✅ Garments Quality Section GEMBA Tools (Most Practical List)

1. 5S (Sort–Set–Shine–Standardize–Sustain)

Quality floor clean, organized, defect-free flow রাখার জন্য সবচেয়ে বেসিক টুল।

• Needle box, trims tray, size-set organized

• Sewing line workstation clean

• Measurement tools fixed position

2. Visual Management

গার্মেন্ট QC / Line Chief–কে live status দেখাতে:

• Defect tag color system

• Output/Reject board

• Traffic light system (Red–Yellow–Green)

• Size-set display board

3. Standard Work

একই operation everywhere same way.

• Operation bulletin (OB)

• Machine layout map

• QC checkpoint chart

• Standard measurement sheet

4. Gemba Walk Checklist

Floor এ গিয়ে real-time problem detection:

• Stitch quality

• SPI accuracy

• Thread tension

• Seam puckering

• Needle condition

• Quality audit points

5. Root Cause Analysis (RCA)

Quality defect হলে আসল কারণ খুঁজে বের করা।
Tools:

• 5 Why

• Fishbone Diagram (Man, Machine, Method, Material, Environment)

Garments defect উদাহরণ:

• Broken seam → Needle blunt

• Uneven stitch → Feed-dog worn

• Shade variation → Incorrect fabric lot mixing

6. Poka-Yoke (Error Proofing)

Defect ঘটার আগেই ব্লক করার টুল।
Garments examples:

• Wrong panel attach prevent by color-coded matching

• Shade mismatch block by lot separation system

• Needle policy (broken needle record)

• Guide attachment on machines

7. Kaizen (Continuous Improvement)

Factory floor-এ continuous improvement:

• Excess motion reduce

• Operation balancing

• Seam allowance marking improvement

• Quality rework table optimization

8. AQL Inspection Method

Final quality inspection.

• AQL chart

• Sample selection

• Major / Minor defect counting

9. PDCA Cycle

Plan–Do–Check–Act → Quality improvement loop.
Used for:

• Reject reduction project

• Overlocking seam puckering problem fix

• Quality training improvement

10. Andon System

Real-time problem notification.

• QC finds defect → Press Andon → Line supervisor arrives

• Stops continuous defect generation

11. Takt Time & Line Balancing

Indirectly quality improves because operators are not overloaded.

• Bottleneck reduce

• Less hurried work → fewer defects

12. 7 QC Tools

Garments quality control-এ must use:

• Check sheet

• Control chart

• Pareto chart

• Histogram

• Scatter diagram

• Flow chart

• Cause & effect (Fishbone)
