Study Notes

Lean Management of Production

Lean concept introduces a short presentation about lean system and methods
Lean method aims to eliminate production waste in various forms
Henry Ford, Kiichiro Toyoda, Taiichi Ohno, Womack, Jones, and others have contributed to lean methodologies

Historical Development of Lean Production

Eli Whitney (1798) and other pioneers contributed to quality management and production improvement (refer to Figure 1)
Henry Ford (1863-1947) pioneered flow production in 1913 which revolutionized factory production
Ford introduced principles of standardization, operational efficiency, effective production flow and economies of scale
Ford's innovations focused on special purpose machinery, Go No Go gauges, and precise products, making assembly easier

Definition of Lean Production

Lean Production is a systematic approach meant to eliminate sources of waste and delays, maximizing the value added by a company's activities.
Lean thinking encompasses the broader scope of lean production, incorporating distribution and other functions beyond the factory
Lean production aims for efficiency of workers and work cells
Toyota Production System (TPS) is a collection of efficiency improvements by Toyota Motors to remain competitive and survive after World War II.

Principles of Lean Production

Identify Value: The organization must realize customer-determined value of the good or service produced, constantly striving to meet their expectations
Map the Value Stream: Understanding all processes from raw materials to customer delivery is required. Eliminate processes that don't add value
Create Flow: Smooth production flow without bottlenecks, delays, or interruptions to ensure nothing is produced ahead of customer orders is required
Establish Pull: Production is based on actual customer orders (just-in-time), avoiding excess inventory and ensuring the right quantities are produced at the right time
Seek Perfection: Continuous improvement (Kaizen) is key to eliminating waste to achieve perfect quality by eliminating defects

Eight Deadly Wastes (Muda)

Defects: Poor quality, needing rework or replacement
Overproduction: Producing more than needed, causing unnecessary inventory
Waiting: Delays in the production process
Not Utilizing Employees: Underutilizing employee skills or knowledge
Transportation: Unnecessary movement of materials, supplies or personnel
Inventory: Excess stock of raw materials, work-in-progress, or finished goods leading to storage issues
Motion: Unnecessary movement of people or equipment
Excess Processing: More processing or steps than needed by the customer
