Background
Problem solving
deeply influenced by
the methodology
developed by Walter
Shewart at Bell
Laboratories in the
1930’s
Later adopted & made
popular by
W. Edwards Deming
Methodology based
on Plan-Do-Check-
Act (PDCA) – The
Deming Cycle
Key texts: John Shook (2008) “Managing to Learn”
Durward Sobek II & Art Smalley (2008): “Understanding A3 Thinking”

The A3 Thinking Steps
What is the problem?
Who owns the problem?
What is the root cause of the problem?
What are some possible countermeasures?
How will you choose which countermeasure to propose?
How will you get agreement among everyone
concerned?
What is your implementation plan? What timetable?
How will you know if your countermeasure works?
What follow-up issues can you anticipate?
How will ensure learning and continuous improvement?
9. www.leanuk.orgLean Enterprise Academy9
Lean Managers do Two
Things
Get each person to take
initiative to solve problems and
improve his or her job
Ensure that each persons’ job
is aligned to provide value for
the customer and prosperity for
the company

Do you want to manage…..
With a process or structure that
makes it easier to:
Gain agreement (alignment?)
Clarify responsibilities (ownership?)
Mentor people on the job (ask questions

Problem Solving
In order to learn by doing we will
practice on real problems
Let me tell you about a production
problem that a certain Supervisor
had to solve
14. Solving Problems

Smith’s Problem Handout
Brown, the drill press operator in Department A was working
at his job, drilling the #1 hole in angle plates.
He had cut his finger while moving tote pans of material to the
work area.
The standard specifications for the job called for gauging one
piece in twenty for size. Brown did this and although the pain
from his finger was diverting his attention all that he gauged
seemed to be good.
He therefore had no indication that the drill was dull nor that
the machine wasn’t running at the correct speed. It was just
as the set-up man had left it. By mid-morning he had
completed five tote pans for a total of 100 pieces.
Smith the Supervisor suddenly called Brown to his desk and
reprimanded him for carelessness in his work.
Brown was angry and felt discouraged. He told the supervisor
he was going home at noon.
Smith the Supervisor was worried because Department B
needed the work now or they would stop production. The
Inspector had told him that a great many of the angle plates
were off specifications
16. www.leanuk.orgLean Enterprise Academy16
What is a Problem?
A “problem” is… the gap between the way things are
now & the way they’re supposed to be, or you want
them to be, in the future
A manager has a problem when the work assigned fails
to produce the expected results
(Ref: TWI Training Materials)

Lean…
Lean is “process-focused”.
Which process is most important?
The process where the work is being done because that’s
where things are happening or not happening that are
contributing to the GAP in performance.
What is the process of A3 Problem Solving?
The process of Grasping the Actual Situation first-hand to
link problems in performance to the process problems that
are contributing to them & looking for the causes of those
problems in the work process.

“Data is of course important,

And where do you find the FACTS of a situation?
At the Gemba – the place where the problem is
actually happening. Not in a conference room or
at a desk.

The Three Most Common
Problems in Problem Solving
1. Assuming you know what the problem is
without seeing what is actually happening
2. Assuming you know how to solve a
problem without finding out what is
causing it
3. Assuming the action you have taken to
solve a problem is working without
checking to see if it is actually doing what
you expected
In other words - Not Grasping the Situation

I. Background
New domestic plant expansion has massive
technical requirements that must be translated
from Japanese to English. The size and
complexity of the project are creating errors and
delays
A3#1 Create Robust Process for Translating Documents
II. Current Conditions
Cost overruns, delays, and errors due to:
• Sheer volume of documents
• Multiple and varied vendors (pricing, quality,
ease)
• Involvement of various departments and working
styles
III. Goals/Targets
• Simplify and standardise the process
• Reduce costs by 10%
IV. Analysis
• Challenge of translating from Japanese to
English
• Multiple varied vendors create a complex,
nonstandard process
• Overall improvement can be defined by
reduction in cost overruns
VI. Plan
Evaluate current vendor
Identify new vendor candidates
Develop bid package, distribute, and choose
winning bid
VII. Followup
Monitor cost to proposal
Review performance at end of one-year contract
V. Proposed Countermeasures
Simplify and improve process performance by
choosing one vendor based on competitive bid

Problem
Why don’t the employees
have the translated
documents when they
need them?
The documents don’t get
into the system on time
Why don’t the documents

What is the problem or issue?
Who owns the problem?
What is the root cause of the problem?
What are some possible countermeasures?
How will you decide which countermeasures to propose?
How will you get agreement from everyone concerned?
What is your implementation plan
Who, What, When, Where, How?

