by updating the standards to ensure consistency and avoid disruptions in operations.
- Principle 7 – Empower the role of team leaders: As direct supervisors on the shop floor, team leaders act as the link between the management system and production reality. They not only monitor the application of the 5S principles but also have the ability to identify emerging issues and implement appropriate solutions.
Companies need to establish and maintain principles for a modern and sustainable production culture
5 specific steps for implementing 5S in the factory
Step 1: Develop a deployment plan and prepare necessary resources
The first step is to create a detailed plan and allocate appropriate resources. The management team should form a 5S task force with representatives from production, maintenance, logistics, and other relevant departments to ensure coordinated efforts across the entire plant.
At the same time, clear implementation goals should be set—these goals must be specific, feasible, and measurable to facilitate progress tracking and assess implementation effectiveness. The deployment plan should outline key timelines, personnel requirements, and individual responsibilities within the team.
Additionally, internal communication plays a crucial role in raising awareness among workers and factory staff. Organizing training sessions, providing visual guides, or displaying banners and bulletin boards in the production area will help effectively spread the 5S spirit.
