LEAN MANUFACTURING OVERVIEW
“Lean Manufacturing” incorporates tools and techniques to
Optimize time, human resources and assets
Improve productivity
Improve quality of products and services

5. Page 5 of 21Presented by: Sh VRM
Lean production focuses on
- Eliminating waste in processes
- Expanding capacity by reducing costs and shortening
cycle time
- Understanding what is important to the customer
Analyze the flow of information and materials for
continual improvement of the process
LEAN MANUFACTURING OVERVIEW

There are three types of operations in any process
Non-Value-Adding (NVA)
Necessary but Non-Value-Adding (NNVA)
Value-Adding (VA)
Focus on Value-Adding (VA) operations
WASTE REMOVAL

Kaizen
Focus on eliminating waste, improving productivity and
achieving sustained continual improvement
• Six Sigma
A statistical process control and analytical tool to improve
productivity and quality.
Total Productive Maintenance (TPM)
Basket of Maintenance of Practices which helps in focusing
on elimination losses such as breakdowns, idling and minor
stoppages, reduced defects & rework, spills and process-upset
conditions

Cellular Manufacturing/One-Piece Flow system
Process for connecting the manual and machine processes of
similar operations in order to eliminate non-value adding
activities.
Just-in-time (JIT) Production Systems / Kanban
Inventory strategy to reduce process inventory and it’s
associated costs.
Value Stream Mapping
Created a visual representation of all product and information
flows from raw material to shipping

5S
Reduces waste and optimizes productivity through
maintaining an orderly workplace. Elements of 5S are
Seiri – Sort
Seiton – Set in Order
Seiso – Shine
Seiketsu – Standardize
Shitsuke – Sustain
Place for everything and everything in it’s place.

1. Understanding waste in the form of loss of contribution at
every stage of operation.
2. Understanding the impact of HSE incidence on
contribution.
3. Understanding all components of cost of production.
4. Understanding of value added activities and non-value
added activities.
5. Understanding Process intensification.
6. Understanding EPS and Marketing functions.
