  1. What is 7 Waste Lean Principle: All waste is eliminated • 7 Types of Waste • Correction • Overproduction • Movement of Material & Information • Waiting • Inventory • Processing

  2. # 1 What is Lean Manufacturing? (Overproduction is the most significant form of waste!) Overproduction • There are 2 types of over-production: both are wasteful. One is producing a larger amount than the order requires. The other is producing goods at a rate faster than they are needed.

  3. #2 What is Lean Manufacturing? Correction • When work is not performed correctly the first time, resources are used to correct the defect. Resources are used again and again to address quality problems that may surface later

  4. #3 What is Lean Manufacturing? Motion • Any movement of people or machinery, which does not contribute added value to the product is considered waste.

  5. #4 What is Lean Manufacturing? Material Movement • Applies to the delivery of materials and parts to the supply of information. Any movement of material and product that does not support the “Just-In-Time” production is a form of waste.

  6. #5 What is Lean Manufacturing? Waiting • This is “idle” time that occurs in process line that is not efficiently organized; or when an operator must wait for a machine to complete an automatic process or for the delivery of parts to the workstation.

  7. #6 What is Lean Manufacturing? Inventory • Inventory must be adjusted to the actual need or the “JUST-IN-TIME” production schedule. An excess of parts between work processes or too many parts delivered by suppliers is considered waste.

  8. #7 What is Lean Manufacturing? Processing • Unnecessary processing of work does not improve the quality of the product.

  11. Process Mapping

  12. Objectives • Understanding the use of Process Mapping. • How to construct a Process Flow Chart.

  13. Process Mapping • Process Map is a graphical presentation of the flow of a process. A detailed process map contains information that is beneficial to improving the process

  14. OPERATION INSPECTION TRANSPORTATION DECISION STORAGE

  15. Basic Process Flow Scrap Bad Bad Good Good • How many Operational Steps are there? • How many Decision Points? • How many Measurement/Inspection Points? • How many Re-work Loops? Warehouse

  16. Let's Practice... ... Draw a process flow on what you do in the morning before coming to work/Class...
