Lean Methodology

Lean methodology is a systematic approach to business and process management that emphasizes creating maximum value while minimizing waste. Originally developed from Toyota Production System, lean thinking has evolved into a comprehensive framework applicable across industries.

Core Principles

1. Value Definition

   • Identify what customers truly value
   • Eliminate features and processes that don't contribute to value
   • Align operations with customer development insights

2. Value Stream Mapping

   • Document all steps in the process
   • Identify bottlenecks and inefficiencies
   • Distinguish value-adding from non-value-adding activities

3. Flow Optimization

   • Create smooth, continuous workflows
   • Minimize work-in-progress
   • Reduce batch processing where possible

4. Pull Systems

   • Implement just-in-time production
   • Respond to actual demand rather than forecasts
   • Reduce inventory and overhead costs

5. Continuous Improvement

   • Foster a culture of kaizen
   • Implement regular feedback loops
   • Empower team problem-solving
