3Lean Explained
Lean A principle driven, tool based philosophy
that focuses on eliminating waste so that all
activities/steps add value from the customers
perspective.
Lean is all about continuous waste elimination
Strive for State Government processes with
- Higher customer satisfaction
- Shorter lead time
- Higher flexibility
- Higher quality
- Lower costs
- Higher employee satisfaction
4Lean Benefits
Cycle Time
Wait Time (non value add)
Before
After
Work Time (value add)
Same work completed in less time
- Productivity
- Customer satisfaction
- Profit
- Customer responsiveness
- Capacity
- Quality
- Cash flow
- On time delivery
- Cost
- Defects
- Lead time
- Inventory
- Space
- Waste!
Cost/Chaos
Cycle time
Relentlessly focus on reducing non-value adding
activities
5Five Lean Principles
Map all of the steps value added and non-value
added that bring a product of service to the
customer
Define value from the customers perspective and
express value in terms of a specific product
2 Map the Value Stream
1 Specify Value
3 Establish Flow
5 Work to Perfection
The continuous movement of products, services and
information from end to end through the process
The complete elimination of waste so all
activities create value for the customer
4 Implement Pull
Nothing is done by the upstream process until the
downstream customer signals the need
The tools get you there the principles keep you
there
6Five Lean Principles
A capability provided to a customer at the right
time at an appropriate price, as defined in each
case by the customer.
1. Specify Value
- Waste
- Activities that add no value, add cost and time
- Symptoms need to find root causes and eliminate
them - 7 types of waste
- (Unnecessary) inventory
- Overproduction
- Waiting
- Transporting
- Inappropriate processing
- Unnecessary motion
- Defects
- Specify value from the standpoint of the end
customer - Ask how your current products/services and
processes disappoint your customers value
expectation - price?
- quality?
- reliable delivery?
- rapid response to changing needs?
- fundamental definition of the product?
Typical operation 1-10 of activities are
value-adding
7Five Lean Principles
Whenever there is a product or service for a
customer, there is a value stream. The challenge
lies in seeing it. (Womack, Learning To See)
2. Map the Value Stream
Value stream
- Identify all of the steps currently required to
move products from order to delivery - Challenge every step Why is this necessary?
Would the customer think the product is worth
less if this step could be left out? - Many steps are only necessary because of the way
firms are organised and previous decisions about
assets and technologies
All activities, both value added and non-value
added, required to bring a product (or provide a
capability) from raw material (initialisation)
into the hands of the customer
Map the value stream see the whole and improve
the system
8Stage 2 continued Value Stream Mapping
Current
Future
Identify opportunities from the value stream map
9Five Lean Principles
3. Establish Flow
Line up all steps that truly create value in a
rapid sequence
- Require that every step in the process be
- Capable right every time (six sigma)
- Available always able to run (TPM)
- Adequate with capacity to avoid bottlenecks and
overcapitalisation (right-sized tools)
- Continuous movement of products, services and
information through the various transactions from
end to end in the process - Flow appears impractical and illogical because we
have been trained to think in terms of - departments, silos
- batches, queues
- efficiencies and backlogs
Batch Processing 1 minute per piece
Continuous Flow Make One Move One
Cycle Time 30 min
Cycle Time 12 min
Apply the right tools at the right stage
10Five Lean Principles
4. Implement Pull
Nothing is done downstream until required upstream
- Through lead time compression correct value
specification, let customers get exactly whats
wanted exactly when its wanted - At the pull of the customer/next process
- Using signals (kanbans)
- A system of cascading production and delivery
instructions in which nothing is done by the
upstream supplier until the downstream customer
signals the need
Okay
Pull customer-centric
11Five Lean Principles
5. Work to Perfection
A continual cycle of process improvements
- There is always some waste that can be removed
- People learn and exercise more creativity
- - Involve employees in the process, training them
as you proceed - Continuous improvement leads to innovation
- Use root cause analysis to solve problems
promptly and permanently. - Make objectives visible

12Common Lean Tools 5S
5S a framework to create and maintain your
workplace
1. S SORT (Organisation)Distinguish between
what is and is not needed
2. S SET IN ORDER (Orderliness)A place for
everything and everything in its place
3. S SHINE (Cleanliness)Cleaning and looking
for ways to keep it clean
4. S STANDARDISE (Adherence)Clearly define
Tasks and Procedures
5. S SUSTAIN/SYSTEMISE (Self-Discipline)Stick
to the rules, scrupulously
Implementing the 5S is often the first step in
lean transformation
13Common Lean Tools Standardised Work
Why have standardised work? Waste
Elimination
- To make process rules explicitEstablish the
explicit methods for manual tasks with respect to
quality, quantity, cost and safety.
prevent wastes
- A tool for improvementThere can be no
improvement in the absence of standards. Abnormal
situations show that something is going on.
expose wastes
14Common Lean Tools Standardised Work
The devil is in the details. If you do not
specify the standard, you allow wastes to occur
that could be eliminated. But more important, it
hinders learning and improvement in the
organization. Specify content, sequence, timing
and outcome to prevent and to expose waste.
However, keep in mind that the details have to
improve the flow of value as drawn in a value
stream map.
Perfect example of standardised work
- Each worker understands their task.
- All tools and equipment are at arms length
- Standard work has been practiced to perfection
- Continuous observation and analysis drives
continuous improvement - Types of Waste Eliminated
- Searching
- Finding
- Selecting
- Transporting
- Waiting
15How to How to Make Lean Successful at Your Dept
16Success Factors
- Organisations maintaining long-standing,
comprehensive process improvement programs share
common features that enhance their ability to
sustain the efforts. They have - Been inspired by influences emanating outside of
the public sector, usually a leader with business
experience - Experienced little leadership turnover
- Paved the way for the programs implementation by
removing organizational barriers and modifying
its culture - Focused on certain underlying principles and
maintain a consistent conceptual framework - Begun by employing a full-time administrator to
oversee the programs implementation - Offered a guarantee to employees that no layoffs
will result from a process improvement project - Made conscious efforts to communicate program
successes internally - Maintained reasonable expectations did not
achieve success overnight, with most taking
several years to create a culture that
characterizes and sustains their program.
Active leadership in both words and actions is a
must

17How Has the Improvement Program been Sustained?
- These organisations create an infrastructure
supporting the combined Lean/Six Sigma program
with attention to four goals - 1. deploy a sound, consistent, and robust
methodology - 2. build trust by removing fear
- 3. initiate long-term cultural change
- 4. communicate the vision to all stakeholders.
