The Three Step ApproachIntegrating Principles and Tools“三步”法综合理论和工具Johnson Controls Manufacturing System3 Step Approach_SHW_E_Sep 现实?10% 关于技术10% Technical?90% 关于人90% About PeopleThe principles of Lean can most likely be absorbed in a one half day classroom session!精益制造的理论非常可能在一天半的课堂教学里就掌握!The difficult part is putting the principles into practice!困难的是在实践中应用这些理论!3 Step Approach_SHW_E_Sep 3 Steps Process“三步”法?Stabilize稳定化?Standardize标准化?Simplify简化3 Step Approach_SHW_E_Sep ?People人?Process过程?Product 产品Instability – 3 sources不稳定的三个来源3 Step Approach_SHW_E_Sep Instability?关键是尽可能使人员对精益的改变都保持一致。Making sure people are as consistent as possible is key to any lean conversion.?为什么会有人旷工/人员流动Absenteeism / turnover- (Why are people gone?)?反对改变Resistance to change?反馈--(交流–计划vs. 实际)Feedback-(Communication –Plan vs Actual)?过度信赖技能水平(高度的重复,复杂性等)Over-reliance on skill level (high repetition, complexity, etc)?超负荷劳动(需要轮班)Overburdened (Rotation needed)?知识水平(我们提供了什么培训?)Knowledge level (what training have we provided?)?没有遵守规则Not following rules3 Step Approach_SHW_E_Sep Instability?你的过程靠什么保证每次都执行的方法都是相同的?What keeps your process from being performed the same way, every cycle? ?标准化工作做的不好或者没有做到。Poor or missing Standardized Operations?布局正在变更或处于不断变化之中Layouts changing or in flux?太多零件。。。太少零件Too many parts….. Too few parts?工作单元设计的不够好Poor work cell design?设备是不可靠的/不可重复的Machines that are unreliable / unrepeatable?工作单元有差异Work cells that allow for variation?很难说什么样是正常状况Hard to tell what ‘Normal’ looks like?缺乏好的防错Lack of good Errorproofing3 Step Approach_SHW_E_Sep Instability?是什么产品特征让我们的过程有困难。What Product features make our process difficult? ?我们的系统有缺陷Defective parts in our system?零件随环境状况而变化Parts that change with the environmental conditions?零件搬运困难(烫手的零件,刷油漆的零件)Parts that are difficult to handle (hot parts, painted parts)?零件不好配合或需要返工Parts that fit poorly or need rework?需要检验Inspection required?需要重新设计(D
