The 5S approach originated within the Toyota Production System in Japan as a lean manufacturing tool designed to reduce waste, improve efficiency, and enhance productivity. This organizational method complements other lean practices like kaizen and kanban, aiming to create a clean, orderly workspace that supports streamlined workflows and valuable business outcomes.

The 5S lean manufacturing approach stands for Sort (Seiri), Set in Order (Seiton), Shine (Seiso), Standardize (Seiketsu), and Sustain (Shitsuke), and serves as a foundational platform within lean manufacturing that helps establish a clean, safe, and well-structured work environment. This stable framework supports the effective implementation of other continuous improvement methodologies such as Total Productive Maintenance (TPM), cellular manufacturing, and Kaizen activities, enabling optimized productivity and reduced waste. The 5S methodology extends beyond physical organization to foster a mindset of ongoing workplace efficiency through visual cues and routine tasks.

What is 5S in Manufacturing?

The 5S approach began as part of the Toyota Production System. This Japanese system of organization is meant to provide valuable business outcomes alongside other lean manufacturing practices, such as kaizen, kanban, jidoka, heijunka and poka-yoke. Lean manufacturing organizational practices originated in Japan in the early to mid-20th century and were adopted by American businesses toward the late 20th century. 

While the lean manufacturing 5S philosophy can sound a bit abstract, it’s actually a very practical, hands-on methodology, with success requiring participation from all workers. The philosophy is centered on the premise that when a workplace is properly organized, it functions better. This could include arranging the physical environment of a workspace in a way that’s more conducive to workflow, with tools and materials placed in locations based on who needs them and how frequently they’re needed.

What Does 5S in Manufacturing Stand For?

According to the methodology, the path to optimal workplace organization lies in the five steps that should be done in a particular order. 5S, also known as Five S, is an acronym for five Japanese words:

• Seiri 整理 (organize)
• Seiton 整頓 (orderliness)
• Seiso 清楚 (cleanliness)
• Seiketsu 清潔 (standardize)
• Shitsuke しつけ (discipline)

In English, the 5S terms have been adapted to:

• Sort
• Set in Order/Straighten
• Shine
• Standardize
• Sustain

Let’s look at each step of 5S in manufacturing in more detail.

1. Sort (Seiri 整理)

The “sort” phase of the 5S in manufacturing involves sorting through all tools, furniture, equipment, materials, resources, etc. in the work area to determine what is needed and what can be eliminated. Some common questions are asked during this phase, such as:

• What is this item’s purpose?
• How is it used?
• How frequently is it used?
• Who uses it?
• Is it really needed?

The involvement of staff is required to answer some of these questions in this step of the 5S methodology. Items deemed unnecessary to the workspace are removed.

In this phase, the concept of “red tagging” is used to identify and remove unnecessary items from the workspace. Items that are not essential to daily operations are tagged with a red label and moved to a designated holding area for further evaluation. From there, each item is assessed for disposal, recycling, or reassignment, ensuring only useful materials remain in the work environment.

2. Set in Order/Straighten (Seiton 整頓)

With the clutter removed, the next step of the 5S methodology can proceed: organizing the remaining items. Common item grouping systems include:

• Who uses the item
• Where the item is used
• When the item is used
• Item type

With items appropriately grouped, they’re then arranged neatly in a way that is most logical to the identified workflow.

Here, the focus is on organizing tools and materials so that each item has a designated spot—captured by the maxim, “a place for everything and everything in its place.” This principle promotes efficiency by ensuring that workers can quickly find what they need and return it when finished. Techniques such as shadow boards and labeled storage help enforce location discipline, reducing search time and maintaining an orderly workspace.

3. Shine (Seiso 清楚)

In the Shine phase of 5S in manufacturing, the workplace is thoroughly cleaned. The goal is to keep the workspace in order and identify any equipment breakdown that would slow down progress. This includes basic cleaning like dusting, sweeping, tidying, and mopping, as well as performing regular maintenance on equipment and machinery. And it isn’t just the janitorial staff expected to keep the area clean. Employees are encouraged to maintain their workspace, giving them a sense of ownership meant to further their investment in their role.

