Introducing Our World-Class Manufacturing Sites

At JOHNAN SIAM, we are committed to maintaining exceptional quality, a safe environment, and optimal productivity across all our production sites. To achieve this, we diligently implement 5S activities and other continuous workplace improvement initiatives daily. Below, we introduce some of these key activities.

Our Comprehensive 5S Activities

WHAT IS “5S”?

“5S” is a systematic methodology, named after five Japanese words starting with ‘S’: Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). These principles are fundamental to enhancing and maintaining an organized, efficient, and safe workplace environment within the manufacturing industry.

The Five Pillars of 5S at JOHNAN SIAM:

整理/Seiri (Sort)

Distinguishing between essential and non-essential items, and removing what is unnecessary.

整頓/Seiton (Set in Order)

Establishing a designated and efficient place for every item, ensuring quick retrieval and return.

清掃/Seisou (Shine)

Maintaining a consistently clean workplace, which aids in easily identifying abnormalities and potential issues.

清潔/Seiketsu (Standardize)

Creating a standardized system to ensure that the first three ‘S’s (Seiri, Seiton, and Seiso) are consistently applied and maintained.

躾/Shitsuke (Sustain)

Cultivating the discipline and habit of consistently following established procedures and maintaining the improved workplace standards.

Our 5S activities are rigorously implemented across our entire work site to significantly enhance overall productivity. This is achieved by improving quality and work efficiency, minimizing defective losses, and consistently ensuring a safe and organized work environment.

Below are some illustrative examples of the 5S activities we have successfully implemented.

EXAMPLES OF 5S ACTIVITIES: Enhancing Efficiency Through Practice

Case Study: Optimized Parts Management

(Before change)

(After change)

Initial Problem:

  1. Parts were mixed indiscriminately in storage boxes, leading to difficulties in retrieval and significant time loss.
  2. The absence of First-In, First-Out (FIFO) management created a risk of material deterioration due to prolonged storage.
  3. Improper storage methods directly compromised the quality of the parts.

Improved Solutions

  1. We established designated storage areas and implemented visual management systems for all inventory items, ensuring clear oversight.

  2. To enhance usability and access, different types of equipment are now managed and stored separately.

  3. By arranging parts on dedicated carts, we have successfully implemented a First-In, First-Out (FIFO) system.

  4. Organizing parts by control part number now allows for rapid retrieval of needed components.

Case Study: Streamlining Production Supply Management

Initial Problem

  1. It was challenging to identify missing production supplies, leading to potential delays.
  2. Disorganized storage resulted in significant time consumption for preparing items for warehouse delivery.

Improved Solutions

  1. We established designated storage areas and implemented visual management for all inventory items, enabling quick identification of supply levels.

  2. To improve efficiency, various types of equipment are now managed and stored separately.

Case Study: Optimizing Workspace & Tool Management

Initial Problem:

  1. Unnecessary items cluttered the work areas.
  2. There was no specified or standardized placement for tools, equipment, and other resources.

Improved Solutions:

  1. We systematically removed unwanted materials, creating a safer and more efficient work environment.

  2. Dedicated storage areas have been established to effectively monitor the usage of tools and equipment.

Case Study: Stationery & Supply Condition Management

Initial Problem:

  1. Stationery and supplies were often left in a damaged condition.
  2. Even unused items were improperly stored or left out.

Improved Solutions:

  1. All equipment is now regularly checked for condition, and any damaged items are promptly discarded.

  2. By implementing fixed location management and promoting shared resource utilization, we have significantly reduced equipment order frequency.

Case Study: Material Warehouse Organization

Initial Problem:

  1. Materials were disorganized, leading to significant time loss in locating specific items.
  2. Missing materials were not readily apparent, impacting production planning.

Improved Solutions:

  1. We have thoroughly organized material placement and implemented clear identification systems for all inventory.

  2. To effectively track and prevent material shortages, our management system now operates on a Max-Min stock level basis.
