Lean Manufacturing

Lean Manufacturing Overview

Lean Manufacturing is a systematic approach to minimizing waste within a manufacturing system without sacrificing productivity, focusing on creating more value for the customer with fewer resources.

Key Principles

  • Value
  • Value Stream
  • Flow
  • Pull
  • Perfection

Waste Elimination

  • Defects
  • Overproduction
  • Waiting
  • Non-Utilized Talent
  • Transportation

Benefits

  • Reduced Costs
  • Improved Efficiency
  • Enhanced Quality
  • Increased Customer Satisfaction
  • Better Resource Utilization

Types of Waste (TIMWOODS)
