What is Lean Management?
Lean Management is a philosophy that seeks to eliminate
waste in all aspects of a firms production activities:
human relations, vendor relations, technology, and the
management of materials and inventory.
Lean Management was developed by the Japanese
automotive industry, with a lead from Toyota and utilising
the Toyota Production System (TPS), following the
challenge to re-build the Japanese economy after World
War II.

How does Lean Management work?
Considers an end to end value stream that delivers
competitive advantage.
Seeks fast flexible flow.
Eliminates/prevents wastes (Muda).
Improve Quality.
Helps in reducing costs.
Increased Productivity.

5 Principles of Lean Management
Value - specify what creates value from the customers
perspective.
The value stream identify all the steps along the
process chain.
Flow - make the value process flow.
Pull - make only what is needed by the customer (short
term response to the customers rate of demand).
Perfection - strive for perfection by continually attempting
to produce exactly what the customer wants.

Syed Zeeshan Arshad - BE Industrial & Manufacturing
Types of Activities
Production operations - can be grouped into following three
types of activities
Value-added activities - Activities that changes the size,
shape, fit, form or function of material or information as to
satisfy customers demands and requirements.
Non value-added activities - That consume resources but
do not meet the customers demands or requirements
Necessary non value-added activities - Dont add value
from the perspective of the customer but are necessary to
produce the product unless the existing supply or
production process is radically changed.

Waste
Anything that adds costs
to the product without
adding value

Syed Zeeshan Arshad - BE Industrial & Manufacturing
Ohno Defined Seven types of Waste (MUDA)
Over-Production
Defects
Inventory
Motion (Man/Machine)
Over-Processing
Transportation (Material)
Idle Time

Over-production
Producing
What is unnecessary
When it is unnecessary
And in an unnecessary amount
Worst of All Types of Wastes as it hides other
wastes (Waiting, Movement, Transportation)
Taiichi Ohnos 7 Wastes

Syed Zeeshan Arshad - BE Industrial & Manufacturing
Defects
Physical defects which directly add to the costs of goods sold:
Inspection
Customer complaints
Scrap/Rework
Also Includes:
Errors in paperwork
provision of incorrect information about the product
late delivery
production to incorrect specifications
Results in Disruptions to the smooth flow and generates
bottlenecks

Inventory
Unnecessarily high levels of:
Raw materials
Works-in-Progress(WIP)
Finished Goods
Symptoms of a Sick Factory
Extra inventory leads to:
higher inventory financing costs
higher storage costs
higher defect rates
Taiichi Ohnos 7 Wastes
10
Syed Zeeshan Arshad - BE Industrial & Manufacturing
Motion
Major part of a typical workers work Includes
unnecessary physical motions
Too fast or slow movements
Difficult physical movements, due to poorly designed
ergonomics, which slow down/strain the workers

Over-processing
Unintentionally doing more processing work than
required
Typically performed in the name of Quality May also
include setup and Changeover
Taiichi Ohnos 7 Wastes
12
Syed Zeeshan Arshad - BE Industrial & Manufacturing
Transportation
Any movement of materials such as
Moving materials between workstations
Picking up/ setting down items
Ideally, output of one process should be immediately
used as the input for the next process
Transportation between processing stages results in:
Prolonging production cycle times
Inefficient use of labor and space (source of minor
production stoppages)

Idle Time
Time spent waiting for something by:
Operator (Material, Tooling)
Machine (Previous Operation, Inspection, Monitoring)
Bottlenecks or inefficient production flow on the
factory floor
Results in a significant cost as it increases labor costs and
depreciation costs per unit of output

Syed Zeeshan Arshad - BE Industrial & Manufacturing
Sources of Waste
Layout (distance)
Long setup time
Incapable processes
Poor maintenance
Poor working methods
Lack of training
Lack of adherence
Ineffective scheduling
Poor supervisory skills
Inconsistent performance
measures
Functional organization
Excessive controls
No back-up / cross
training
Unbalanced workload
No decision rules
No visual control
Supplier quality
Lack of workplace
organization

7 Service Wastes
Delay customers waiting for service.
Duplication having to re-enter data, repeat details
etc.
Unnecessary movement - poor ergonomics in the
service encounter.
Unclear communication having to seek clarification,
confusion over use of product/service.
Incorrect inventory out of stock.
Opportunity lost to retain or win customers.
Errors in the transaction, lost/damaged goods
