5S – what is it? Principles, steps, and implementation in a company
It might seem that keeping the workplace tidy has little impact on production efficiency – after all, cleaning isn’t directly related to the execution of manufacturing processes. However, the way the workspace is organized can affect the flow of work and the utilization of available resources. This is precisely the premise behind the 5S method, used in Lean Manufacturing. What are its principles, and how can 5S be implemented in a company?
What is the 5S method?
The 5S Method is a way of organizing and maintaining the workplace based on five principles: sorting, organizing, cleaning, standardizing, and self-discipline. The 5S system is one of the tools used in Lean Management and Lean Manufacturing to reduce waste and streamline daily work.
5S has its roots in Japanese production management practices. Its name comes from five words: Seiri, Seiton, Seiso, Seiketsu, and Shitsuke. Each of these words corresponds to a specific area of workplace organization.
However, the goal of 5S is not simply to maintain cleanliness. It is primarily about creating an environment where the necessary equipment is easily accessible, work procedures are clearly defined, and any deviations from the established standard are easy to spot.
What are the 5S principles?
The 5S principles consist of five consecutive stages of organizing and improving the workplace.
| Stage | Japanese name | Meaning | Objective |
|---|---|---|---|
| 1S | Seiri | Sorting | Removing unnecessary elements |
| 2S | Seiton | Systematics | Organizing the necessary equipment |
| 3S | Seiso | Cleaning | Maintaining Ccleanliness and detecting irregularities |
| 4S | Seiketsu | Standardization | Reinforcing the rules for organizing a workstation |
| 5S | Shitsuke | Self-discipline | Maintaining and improving standards |
Seiri – sorting
The first step involves separating the necessary items from the unnecessary ones (e.g., tools, materials, and documentation). Red labels are used to mark items that require a decision on whether to remove, move, or leave them at their current location.
Seiton – systematics
The second stage involves designating fixed, easily accessible locations for the necessary equipment, taking into account how frequently it is used. This is achieved through shelf labels, storage bins, and tool racks, which facilitate visual monitoring of the workstation.
Seiso – cleaning
Cleaning as part of the 5S method also serves a monitoring function. Regular cleaning of workstations and machinery helps detect leaks, damage, and other irregularities. It is also important to eliminate the causes of contamination, not just its effects.
Seiketsu – standardization
The results of the first three stages should be formalized in the form of clear standards. This can be achieved through instructions, photos of model workstations, signage, checklists, and schedules that also define employees’ areas of responsibility.
Shitsuke – self-discipline
The final stage involves reinforcing good habits through training, regular inspections, audits, and leadership engagement. In addition to ensuring employee discipline, it is crucial to foster a sense of responsibility for adhering to standards.
How does 5S relate to Lean Manufacturing and Kaizen?
5S is one of the tools of Lean Manufacturing, an approach to production management based on reducing waste and creating value for the customer. It helps eliminate unnecessary movement, reduce the time spent searching for equipment, and minimize organizational errors.
Kaizen, on the other hand, focuses on continuous process improvement, including through an employee suggestion system that allows employees to propose improvements. A well-organized workstation and clear standards in line with 5S make it easier to identify problems and suggest changes.
The benefits of implementing 5S in manufacturing are confirmed by studies conducted at manufacturing companies:
- Reducing production cycle times – a study published in 2022 in *Cleaner Engineering and Technology* showed that at a plastic film packaging plant, after implementing 5S, the blow-molding cycle time was reduced by 8% and the printing cycle time by 18%.
- Reducing the time spent searching for tools – a study published in 2015 in the *International Journal of Engineering Sciences & Research Technology* reported that the average daily time an employee spent searching for tools was reduced from 40 to 5 minutes after workstations were reorganized according to the 5S principles.
Where can the 5S method be applied?
Although one of the most common applications of the 5S method is in manufacturing, its principles can also be applied in warehouses, offices, and digital environments.
On the production floor, 5S helps organize tools, measuring instruments, components, and technical documentation. Examples include designating storage locations for tools and using labels that allow for quick identification of missing items.
In a warehouse, the 5S method helps organize storage, order picking, and packing areas. Marking locations, organizing auxiliary materials, and designating spaces for transport equipment reduce the time spent searching for equipment. The 5S principles can also help keep traffic routes clear.
In the office, the 5S principles are applied to the organization of documents, materials, and workstation equipment. A similar approach can be used in the digital space by implementing a consistent file-naming convention, a well-organized folder structure, and rules for archiving documents.
How to implement 5S in your company, step by step?
Successful implementation of 5S requires employee engagement, the assignment of responsibilities, and a plan for maintaining standards. How can 5S be implemented so that the changes yield lasting results?
How does noSilo help maintain 5S standards?
Implementing the 5S method does not require specialized software. However, digital tools can make it easier to manage standards, especially in companies with many workstations or distributed teams.
The noSilo platform supports work organization in several areas that are essential for maintaining 5S:
- Digital guidelines and work standards – make it easier to share up-to-date workplace policies and reduce the use of outdated documentation.
- Checklists – they help organize repetitive tasks and confirm that they have been completed in accordance with the established scope.
- Training and onboarding – help new employees become familiar with established procedures and standards.
- Kaizen suggestions – allow you to submit ideas for improving work organization and engage the team in continuous improvement.
- Machine autonomous maintenance checklists – support the implementation of scheduled inspection tasks and the reporting of equipment malfunctions.
The 5S method helps reduce losses resulting from poor workstation organization and lays the groundwork for further process improvement. For manufacturing companies, this means increased efficiency through shorter operation times, reduced organizational downtime, and better utilization of working time.
FAQ
Yes. The 5S standard should be updated as processes, equipment, or work organization change. Modifications should take into account employee observations and audit results, and then be documented and communicated to the entire team.
An audit involves evaluating a workstation based on the five 5S principles. It uses checklists, scoring, observations, and interviews with employees. Any nonconformities identified require the development of corrective actions and monitoring of their implementation.
Clear standards, a division of responsibilities, and regular audits are essential. The 5S principles should be incorporated into training for new employees, and reported issues should be used to improve workstation organization.
It is important to monitor audit results, tool search times, the number of nonconformities, and workstation setup times. To assess the actual impact of 5S on work organization, these metrics should be compared with pre-implementation results.
