Problem Solving
Problem’s are the Golden Eggs
We can’t solve problems by using the 
same thinking we used when we 
created them…. 
“In any moment of decision the best thing 
you can do is the right thing, the next best 
thing is the wrong thing, and the worst thing 
you can do is nothing” 
Do not put a Band Aid – Solve the root of 
the problem
Barriers to 
Problem Solving 
• Failure to recognize the problem – no sure what the problem is 
• Conceiving the problem too narrowly, not sure what is happening 
• Making a hasty choice, not sure what you want 
• Failure to consider the feasibility of the solution 
• Failure to consider all consequences, not enough resources 
• Failure to know to communicate what is possible 
• Failure to define what YOU did that was responsible for your success 
• Team attitudes like complacency, ridiculing others ideas, lack of accountability, 
dysfunctions, fear of change, lack of trust and doubts
Attitudes That Kill 
Creative Ideas 
That beyond our responsibility 
Don’t be ridiculous 
It’s too radical a change 
Top management will never go for it 
That’s not our problem 
It costs too much 
That’s not our problem 
Are our competitors doing it 
It isn’t in the budget 
We don’t have time 
We’ve never done it before
Don’t Jump over the 
Problem 
Be with the 
Problem 
Assumptions Vs Observations
Don’t Jump over the Problem 
• Jumping to a solution 
orients the team to 
deploy only one thing, 
which could be 
insufficient or just 
wrong. 
• It stops the team’s 
search to find the true 
reason for the problem. 
• It reduces your effort to 
find a real solution.
Be with the Problem 
• Explore the current 
work situation 
• Go to the place of 
work where problems 
happen, to gain 
Insights into the work 
where work is Done 
• You learn, what is 
really happening… 
• It avoid False Starts!!!
Problem…. 
 Problem is the discrepancy between 
the current situation and the 
standard for that situation 
 A standard is a specific established 
“KNOWN” expectation of what should 
be for a given situation 
 The current situation is the way 
things are now 
 A discrepancy is a measurable or 
quantifiable difference between a 
standard and the current situation
FOUR-PHASE PROBLEM 
SOLVING PROCESS
About PDCA Authors 
Walter Shewhart 
Discussed the concept 
of the continuous 
improvement cycle 
(Plan Do Check Act) in 
his 1939 book, 
"Statistical Method 
From the Viewpoint of 
Quality Control 
W. Edwards Deming 
Modified and 
popularized the 
Shewart cycle (PDCA) 
to what is now 
referred to as the 
Deming Cycle (Plan, 
Do, Study, Act).
When do we use the PDCA 
• Significant or repetitive complaints 
• Repetitive human errors occurring 
during a specific process 
• Repetitive equipment failures 
associated with a specific process 
• Performance is generally below 
desired standard

Step 1: Clarify the Problem 
• We need to 
understand the 
current situation 
(Measured), Ideal 
situation (Standard). 
• Why is it a problem? 
What is the KPI 
affected? What is the 
cost? Relation to 
objective? Why is it a 
priority?
Step 1: Clarify the Problem 
What is a problem? 
• Anything that 
deviates from the 
standard or target 
• A gag between 
actual and desired 
condition 
• An unfulfilled 
customer’s need
Step 1: Clarify the Problem 
Problem type - 1 Problem type - 2 Problem type - 3 
Standard not Achieved 
Actual (100% 
on time @ 2 
weeks lead 
time 
Standard achieved, but a 
higher standard is now 
required 
The new higher standard 
is target 
Performance to 
standard varies (not 
consistently 
achieved
Step 1:Evaluate The Problem 
The criteria you use to guide this evaluation include: 
 Importance - How serious is the problem in light of cost, safety, 
or quality, etc? 
 Urgency - How soon should it be solved to avoid more serious 
problems. 
 Tendency - Is the problem getting worse, staying the same, or 
getting better? 
Problems Important Urgency Tendency

3. 
4.
Step 2 : Break down the problem
Step 2 : Break down the problem 
• Requires to study the process to detail 
• Dedicate sufficient time for the breakdown 
• Study the steps of the process, interact with people, 
get data, documents, understand tools: Learn 
• All problems can be divided into Smaller defined 
problems: by region, location, department, product, 
channel, customers etc. 
• Specify the point of cause: the problem is present in 
a specific part of the process
Step 2 : Break down the problem
Step 2 : Break down the problem 
• Specify the point of cause by studying the 
process 
• Specify the point of cause is necessary for 
effective Root cause Analysis
Step 3 : Target Setting 
Target 
Characteristics: 
 Must be quantifiable 
 Measurable 
 Achievable 
 Time Bound
Step 3 : Target Setting 
Do what: Increase 
To what: Percent of usable parts produced on presses 
4, 5 and 6 
How much: From 90% to 95%

