Overview of Lean Principles
Overview of Lean Principles
• Origin
- Derived from the Toyota Production System (TPS)
focused on minimizing waste in the production
process
• Fundamentals
-

A Practice?
A Process?
• Answer: All of the Above
- Many ideas and philosophies and how to get
there.
Process Industries – Specific Features
Process Industries – What are They?
• Industries Categorized as Types
- Discrete – Typically Assembly Manufacturing
• Finished product can be broken down to the original
parts
- Automotive
- Electronics
- Tools
- Process – Flow Production, Reactive Production
consisting of formulas and recipes
• Once it is put together, you cannot take it apart

Process Industries – Key Characteristics
• Dynamics of Process Manufacturing
-
Volume and Variety
Capital (Equipment ) Versus Labor
Processes are Difficult to Stop and Start
Setups and Changeovers are Complex
Inventory Focus – Finished Product versus WIP
Inventory Accessibility (Hidden WIP)
Material Flow Patterns Production Process
• Flow patterns are reversed between process and
discrete

Summary – Key Characteristics of Process Industries
• Typically Fewer Raw Materials
• Dependent on Raw Natural Resources
• Equipment Typically Much Larger
• Equipment a Higher Impact on the Process
• High Degree of Product Differentiation
• Process Step based not Work Center based
Identifying Wastes in Process Industries
Identifying Wastes in Manufacturing
• Waste is the Major Principle of Lean and TPS
- Identifying and eliminating waste is the key to
raising productivity.
• Waste with Relationship to Costs
- Equating Waste with Customer Value
- Categorizing Waste
• People
• Material
• Time
Identifying Wastes in Manufacturing
• Categories of Waste
-
Waste of Overproduction
Transportation Waste
Waste of Time (Waiting Periods)
Processing Waste
Waste of Inventory
Waste of Movement
Wasted of Defective Material, Yield Loss
Categories of Waste
• Overproduction - Making more product than
demand requires
- Batch Size or Campaign Size Practices
- Process Variations
• Transportation - All movement of materials within
the manufacturing operation
- Disconnected Material Flow
- Specialty Storage Areas
- Facility Design
Categories of Waste
• Time (Waiting Periods) – Time waiting for
material to arrive
-
Material Delivery
Curing/Hold Time
Inspection Time
Start Up Time
Categories of Waste
• Processing – Wastes in the Process
-
Processing necessary to identify potential issues
Inspection
Testing
Laboratory Operations
Rework Operations
• Inventory – Technically all in-process inventory is
waste
-
Minimize excess amounts
Synchronizing production steps
Rate Synchronizations
Bottleneck Issues
Leftover Material – Heels
Campaign Sizes
Categories of Waste
• Movement – People Movement, moving
from station to station
- Time to move through the facility
- Operators moving from step to step
• Defect Material, Yield Loss – Out of spec
materials to process or customer standards
-
Wrong Thickness
Incorrect Potencies
Fat Content
Quality Defects
Summary - Identifying Wastes in Process Manufacturing
• Major Lean Principle is Waste
- Identifying and Eliminating Waste Key to Successful
Lean Practices
- Wastes can be detected in both discrete and
process environments
• Wastes Can be Segmented into Categories
• Waste is anything that can be measured by value
• Value is also Categorized
- Value to the Business
- Value to the Customer
Applying the Lean Tools in Process Manufacturing
Lean is a Concept, Practice and Philosophy
• There are a Variety of Tools or Practices to
enable the Lean Concept
• Traditionally, Lean focused on Discrete
Production
• Most of the Traditional Lean Tools can be
Applied to Process Manufacturing
Lean Tools for Process
• The Traditional Lean Tools are:
-
Mapping of your processes
Time Management
Continuous Improvement
Organization
Quality
Minimizing Errors
Problem Solving
Lean Tools for Process
• Value Stream Mapping – Visual Diagram
- Process Steps
- Flow of Materials, Activities and Time for Each Step
Lean Tools for Process
• Takt Time
- Time Mapping
- Time interval in which each process step must be completed
to meet customer demand
- Processing Time
- Hold/Quality Time
• Kaizen
- Japanese term for continuous improvement
- Process of constantly looking for improvements in processes
- Kaizen is a philosophy
Lean Tools for Process
• 5S – Five Step Process for organizing all areas of the workplace
Lean Tools for Process
• Jidoka
- One of the two Pillars
- Philosophy of Quality
- If a Quality Issue is detected, activities stop until it is
resolved
Lean Tools for Process
• SMED – Single Minute Exchange of Dies
- Philosophy of analyzing all steps to a changeover, setups
- Minimize Time and Material Waste
- Decreasing changeover time
• Poka-Yoke
-
Techniques for minimizing mistakes
Prevention of defective products, bad yields
Prevent equipment from being setup incorrectly
Sensors
Color Coding
Lean Tools for Process
• Five Whys – Always ask Why?
-
Philosophy of asking questions to solving a problem
Continue to ask questions
How did a problem occur?
Questions about the solutions so it is a sound solution
• Standard Work
-
Specific tasks to be performed in each production step
Operational sequence
Timing
Referred to as “SOP”s, Standard Operating Procedures
Lean Tools for Process
• TPM – Total Productive Maintenance
- Practices of improving how is equipment is operated and
maintained
Lean Tools for Process
• Cellular Manufacturing
-
Dividing the process into families that require similar steps
Improves Quality
Reduces Changeovers
Reduces Variability
Improves Throughput
• Heijunka
- Production Leveling or Production Smoothing
- Load Leveling
- Product Wheel
• Kanban
- Process for visually signaling what is needed
- What needs to be produced to replace what the customer has
purchased
Lean Tools for Process
• Just-In-Time
-
One of the two Pillars
Make What is Needed
Make it When it is Needed
Make the Exact Quantity Needed
Summary - Lean Tools for Process Manufacturing
• Lean Tools focus on:
-
Minimizing Waste
Minimizing Mistakes
Maximizing Utilization
Cost Effectiveness
Better Service to the Customer
Empowering Team Members
• These can be applied to any type of operation
• In Essence: Common Sense Business Practices
