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; I have organized them thoroughly, and they are very useful, so I’d like to share them with everyone. 【One overall goal】 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】 1. Conduct thorough first-piece inspections to avoid having to fix errors later. 2. Pay close attention during the manufacturing process: detect abnormalities, stop production, take corrective actions, resolve the issue, and then resume production. 【Three No’s Policy】 1. Do not accept defective products. 2. Do not produce defective products. 3. Do not overlook defective products. 【Four Practices】 1. Follow the requirements of the operation instructions to understand the key points of one’s own role. 2. Refer to specifications and standards. 3. Check before proceeding (first-piece inspection). 4. Verify after completion. 【Five Mindsets】 1. Meet customer requirements; quality cannot be compromised. 2. Quality is not achieved through inspection alone, but through manufacturing and design practices. 3. Proactive self-inspection is more effective than numerous passive inspections. 4. Ensure tasks are done correctly from the start to avoid affecting quality through repeated repairs and rework. 5. “More or less,” “roughly,” and “apparently” are the biggest enemies of quality. 【Six SIGMA】 If the cause is not identified—do not let it go; if responsibilities are unclear—do not let it go; if corrective actions are not implemented—do not let it go; if corrective actions are not verified—do not let it go; if effective measures are not adopted—do not let it go. 【Seven Wastes】 Waiting, transportation, movement, overproduction, inventory, defective products, and unnecessary processing. 【Eight Principles】 Customer focus, leadership, full employee participation, process-based approach, systematic management, continuous improvement, decision-making based on facts, and mutually beneficial relationships with suppliers. 【Nine Steps】 1. Identify problems and select projects—quality-SPC. 2. Trace the causes. 3. Analyze data. 4. Propose solutions. 5. Choose the target area. 6. Draft action plans. 7. Compare results. 9. Standardize. 【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—Equipment; Material—Resources; Method—Approaches; Environment—Conditions. [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 the VIQ technique, apply the PDCA management cycle, and promote autonomous management with full participation from all members. 【Mnemonic for the 7 QC Tools】 Inspection, data collection, control, variation prevention, histograms to show distribution, Pareto to identify key issues, scatter plots to find correlations, grouping to detect differences, characteristic analysis to pinpoint root causes. 【8D Method】 Form a team, describe the problem, take immediate action, conduct a thorough analysis of the current situation, identify initial causes and temporary solutions, determine root causes and permanent fixes, verify the effectiveness of the solutions, implement foolproof measures, standardize processes, and celebrate achievements. 【The 3 As and 5 Principles】 3 As: The site, the actual items, the current situation. 5 Principles: A. Understand what happened (phenomena, complaints, frequency of occurrences); grasp the facts (results of component inspections, cause analysis, quality status of the 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. Verify the effectiveness of the solutions (confirm their actual impact). E. Take actions at the source (implement changes in systems and organizational standards). 【Mnemonic for Implementing 5S Management】 Sorting: Separate necessary from unnecessary items; keep what’s needed and get rid of the rest. Straightening: Arrange items in an orderly manner for easy access. Cleaning: Keep the environment tidy 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 speak face to face; if you don’t come, I won’t leave. Machine maintenance: axes should be visible, grooves should reach the bottom, the machine should show its true color, and warnings must be clear. Listen, look, touch, and restore. Safety: Safety first, prevention foremost. 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. For the conversion task, the remaining labels need to be cleaned up, unused materials should be returned promptly, old products need to be cleared away as soon as possible, and used documents must be collected. Quality: 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: Without a production plan, management is overwhelmed. The plan is unreasonable, making control difficult. Poor control leads to 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 over 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 to the left, look to the 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 proactive efforts. 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 in a good mood, let’s work together to achieve great results! 【Mnemonic for number rounding rules】 Drop 6 and keep 4; always round up when encountering 5. If there’s a digit after 5, round up accordingly. When 5 is followed by zero, pay attention: 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. - End -
