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.