What follow-up issues can you anticipate? What
problems may occur during implementation?
How will you capture and feed back the learning?
42. Root Cause Analysis

Follow-up Actions
Background
Goal
Is there a clear theme for the report that
reflects the contents?
Is the topic relevant to the organisation’s
objectives?
Is there any other reason for working on this
topic (e.g. learning purposes)?
Theme: Review Questions For Problem Solving A3s
Ref: Sobek & Smalley 2008 pp 50
Current Situation
Is the current condition clear & logically
depicted in a visual manner?
How could the current condition be made
more clear for the audience?
Is the current condition depiction framing a
problem or situation to be resolved?
Are the facts of the situation clear, or are
there just observations & opinions?
Is there a clear goal or target?
What, specifically, is to be accomplished?
How will this goal be measured or evaluated?
What will improve, by how much, and when?
Are there clear countermeasure steps
identified?
Do the countermeasures link to the root
cause of the problem?
Are the countermeasures focussed on the
right area?
Who is responsible for doing what, by
when (is 5W1H clear)?
Will these action items prevent recurrence
of the problem?
Is the implementation order clear and
reasonable?
How will the effects of the
countermeasures be verified?
How will you measure the effectiveness of
the countermeasures?
Does the check item align with the
previous goal statement?
Has actual performance moved in line with
the goal statement?
If performance has not improved, then
why? What was missed?
What is necessary to prevent recurrence of
the problem?
What remains to be accomplished?
What other parts of the organisation need
to be informed of this result?
How will this be standardised and
communicated?
Is the analysis comprehensive at a broad
level?
Is the analysis detailed enough and did it
probe deeply enough on the right issues?
Is there evidence of proper 5 whys thinking
about true cause?
Has cause and effect been demonstrated or
linked in some manner?
Are all the relevant factors considered
(human, machine, material, method,
environment, measurement, and so on?

44. Acme Stamping Steering Bracket Value Stream Improvement
Background
Acme supplies stamped steel steering brackets (LH & RH) to State
Street Assembly. The product goes through 5 manufacturing processes &
shipping.
The customer uses 18,400 pcs/month & requires daily shipments in
pallets of 10 trays of 20 brackets. A pallet is either all RH or LH.
Current Situation
Lead time for steering bracket from coil steel to shipment = 23.6 days.
Of 23.6 days, only 188 seconds are spent making a bracket.
Large inventories of material between each process.
Long changeover times, downtime in welding.

Analysis
Each process operates as isolated islands, disconnected from the
customer.
Push system, material builds up between each process.
Each process builds according to its own operating constraints
(changeover, downtime etc.)
Plans based on 90 & 30 day forecasts from customer. Weekly schedule
for each department. System is frequently overridden to make delivery.
Goals
Improve profitability of steering bracket value stream.
Reduce lead time - 23.6 days to 4.5 days.
Reduce inventories:
Stamping 7.6 days to 1 day.
Welding 6.5 days to 0 days.
Shipping 4.5 days to 2 days.
Recommendations
Create continuous flow through weld & assembly
Establish TAKT time . Base the pace of work through weld & assembly
on customer demand.
Set new weld - assembly cell as pacemaker for entire value stream.
Establish EPE_ build schedule for stamping based on actual use of
pacemaker cell & pull steel coils from supplier based on actual usage by
stamping.
Improve uptime in weld.
Establish material handling routes for frequent withdrawal & delivery.
Establish new production instruction system with Levelling Box.
Follow Up
Reviews & involvement of related departments TBD.

AGREE ON
THE PROBLEM,
A HYPOTHESIS,
AND THE PROCESS
TO TRY
DECIDE WHAT ADJUSTMENTS
NEED TO BE MADE, WHAT TO
STANDARDIZE OF THE PROCESS
THAT WORKS, AND
WHAT TO DO NEXT
STUDY BOTH THE
RESULTS AND THE PROCESS.
REFLECT ON WHAT WAS LEARNED
-ABOUT CAUSE AND EFFECT.
- ABOUT OUR CAPABILITY
IMPLEMENT AS PLANNED,
ADJUST AS NECESSARY.

What Makes an A3 a Good
One?
It tells a story
It contains objective facts, data
It “resolves” a problem
But being technically “right” is only half
the battle…
Engages and aligns the organization
What really makes an A3 a “good one”
isn’t the specific collection of facts and
data that tell a perfect problem-solve. A
good A3 is a reflection of the dialogue
that created it.