In Seiso, cleaning is viewed not just as housekeeping but as a form of inspection. Routine cleanup allows workers to spot early signs of equipment wear, leaks, or potential health hazards that might otherwise go unnoticed. By integrating cleanliness with inspection, organizations can maintain safer, more reliable operations while fostering accountability in the workplace.

4. Standardize (Seiketsu 清潔)

The standardization step is designed to prevent a company from slipping back into old ways after the progress of the first three steps. Organizing and cleaning aren’t an every-now-and-then practice in a 5S workplace. By standardizing the principles, regular tasks are assigned, schedules are made, and instructions are given to ensure these activities become habit or standard operating procedures. Visual cues, such as posters and labels, help to ingrain practices into the work culture. 

5. Sustain (Shitsuke しつけ)

To sustain the 5S lean methodology, consistent participation from all workers is essential. This is often achieved through tools like job cycle charts, visual cues, checklists, and scheduled “five-minute” 5S periods. Managers and employees across departments should be involved, making sustaining 5S a team effort and a key part of new employee training. With everyone engaged, 5S becomes an ongoing, long-term commitment.

To ensure that 5S practices become lasting habits, Shitsuke focuses on maintaining discipline and reinforcing continuous improvement through structured tools and routines.

Key tools for sustaining improvement include:

• Job Cycle Charts – Visualize daily or weekly responsibilities, helping employees integrate 5S tasks into regular workflows and maintain accountability.
• Visual Cues – Signs, labels, and color coding that serve as constant reminders of proper organization, placement, and cleaning standards.
• Scheduled “Five-Minute” 5S Periods – Brief, dedicated intervals at the start or end of shifts to reinforce order, cleanliness, and consistency.
• Checklists – Step-by-step guides that ensure all 5S activities are performed regularly and that standards remain consistent across teams and shifts.

In Shitsuke, this lasting success is promoted through continuous commitment, regular audits or reviews, and a culture of employee ownership over their work areas. By encouraging everyone to take responsibility for organization and cleanliness, companies can ensure that 5S becomes a lasting part of daily operations rather than a one-time initiative.

The Sixth S in Manufacturing: Safety

Along with the standard 5S in manufacturing, some companies add safety to their approach. While the above principles are designed to promote safety and regulatory compliance through clean, organized, well-functioning workspaces, there is still more that can be done to reduce risk for employees. This can include making workstations more ergonomic, clearly marking the path for forklifts, and the better labeling of hazardous chemicals and machines.

Benefits of 5S in Lean Manufacturing

The 5S lean manufacturing methodology has precise goals that lead to measurable benefits, including reducing the seven types of waste identified in the Toyota Production System—such as unnecessary transport, inventory, motion, waiting, overproduction, over processing, and defects—while also improving safety and overall operational efficiency. Common benefits for companies that adopt 5S include waste reduction, enhanced productivity, and a safer, more organized workplace.

• Reduced waste
• Increased employee morale and engagement
• Foundation for continuous improvement
• Enhanced Quality: A well-maintained and standardized environment makes it easier to spot potential defects or issues, leading to better quality control
• Cost Savings: By optimizing resources, reducing waste, and improving equipment longevity through regular cleaning and inspection, companies can lower operational costs

Getting Started with 5S in Lean Manufacturing

Employee buy-in is critical when adopting 5S. When a company or department decides to implement 5S strategies, everyone must be involved from the top to the bottom, with no one left out. While some employees may take on a larger role in carrying out the principles, participation is needed from all to ensure there are no gaps in the process.

Begin by talking with employees. Educate them on the 5S principles and the benefits for the company and for them personally. Provide examples of how to implement 5S in their workstation and what success looks like. Allow employees to weigh in on your 5S vision, and work with them to create a structure that is doable and valuable to their workflow.

Training can be done through books, instructional videos or hands-on exercises. Discuss ways that visual communication tools, such as floor markers, signs, posters and labels can be helpful in the workspace. As employees become more educated about the 5S principles, some will likely emerge as voluntary leaders in organizing teams and processes and overseeing implementation.

Implementing the right tools, such as next generation ERP technology, is also key to starting and sustaining a successful 5S structure. ERP software is a vital ally to lean manufacturing principles, promoting further efficiency, productivity, organization and communication within the workplace. QAD’s solutions transform companies in these areas, enabling them to work in a more streamlined and profitable manner.
