Lead Time 制造周期
Definition:定义: Total time required to complete one unit of a product or service. 完成一个产品或提供一项服务 所需的总时间.
Graphic Tool Process图表工具程序
The Lead Time Reduction Process:缩短周期程序: 1. Identify the product/service you provide. 分清您所提出的产品,服务. 2. List all steps required to complete product, from start to finish.列出从开始到完成一个产品所需的所有步骤. 3. Identify time now required to complete each step. 弄清完成每一步骤现在所需的时间. 4. Identify steps that add value to the product. 弄情使产品增值的各个步骤. 5. Graph process (see graphic tool ex. to right). 图示程序(见右图). 6. Analyze & eliminate time needed for non-value added (揘VA? steps.分析和消除非增值步骤所需的时间. 7. Analyze & reduce time needed for value-added (VA steps.分析和缩短增值步骤. 8. Graph this process.图示改进后的过程. 9. Identify the 搃deal?process (ideal = minimum time for 揤A?steps with no 揘VA?steps).识别"理想"程序 (理想=使增值步骤时间尽可能短,无增值步骤. 10. Graph ideal process & work to achieve it. 画出理想程序并努力去实现. Directions for use of graphic tool: 使用制图工具说明: Make one box for each step每步用一方格表示 Make box height roughly proportional to time required for step 根据所需时间精定方格高度 Put VA boxes on left增值方格放在左边 Put NVA boxes on right 非增值方格放在右边 Put boxes in correct order方格顺序正确 Label boxes (name of step and time required)给方格打标记(每步名称和所需时间)

Purpose of Lead Time Analysis 分析制造周期的目的
To document all steps in a process 记录过程中的每一个步骤 To quantify the time and distance of each step in a process 测 量过程中每一个步骤所需的时间和距离 To identify where value is being added to the process 识别过程的增值步骤 To understand how non-value added activities drive cost in a process 了 解 非 增 值 步 骤 是 怎 样 增 加 过 程 成 本 的 To learn that reducing Lead Time contributes directly to improving Q,S,T, P and Customer Satisfaction. 理 解 制 造 周 期 的 缩 短 将 直 接 改 善Q.S.T.P. 和 客 户 的 满 意 程 度
