TPM: Quality Maintenance (Hinshitsu Hozen) Poster (PDF)

Quality Maintenance is an "advanced" pillar of TPM and aims to assure zero defect conditions. Also known as Hinshitsu Hozen in Japanese, it does this by understanding and controlling the process interactions between the 4Ms – manpower, material, machines and methods that could enable defects to occur. The key is to prevent defects from being produced in the first place, rather than screening them out through inspection systems after they have been produced. Controlling quality through its causes is the essence of Quality Maintenance.

The Quality Maintenance (Hinshitsu Hozen) Poster describes the systematic approach for establishing and maintaining zero-defect conditions to create 100% good products.

The poster is available in professional monochrome versions. The poster comes in a convenient PDF as well as an editable PPTX format, enabling effortless printing on A3/A4-sized paper from standard office copier machines. This versatile resource can be prominently displayed on employee workstations or distributed alongside your training materials.

Furthermore, the poster is an ideal supplement to TPM-related training presentations. It serves as a valuable takeaway, summarizing the core principles of Quality Maintenance and reinforcing the key takeaways from your training.

Step 3: Identify & Analyze 4M Conditions
Step 4: Plan Action to Correct Deficiencies
Step 5: Establish Conditions that Allow Good Products to be Achieved
Step 6: Eliminate Flaws in 4M Conditions and Finalize
Step 7: Consolidate Checking Methods
Step 8: Determine Standard Values for Checks & Revise Standards
