What is Lean Office?
Lean Office is a systematic
approach applied to the value
chain with an aim to streamline
the business processes by:
» Eliminating waste
» Utilizing lean techniques
» Resulting in: Lead time
reduction and Productivity
improvement
4
Why Lean Office?
“In America today we have good people
working in poor processes. What we want
is good people working in great processes”
Michael Hammer
5
Why Lean Office?
“ Toyota Production System will not work unless it
is used as an overall management system. TPS
is not something that can only be used on the
Production floor.”
Taiichi Ohno

Value Added vs. Non-Value Added Activities
» Value Added (VA)
– The customer is willing to pay for it
– Physically transforms the product (or
document or information)
– Is done right the first time
» Non-value Added (NVA)
– Consumes resources, but does not add value
to the product or service
» Necessary Non-value Added (N-NVA)
– Does not add value to the product or service
but are
– CURRENTLY NECESSARY
–
–
–
–
Customer Contract or specification
QS 9000 or customer standard
Government regulation
Current state-of-the-art work method or
technology

Why Lean Office?
» Only 30% of the total
costs are directly
manufacturing
» Where is the rest of
the money being
spent?

Lean Organization
Process View
Customer
Business Operations
Delight
A streamlined flow of goods or services through an organization in concert
with customer demand and requirements
We can begin to reduce the complexity
of an organization by implementing
Lean Tools and Techniques in support
processes. We can gain a competitive
advantage by streamlining the
organization, focusing on these four
areas
Streamline,
Synchronize, and
Integrate
1) Identify, manage or break the constraints
2) Eliminate waste and non value added work
3) Synchronize all activities toward customer
delight
4) Apply an employee based cross functional
continuous improvement plan

»
Making multiple schedules due to system incompatibilities
E-mails/memos to everyone
Printing extra documents just-in-case
More information than the process requires
More information than the customer needs
Creating reports no one reads
16
Waste of Waiting

Time lost when people and resources are waiting:
Unbalanced workload
Equipment break downs
Batch processing
Waiting for information
Waiting for copiers/faxes
Waiting for customer response
Waiting for an internal response
17
Waiting Waste

3. Detail the Steps
Process Mapping Guidelines
• Gather the information from the actual process - “go
see” where the work is being performed
• Get the real data versus the theoretical way it should
be done or the way people “think” it is done
• Use the “experts” (people doing the work) to develop
the maps
• Use the maps as a microscope on the process to allow
you to see where to make improvements

Starbursts)
NOTE: Paste a bright green post-it near improvement
opportunities that you have identified from you current state
value stream map. Write a small description of the waste
and how to fix it.
STARBURST
5. Analyze the Process Map
2. Identify opportunities to combine steps that occur between two or
more people
•
In order to eliminate handoffs or delays
3. Identify opportunities to perform work simultaneously instead of
sequentially
•
In “parallel” instead of “serially”. What is the earliest a
particular work step can occur?
•
Identify opportunities where work (documents or information)
can be delivered to the next person or operation one piece at
a time instead of delivering work in a “Batch”
•
Identify opportunities to build into the process signals or
advanced notice to downstream departments to prepare to
receive or produce work
56
Parallel vs. Serial Processing
57
5. Analyze the Process Map
4. Identify opportunities to “co-locate” people doing work:
•
To improve communication
•
To reduce the effects of handoffs and of transportation
distances.
5. Identify opportunities to automate any of the work
•
Electronically capture and transmit documents (scan-mail)
–
•
Electronically capture and report process events and work
status
–
•
Replace manual handoff with an electronic handoff
Replace hard copy forms, worksheets, or spreadsheets with
electronic versions, accessible from the network
Electronically combine several documents into a single
database
58
5. Analyze the Process Map
6. Identify problems which if solved will reduce time or error rate
7. Determine whether the entire process is a candidate for
“reengineering”
59
6.
Develop Future Map
Now that opportunities for improvement have
been identified through the analysis step, start a
new map incorporating the improvements you
identified. Remember to take a picture of your
before and after states.

