5S management is not only a management method but also a management philosophy. It does not require any complex principles or technologies; rather, it is a practical management approach that requires minimal investment yet yields significant results. It is particularly well-suited for on-site management in laboratory testing environments and is essential for improving such management. So, how can laboratories effectively implement 5S management on-site? Mastering the right implementation techniques is key. Below, we will discuss the implementation techniques for 5S management in laboratories:
I. Refining the Daily Organizational Model for 5S Management
To successfully implement 5S management, careful planning and thorough preparation are required in advance, along with the establishment of a well-structured organizational model for implementation. 5S management activities are inherently demanding, and at the outset, employees generally lack a sense of buy-in. Therefore, a dedicated department must be established to drive the initiative from the very beginning. This department can assume responsibilities such as: setting 5S policies and objectives; formulating implementation plans and work schedules for 5S activities and overseeing their execution; and developing 5S management documentation in accordance with the work plans. Each operational department within the laboratory should also establish an implementation team. Based on the overall implementation plan and schedule, these teams should propose departmental implementation plans and assign specific responsibilities to designated personnel. Once 5S becomes a habit for every employee, the driving role of the dedicated department will naturally diminish, at which point responsibility for driving the initiative can be transferred to the operational departments.
II. Implementing the 5S Management Initiative According to the Correct Steps
Implementing the initiative according to the correct steps is a critical aspect. If the steps are incorrect, it may lead to significant resistance, result in inefficient efforts, or even cause the initiative to be abandoned midway. The correct steps are generally as follows:
1. 5S Management—Sorting (Seiri)
Each testing station staff member should conduct a comprehensive inspection of their own testing work area. They should categorize items in the testing area (including testing reagents, reference standards, glassware, instruments, equipment, tooling, and fixtures) into two categories: necessary and unnecessary, and remove the latter from the testing area or dispose of them. When distinguishing between necessary and unnecessary items, criteria for determination must be established. For example, it may be stipulated that “essential items” refer to chemicals, tools, and other items that must be used daily or weekly. If an item is used only once a month or less, it should be placed in a temporary storage area rather than left in the testing area. Therefore, a temporary storage area must be designated before sorting begins. The criteria for determining whether to keep or discard items during the sorting phase are their utility and frequency of use in the testing area. Rules should be established based on each laboratory’s specific circumstances; for example, items used monthly should remain on-site, those used once a month or less should be moved to the temporary storage area, and items not used by the laboratory should be discarded without hesitation. If an item is of no use whatsoever to the laboratory, it should be discarded without hesitation—regardless of who purchased it or how much it cost.
2. 5S Management—Set in Order (Seiton)
After the “Sort” phase comes “Set in Order.” Arrange the necessary items identified during the “Sort” phase according to the principle of convenience for testing, so that the time spent searching for them is reduced to zero. For example, based on the sample testing workflow, plan the placement of instruments and equipment rationally: frequently used items should be placed closer (such as within easy reach while working), while items used less frequently can be placed farther away (such as grouped in a specific area of the room). Where possible, create a floor plan for each testing area, clearly marking the location of each item. In addition to organizing the testing sites, the supply warehouse must also be organized. Items should be arranged in designated zones within the warehouse based on their frequency of use, with clear labeling to ensure everything is immediately visible, allowing testing personnel to locate the necessary items promptly.
For items identified as unnecessary during the sorting phase, establish procedures for waste disposal. In keeping with the principles of thrift and frugality, these “unnecessary” items should be recycled to turn waste into resources; for items that need to be scrapped, follow the proper scrapping procedures to recover their “residual value.” When disposing of waste, implement environmental protection measures to prevent pollution. In fact, organizing is also a science dedicated to improving efficiency. It is essential to analyze and determine how to establish a system that ensures items can be retrieved immediately when needed and returned to their proper places promptly after use—one in which missing or misplaced items can be spotted at a glance. Furthermore, everyone must understand this system and adhere to it.
3. 5S Management—Cleaning (Seiso)
Keep the workplace clean and tidy. Each inspector is responsible for cleaning their own personal items, such as equipment and tools, and should not rely on others to do so. Cleaning of equipment should be integrated with equipment inspections and maintenance. Cleaning is also a means of improvement. If oil or water leaks are discovered while cleaning the floor, or if equipment malfunctions, the cause must be identified and corrective measures taken.
4. 5S Management — Cleanliness (Seiketsu)
After sorting, straightening, and sweeping, diligent maintenance is required to keep the workplace in perfect and optimal condition. Cleanliness involves the consistent and in-depth implementation of the first three activities, standardizing and institutionalizing the practices established through sorting, straightening, and sweeping. It preserves the results of the preceding 3S steps, thereby eliminating the root causes of safety incidents. This creates a positive work environment where employees can work with satisfaction. The laboratory should organize relevant personnel to compile best practices from the 3S into 5S operational guidelines, thereby standardizing 5S management.
5. 5S Management—Discipline (Shitsuke)
Striving to improve staff discipline and fostering a habit and culture of strictly adhering to rules and regulations is the core of the “5S” initiative. Without improvements in staff quality, various activities cannot be carried out smoothly, and even if implemented, they cannot be sustained. Therefore, when implementing 5S management, the focus must always be on enhancing staff quality. Everyone should conduct regular supervision and inspections of 5S management. Through continuous supervision and inspection, the laboratory’s “5S” implementation guidelines will ultimately become individual work habits for employees. Starting with meeting basic requirements, this will gradually lead to a positive improvement in staff quality. During the implementation of 5S, a 5S inspection team can be established to conduct inspections and provide guidance at different stages, ensuring that the 5S management initiative meets requirements and is completed on schedule. The implementation of 5S management not only standardizes the placement of items but also standardizes our daily behavioral habits.
Cultivating a good habit is a long-term process. Managers serve as the direct supervisors of these habits and must conduct frequent inspections without the slightest complacency; otherwise, all previous efforts will be in vain. To ensure effectiveness, the laboratory can select departments with relatively strong foundational conditions to pilot the 5S initiative as model units. After gaining experience from these pilot programs, the initiative can be rolled out throughout the laboratory, gradually standardizing on-site testing management, enhancing staff professionalism, and continuously improving the laboratory’s on-site testing management standards.
III. Continuous Optimization and Improvement of 5S Management
Laboratories must strengthen awareness of 5S management to encourage staff to develop good behavioral habits and promote the gradual improvement of their professional competence. When implementing 5S management in the laboratory testing environment, the principles of the PDCA cycle must be adhered to. Through planning, implementation, checking, and improvement, issues arising in 5S management should be continuously identified, and corrective measures proposed to address them, thereby ensuring the healthy development of 5S management. Only through continuous improvement can 5S management be sustained over the long term.
