Lean Principles: Goals and Waste

• Lean principles, goals, and wastes are key concepts in process improvement.

5 Principles of Lean

• Identify Value: Understand what the customer values and focus on delivering that value.
• Map the Value Stream: Analyze material and information flow to identify non-value-added steps (waste).
• Create Flow: Eliminate interruptions and bottlenecks for smooth, continuous processes.
• Establish Pull: Produce based on actual customer demand, avoiding overproduction based on forecasts.
• Pursue Perfection: Continuously improve processes to eliminate waste and enhance value.

4 Goals of Lean

• Improve Quality: Build quality at every step to reduce errors and defects.
• Eliminate Waste: Identify and remove activities that do not add value.
• Reduce Lead Time: Speed up order-to-delivery processes.
• Reduce Cost: Achieve efficiency by eliminating waste and continuously improving.

8 Wastes of Lean (DOWNTIME)

• Defects: Errors causing rework or scrap.
• Overproduction: Producing more than needed or too early.
• Waiting: Idle time caused by process flow delays.
• Non-utilized Talent: Not using employees' skills, ideas, or capabilities.
• Transportation: Unnecessary movement of materials or products.
• Inventory: Excess materials or products not being processed.
• Motion: Unnecessary movement of people (e.g., walking, reaching).
• Extra Processing: Doing more work or using more materials than required (e.g., polishing something twice).
