You should be able to: Explain what is meant by the term lean operations system List each of the goals of a lean system and explain its importance List and briefly describe the building blocks of lean List the benefits of a lean system Outline the considerations important in converting a traditional mode of operations to a lean system Point out some of the obstacles that might be encountered when converting to a lean system Describe value stream mapping Student Slides 14- Lean operation A flexible system of operation that uses considerably less resources than a traditional system Tend to achieve Greater productivity Lower costs Shorter cycle times Higher quality Student Slides 14- The ultimate goal: Achieve a system that matches supply to customer demand; supply is synchronized to meet customer demand in a smooth uninterrupted flow A balanced system One that . | JIT and Lean Operations McGraw-Hill/Irwin Copyright © 2012 by The McGraw-Hill Companies, Inc.
