Study Notes
Lean Thinking and Production
- Primary concern of Lean thinking:
- Work-in-progress (WIP) inventories are positioned in a way that minimizes waste and maximizes workflow in Lean layouts.
Lean Production Scheduling
- Emphasizes:
- Production scheduling in Lean Production emphasizes continuous flow, small batches, and minimizing waste.
Lean Supply Chain Relationships
- Firms are encouraged to work closely with suppliers and customers, sharing information and collaborating to reduce waste and improve efficiency.
- Communication is key, with smaller, more frequent purchase orders sent to suppliers.
Six Sigma and Continuous Improvement
- Purpose of continuous improvement:
- Continuous improvement aims to reduce defects, variations, and wastes, and to improve overall quality.
Six Sigma Tools and Phases
- Role of flow diagrams:
- Purpose of Pareto charts:
- 'Define' phase primarily involves:
- 'Control' phase primarily involves:
Workforce Empowerment
- Emphasis on workforce empowerment:
- Empowered workforce is essential for Lean Production and Six Sigma, as it encourages employee involvement and accountability.
Inventory Management
- Significance of lower safety stocks:
- Lean Production reduces inventories and material movements by minimizing waste, producing in small batches, and using a pull-based system.
Lean Production Goals
- Main goal of Lean Production:
- Reduces waste, improves quality, and increases efficiency.
Test your knowledge about the Lean Production system, an operating philosophy emphasizing minimal inventory levels, faster delivery times, and improved quality by focusing on high-quality inputs and streamlined processes. Learn about the key elements of Lean Production and its origin as the Toyota Production System (TPS).
