Quality management is a complex and systematic endeavor that involves a wide range of knowledge. How can this knowledge be applied to actual work and replicated? Some seniors have compiled these quality management mnemonics, which are very useful; I’d like to share them with everyone. 【One overall goal】To produce products that meet the requirements of customers and regulations on schedule and in full quantity, continuously striving to achieve zero defects. 【Two Key Points】 Thorough inspection of the first piece is essential to avoid having to fix errors later. Attention must be paid during the manufacturing process (to detect any abnormalities): stop production, take action, resolve the issue, and then resume production. 【Three No’s Policy】 Do not accept defective products, do not produce defective products, and do not overlook defective products. 【Four Practices】 Follow the requirements of the operation instructions and understand the key points of one’s own role; refer to specifications and standards; check before starting work (first-piece inspection); confirm after completing the work. 【Five Concepts】 Meet customer requirements – quality cannot be compromised. Quality is not achieved through inspection alone, but through manufacturing and design practices; proactive self-inspection is more effective than numerous passive inspections. Do not let repeated repairs and rework affect quality when something can be done right from the start. “More or less,” “approximately,” and “seemingly” are the biggest enemies of quality. 【Six Sigma】 If the cause is not identified, do not move on; if responsibilities are unclear, do not move on; if corrective actions are not implemented, do not move on; if corrective actions are not verified, do not move on; if effective actions are not incorporated, do not move on. 【Seven Wastes】 1. Waiting 2. Transportation 3. Movement 4. Overproduction 5. Inventory 6. Defective products 7. Waste in processing. 【Eight Principles】 Customer focus, leadership, full employee participation, process-oriented approach, systematic management methods, continuous improvement, decision-making based on facts, and mutually beneficial relationships with suppliers. 【Nine Steps】 Identify problems, select projects related to quality and SPC, investigate the causes, analyze data, propose solutions, choose targets, draft action plans, compare results, and standardize processes. 【5W2H Method】 What – What is the problem? (Major issues) Why—Why do this? (Goal) Define the goal and eliminate unnecessary steps. Where—Where/To what extent has it been completed? (Location) When—is the best time to start/finish? (Time) Selection—Who will carry out the task and who is responsible? (People) How—How to complete it; are there any alternative methods? (Methods) Simplify the work. How much—To what degree has it been completed, what is the cost? (Degree, Cost) [4M1E] Man—People; Machine—Machines; Material—Materials; Method—Methods; Environment—Environment. [VIA techniques] Value Analysis technique; Value Engineering technique; Industrial Engineering technique; Quality Control technique. [Quality control circles] A small group of 5–10 colleagues from the same workplace come together to address problems at their workstations. They use VIA techniques, apply the PDCA management cycle, and promote autonomous management with full participation from all members. 【Mnemonic for the 7 QC Tools】 Check and verify data; control to prevent variations. Histograms reveal distribution patterns; Pareto analysis identifies key issues. Scatter plots help find correlations; stratification reveals differences. Characteristic analysis uncovers root causes. 【8D Method】 Form a team, describe the problem, take immediate action, expand efforts across all levels, contain defects, analyze the current situation, identify initial causes and temporary solutions, determine root causes and permanent fixes, confirm the effectiveness of the solutions, implement preventive measures, standardize processes, and celebrate achievements. 【The 3 As and 5 Principles】 The 3 As: the workplace, the actual items, and the current situation. The 5 Principles: A) Understand what happened (phenomena, complaints, frequency of occurrences); ascertain the facts (results of component inspections, cause analysis, quality status of components being produced). B) Identify the causes (pathways of occurrence, tests to reproduce the problem, 5 WHY analysis). C) Develop appropriate solutions (content of the solutions, predicted effects). D) Confirm the effectiveness of the solutions (verify their actual impact). E) Implement changes at the source (integrate these changes into system and organizational standards). 【Mnemonic for Implementing 5S Management】 Sorting: separate necessary from unnecessary items, keep only what’s needed. Organizing: arrange items logically for easy access. Cleaning: maintain a clean environment so that everything is readily available. Standardizing: establish rules and ensure they are followed consistently. Sustaining: adhere to the rules and develop good habits. 【Mnemonic for Identifying Anomalies in Control Charts】 One point outside the limits, nine points on the same side ； Six rises and six falls, 14 alternating ； 2/3 outside B, 4/5 outside C ； 15 inside C, 8 outside C. 【Mnemonic for production site management】 During shift handover, hold hands and communicate face to face; if you don’t come, I won’t leave. The machine’s maintenance shafts should be exposed to light, the grooves should be visible to the bottom, the machine should show its true color, and the warnings must be clear. Listen, look, touch, and restore. Safety first, prevention is key. Safety is no trivial matter; life is more important than anything else. Luck is the beginning of danger. Go to work happily, and return home safely. The remaining labels from the conversion process need to be cleaned up; unused materials should be returned promptly, old products should be cleared away as soon as possible, and used documents need to be collected. Quality is created, not inspected; it is designed, and *developed through habits! Production without quality is equivalent to crime. Product quality must be kept in mind ； Identify the standards and find the right direction ； The first sample must be complete; don’t forget the guidelines ； Pay attention to the method; handle it gently ； Pay attention to self-inspection and use the right packaging ； Write the labels correctly and store them promptly. Production planning is lacking, leaving management overwhelmed. The plan is unreasonable, making control difficult. Lack of effective control results in unsatisfactory delivery times. If delivery times are not on schedule, it’s difficult to sustain business operations. Morale, one, two, three; three, two, one – there is morale at the production site. You help me, I help you; we meet and smile at each other. United in love, in a good mood; there are no distances between people from all corners of the world. One, two, three, four, five, six, seven – moving in unison to be number one. Be punctual, do not leave your post, abide by discipline, and have ideals. Wear the brand logo, put on the company uniform, stand tall with confidence and energy. Look left, look right – keep it organized and tidy. Raise your legs, lift your feet – keep the ground clean of trash. Checking samples and documents is crucial to ensuring quality. Focus on output and efficiency; increase income through proactivity. No arguing, no noise; just a nod and a smile when we meet. You respect me, I respect you; people from all over the world are neighbors. United in friendship and good spirits, let’s work together to achieve great results! 【Mnemonic for number rounding rules】 Round down at 4, round up at 6; for 5, follow the digit after it. If there’s a digit after 5, round up; if it’s zero, check carefully: if the digit before 5 is odd, round up; if it’s even, do not round up. No rounding is done during calculation; rounding should be performed only after the calculation is complete.
