• 确定数据来源：明确从生产环节的各工序质检记录、成品抽检报告、客户反馈记录以及供应商原材料检验报告等获取质量数据。
• 制定收集标准：规定数据的记录格式、精度要求，例如缺陷数量精确到个位，质量指标数值保留两位小数等，确保数据的一致性和准确性。
• 责任分配：指定专人负责各数据源的数据收集，如生产线质检人员负责工序质检数据，客服人员收集客户反馈数据，采购部门对接供应商检验数据

Determine data sources: Clearly obtain quality data from various process quality inspection records, finished product sampling reports, customer feedback records, and supplier raw material inspection reports in the production process.
Establish collection standards: specify the recording format and accuracy requirements for data, such as the number of defects to be accurate to one decimal place and the retention of quality indicator values to two decimal places, to ensure data consistency and accuracy.
Responsibility allocation: Designate a dedicated person to be responsible for data collection from various data sources, such as production line quality inspectors responsible for process quality inspection data, customer service personnel collecting customer feedback data, and the procurement department coordinating supplier inspection data

• 统计分析方法运用：运用统计工具，如均值、中位数、标准差分析质量指标的集中趋势和离散程度；绘制柏拉图找出主要质量问题及占比，用鱼骨图分析问题产生的原因。
• 建立质量指标体系：设立关键质量指标（KPI），如产品合格率、次品率、客户投诉率等，设定目标值并对比实际数据，分析偏差原因。
• 趋势分析：通过绘制折线图、柱状图等，观察质量指标随时间的变化趋势，预测潜在质量风险。

Application of statistical analysis methods: Use statistical tools such as mean, median, and standard deviation to analyze the central tendency and dispersion of quality indicators; Draw Plato to identify the main quality issues and their proportions, and use fishbone diagrams to analyze the causes of the problems.
Establish a quality indicator system: Establish key quality indicators (KPIs) such as product qualification rate, defect rate, customer complaint rate, etc. Set target values and compare them with actual data to analyze the reasons for deviations.
Trend analysis: By drawing line charts, bar charts, etc., observe the trend of quality indicators over time and predict potential quality risks.

• 报告内容：包含本月质量数据汇总、各项质量指标达成情况、主要质量问题及分析、改进措施执行进度（若有上月遗留问题）。
• 可视化呈现：运用图表、图形直观展示数据，如用饼图展示不同缺陷类型占比，用雷达图对比不同产品线质量指标。
• 报告模板：设计标准化报告模板，确保格式统一、内容完整，方便管理层审阅和对比分析

Report content: including summary of quality data for this month, achievement of various quality indicators, main quality issues and analysis, progress of improvement measures implementation (if there are any outstanding issues from last month).
Visual presentation: Use charts and graphics to visually display data, such as using pie charts to show the proportion of different defect types, and using radar charts to compare quality indicators of different product lines.
Report Template: Design standardized report templates to ensure uniform format and complete content, facilitating management review and comparative analysis.

• 问题解决机制：针对分析出的主要质量问题，成立专项改进小组，制定详细的改进计划，明确责任人、时间节点和预期效果。
• 预防措施制定：根据趋势分析和潜在风险，制定预防措施，如优化生产工艺参数、加强员工培训、完善供应商管理等，防止问题再次发生。
• 效果跟踪评估：定期跟踪改进措施的执行情况，评估效果，对比改进前后质量数据，验证措施的有效性。

Problem solving mechanism: Establish a special improvement team to address the main quality issues identified through analysis, develop detailed improvement plans, clarify responsible persons, timeline, and expected results.
Preventive measures formulation: Based on trend analysis and potential risks, preventive measures are formulated, such as optimizing production process parameters, strengthening employee training, improving supplier management, etc., to prevent problems from happening again.
Effect tracking and evaluation: Regularly track the implementation of improvement measures, evaluate their effectiveness, compare quality data before and after improvement, and verify the effectiveness of the measures.
