Study Notes

Lean Enterprise

A lean enterprise emphasizes the prevention of waste throughout the organization
Waste is defined as any extra time, labor, capital, space, facilities, or material that does not add value to the product or service for the customer

Signals and Kaizen

Signals are used to alert people about problems
Kaizen encourages the continual activity of small process improvements by operators
Kaizen Blitz is a highly focused action-oriented 3-5 day improvement workshop by a multifunction team to improve a specific process

Value Stream

A value stream is the specific flow of activities required to design, order, produce, and deliver a product or service to customer(s)
There may be more than one value stream in an organization
Ideally, it will only include value-added activities

Value Stream Map (VSM)

VSM graphically describes the sequence and movement of activities
First, develop a current state map, then an ideal state map with only added activities
The difference between the two provides opportunities for improvement

Theory of Constraints (TOC)

TOC states that one operation limits the throughput of the system at any one time
Improving this operation will improve the entire system's efficiency

Historical Review of Lean

Adam Smith - Division of Labour theory
Eli Whitney - Standard parts
Gilbreth - Process map and motion efficiency
Taylor - Principals of scientific management
Ford Motor Company - Speed and flow (1920)
Toyota Production System - Flexibility and complexity management
Deming Concept - Quality @ Source
Womack and Jones - Lean fundamentals (1990)

Lean Fundamentals

Types of waste: non-value added and unnecessary, necessary but non-value added, variation, and overstressing
Categories of waste: overproduction, waiting, transportation, defects, inventory, motion, and extra processing
Workplace Organization - 5 S's: sort, straighten, shine, standardize, and sustain
Concept of Flow: continuous with a minimum of variation, reduces time between order and delivery
Inventory Control: JIT, Kanban, and Takt time
Visual Management: visual displays to inform people about customers, projects, performance, goals, etc.
