Factory management is a complex field that requires adherence to rules and regulations One overarching goal: maintain quality and quantity, meet deadlines and comply with regulations, always striving to achieve zero defects. Two key points: the first unit must be produced perfectly, with minimal issues resulting from thorough inspections. Abnormalities in the process must be taken seriously; resolve the issues before remanufacturing. The three “no” policies: Do not accept defective products, do not produce defective products, and do not overlook defective products. The four key practices: Follow the requirements of the operation instructions to understand the essentials of one’s own role; refer to specifications and standards; check before starting work (first-piece inspection); verify after completion. The five core concepts: Meet customer requirements without compromising on quality; quality is not ensured through inspection alone, but through design, manufacturing, and consistent practices; proactive self-inspection is more effective than numerous passive inspections; get it right the first time, as any repairs or rework can affect quality; “more or less,” “roughly,” or “seemingly” are the biggest enemies of quality. The six principles of not overlooking anything: If the cause cannot be 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 measures are not incorporated, do not move on. The seven types of waste: waiting, handling, transportation, overproduction, inventory, defective products, and unnecessary processing. The eight steps for solving problems: Identify the problem, break down the problem, set goals, determine the root cause, develop countermeasures, implement those countermeasures, evaluate the results and process, and consolidate the achievements. The nine steps for dealing with quality issues: Detect the problem, select the relevant items using quality-SPC methods, investigate the cause, analyze data, propose solutions, choose the appropriate targets, draft action plans, compare the results, and standardize the processes. The 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 other methods? (Methods) Simplify the work. How much—To what extent has it been completed, what is the cost? (Extent, Cost) [4M1E] Man—People; Machine—Machines; Material—Materials; Method—Methods; Environment—Environment. VIA techniques, Value Analysis, Value Engineering, Industrial Engineering techniques, Quality Control techniques. Quality control circle activities: A small group of 5–10 people 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: Inspect and verify data; control to prevent variations; histograms to show distributions; Pareto to identify key issues; scatter plots to find correlations; stratification to detect differences; characteristic analysis to pinpoint root causes. The 8D method involves forming a team, describing the problem, taking immediate action, expanding efforts across different areas, containing defects, analyzing the current situation, identifying initial causes and temporary solutions, finding root causes and permanent solutions, confirming the effectiveness of these measures, expanding actions further, and implementing preventive measures. Standardization, documentation, and consolidation are also important. [The 3 Nos and 5 Principles] 3 Nos: Go to the site, see the actual items, and understand 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 components being produced). B. Identify the causes (paths of occurrence, tests to reproduce the problem, 5 WHY analysis). C. Determine appropriate countermeasures (content of actions, predicted effects). D. Confirm the effectiveness of the countermeasures. E. Provide feedback at the source level, ensuring that these actions are integrated into system and organizational standards. Mnemonic for implementing 5S management: Sorting: Separate necessary from unnecessary items, keeping only what’s needed. Organizing: Arrange items in a logical way 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 detecting anomalies using control charts: One point outside the range, 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 habit! 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 keep the business going. 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. No being late, no leaving one’s post, abiding by discipline and having 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 proactivity. No arguing, no noise; just nod and smile when we meet. You show respect for me, I show respect for 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!
