What is Standard WIP 什么是标准WIP
Process WIP 制程WIP
WIP within same process with low variation of cycle time同一个制程中的WIP,周期时间CT变化很小
It is all that WIP in the same process, not categorized as Standard WIP or PTP WIP. 所有在同一个制程中的WIP,不是标准WIP或制程间WIP.Example:- 例如 Before Kaizen, Manual Insert (MI) Line Process WIP =9 pcs. After Kaizen MI Process WIP is 3. Standard WIP for each station is 1pc. 改善前，插件拉的制程WIP=9 pcs。改善后插件拉制程 WIP=3pcs。每个工位的标准WIP为1pcs.
