Mindset of lean


Refer to the above mind map, the structure of lean manufacturing can be disassembled as below,
1 Lean spirit
1.1 Continuous improvement
1.2 Respect to people

2 Objectives of lean
2.1 Eliminate waste
2.2 Create value
3 Main duty of lean
Create a continuously flow of process, material and information.

4 Lean tools
4.1 Standardization and Standard works
4.2 Just in time (JIT) and Pull system
4.3 Mistake proofing and autonomation
4.4 Visual management and Kanban system
4.5 OEE and TPM
4.6 5S
4.7 Tact time
4.8 Value-added and non-value-added, 7 wastes

If we need to describe LEAN in simply, I would like to describe that as,
"Continuous improvement and Respect to people are the spirits of lean. All the actions must be taken under the guideline. The improvement activities are carry out through setup the continuously flow to eliminate the different kinds of wastes, and use the saved resource to create value. During setup the continuously flow, it needed to apply different kinds of lean tools. "
思维图是一种帮助理解及记忆的工具,最近因为要协助各部门加深了解精益生产的概念与结构,已绘制一个精益生产思维图如上.

思维图解释:
于图的上部,代表精益生产的最主要两个精神,即是(一).持续改善;(二).尊重人性(以人为本);这种精神必须贯通整个精益生产的运作,才能有效的发挥其优点.
于图的中部,从左到右代表从精益生产推动开始,以建立一个无间断的流程为手段,以达到精益生产的两个主要目的.(一)消防浪费;(二)创造价值.
于图的底部,就是代表各种用以建立无间断流程的主要工具,其中各项工具已于日常生产运作中应用,如全员生产维护,快速换模系统,防错系统,自动化,目视管理,看板系统,拉运系统,生产预备,生产均衡化及标准化等.而各工具之间,亦起了紧密的协同作用.若无间断流程欠缺了这些工具,都不能达到理想中的要求.

各位,若能理解此思维图的意义,基本上对于精益生产就有一定程度的理解了.对于以后各位推动精益生产亦有不少帮助.