7. Develop & Implement Action Plan
»
Create a list of actions
»
Prioritize the list – Impact-Difficulty Grid
»
Assign responsibility
»
Define due dates

Sustaining Improvements
» Recognize that several follow-up activities may be necessary:
– Implementing and refining a measurement or performance monitoring
system
– Initiating additional improvements or corrections based on the
measured results of the improved process
» Reconvene Team representatives until the projected levels of
improvement have been achieved and sustained for at least
three months

5S & Visual Management
• A proven method used to systematically
organize, clean, and standardize the
workplace
If you can’t do 5S,
you can’t do Lean!

Elements of a 5S Program
•
•
•
•
•
Sort - what is not needed, sort through, then sort out; “When in
doubt, throw it out!”
Set-in-order - what must be kept; make visible and self-explanatory
so everyone knows where everything goes
Shine - everything that remains. Clean equipment, tools and
workplace
Standardize - implement best practices to keep the workplace
clean and organize
Sustain - making a habit of properly maintaining correct procedures
70
What is Standardized Work?
•
Standardized Work is a method enabling employees to improve their
control of operations and measure their performance against
documented standards
•
Performance is optimized by reducing variation and waste in
operations by the efficient arrangement of people, products, and
machines, thus improving product quality
71
Cellular / Flow Processing
•
•
Arrange people and workspace to achieve one-piece flow
Minimizes wastes of:
• Defects
• Transportation
• Overproduction
• Inventory
• Waiting
• Motion
• Non-utilized Talent
• Extra Processing

Single piece flow

Pull process control

Reduced waste

Improved floor space
72
One Piece Flow
Consider these conditions for “flow” in the office
setting:
1. One piece processing versus “batch”
2. People in process sequence
3. Multi-process work
sequence
4. Multi-process skilled
people
5. Synchronization of
operations (work balance)
73
Poka-Yoke / Mistake-Proofing
Poka-Yoke is the
removal of all
potential causes of
error either
through design,
process, or
mistake-proofing
devices, to ensure
consistent process
results
Poka-Yoke helps build quality into processes to
achieve “Zero Defects”
74
Kaizen
• Kai = Change
• Zen = Good (for the better)
• Kaizen = Continuous Improvement
Kaizen has a bias for action!

Create a sense of urgency
Have a vision, communicate it continuously
Focus on key process drivers
Remove all obstacles to achieve the vision
Create short term victories
Don’t declare victory too soon
Speak with data
–

Don’t assume
Analyze data – doubt it
Make decisions with data
Take action based on data
Check results
82
The ideal first project…
» … is clearly and unambiguously
measurable. This is not always
possible for administrative Kaizens.
» …satisfies a widely-perceived need.
» … is a repeatable process.
» … is self-contained, not subject to
uncontrollable external influence.
83
Administrative Process Improvement
» Administrative Kaizens are often discontinuous miniKaizens.
» The team meets first to understand the nature of the
project and decide what they will need to know. The
current state is described. A process map may be
developed.
» Any information unavailable at the first meeting is
provided prior to the second meeting.
» The second meeting is generally one day. The project
is analyzed and a complete action plan is developed.
The plan is implemented and the outcomes are
monitored.
» If necessary, a follow up meeting is held.
84
The Kaizen Project Team
» Team members are selected on a project-byproject basis.
» There is a team leader chosen to facilitate and
coordinate. The leader is not in charge in the
traditional sense.
» The team can be comprised of:
 Subject matter experts in the target area.
 Others in the same segment of the organization.
 Individuals from other areas of the organization.
This includes technical staff.
 Individuals from outside the organization.
85
The Kaizen Project Team
An open, egalitarian structure is
important.
When Kaizen project work is
underway, organizational position is
irrelevant and disregarded.
All team members are considered
equal within the team.
86
Key Kaizen Tenets
» An open atmosphere is critical. Free
thinking and contribution are
necessary.
» Everything is open to question. No
assumptions are made.
» A Kaizen event is not developing a
list of ideas or recommendations to
be studied. The outcome is
implemented.