Step 4: Determine the Root Cause 
Why Root Cause Analysis? 
• To solve problems on structural basis 
• To ensure problems do not return 
• To ensure sustainable improvements are made. 
• Identifying potential causes 
• Challenging those potential causes 
• Making reasonable assumptions about the most likely cause 
of the problem 
• Investigating to get the needed facts while continually asking 
“Why?”
Step 4: Determine the Root Cause
Step 4: Determine the Root Cause 
• Cause and Effect Diagram 
• 5 Why’s
Cause and Effect Diagram 
• it ask yourself, "What Happened?" and "Why?“ 
• "What happened?" tells you the Effect. 
"Why?" tells you the Cause.
Cause and Effect Diagram 
• Try to make your “Effect” measurable – can you 
graph it? 
• Sometimes, the ‘5M’s’ are replaced with ‘P’s’ for 
Office processes: 
Policies 
People 
Procedures 
Plant (Facility) 
Programs (Software) 
Price 
Promotion 
Processes 
Planet 
• Do not waste time discussing the branches 
Just Do it !!!! 
• You can use what fits your needs
5 Why’s
5 Why’s
5 why’s 
• Don’t need to do exactly 5 Why’s ? 
 You may find yourself using 3 to 7 “Why’s” or more on a 
problem 
 “Strive for 5” Why’s (don’t quit too early!) 
 Use as many as you NEED to get to ACTIONABLE Root 
Cause 
 Base “Why’s” on Facts and Observations, not Opinions 
• Test your “Why” logic by using “Therefore” in 
reverse. 
Make the tools work for you, don’t be a slave to the tools
Step 5 : Develop Countermeasures
Step 5 : Develop Countermeasures 
Evaluation of ideas 
1. Cost-benefit Analysis: The method is usually 
run in three steps: 
 Definition of all elements causing costs of idea 
implementation 
 Definition of all elements causing benefits of idea 
implementation 
 Comparison sum of all costs with the sum of all 
benefits
Step 5 : Develop Countermeasures 
2. Evaluation matrix 
 The main goal of evaluation matrix is to evaluate an 
 idea in accordance to several factors or criteria. 
Score = Rating x Weight
Step 5 : Develop Countermeasures 
• Good problem solving and countermeasure 
preparation will drive an organization to: 
 Productive self-criticism 
 More robust systems and processes 
 A higher-level understanding 
The countermeasure cycle is a team effort! 
Effective Problem Solving with robust countermeasures lead 
to better processes!
Step 6 : See Countermeasures through 
• Share information with others by informing, reporting and 
consulting 
• Review the progress of the action plan and the results in 
regular review meeting 
• Ensure that your countermeasures do not create adverse 
effect to other upstream or downstream processes. 
• If there’s a gap between implementation and people engaging 
with the new process, you must retrain. 
Do Not Merely Communicate By Email
Step 7 : Confirm Results & Processes 
 Evaluate if target was achieved or not 
 Evaluate the process and ensure that it is 
sustainable 
 Confirm negative and positive effects 
 Share evaluation with people involved
Step 8 : Standardize process 
• Set successful processes as new standard 
• Share the new standard.

Step 2 : Break down the problem • Requires to study the process to detail • Dedicate sufficient time for the breakdown • Study the steps of the process, interact with people, get data, documents, understand tools: Learn • All problems can be divided into Smaller defined problems: by region, location, department, product, channel, customers etc. • Specify the point of cause: the problem is present in a specific part of the process
  • 24. Step 2 : Break down the problem
  • 25. Step 2 : Break down the problem • Specify the point of cause by studying the process • Specify the point of cause is necessary for effective Root cause Analysis
  • 26.
  • 27. Step 3 : Target Setting Target Characteristics:  Must be quantifiable  Measurable  Achievable  Time Bound
  • 28. Step 3 : Target Setting Do what: Increase To what: Percent of usable parts produced on presses 4, 5 and 6 How much: From 90% to 95% By when: June 1, 2008 80 70 60 50 40 30 20 10 0 1-May 8-May 15-May 22-May 29-May 1-Jun 5-Jun Avg. percent of weekly usable parts on presses 4,5,& 6 5% std 95% Std Avg. percent of weekly usable parts on presses 4,5,& 6

  • 30. Step 4: Determine the Root Cause Why Root Cause Analysis? • To solve problems on structural basis • To ensure problems do not return • To ensure sustainable improvements are made. • Identifying potential causes • Challenging those potential causes • Making reasonable assumptions about the most likely cause of the problem • Investigating to get the needed facts while continually asking “Why?”
  • 31. Step 4: Determine the Root Cause
  • 32. Step 4: Determine the Root Cause • Cause and Effect Diagram • 5 Why’s
  • 33. Cause and Effect Diagram • it ask yourself, "What Happened?" and "Why?“ • "What happened?" tells you the Effect. "Why?" tells you the Cause.
  • 34. Cause and Effect Diagram • Try to make your “Effect” measurable – can you graph it? • Sometimes, the ‘5M’s’ are replaced with ‘P’s’ for Office processes: Policies People Procedures Plant (Facility) Programs (Software) Price Promotion Processes Planet • Do not waste time discussing the branches Just Do it !!!! • You can use what fits your needs
  • 37. 5 why’s • Don’t need to do exactly 5 Why’s ?  You may find yourself using 3 to 7 “Why’s” or more on a problem  “Strive for 5” Why’s (don’t quit too early!)  Use as many as you NEED to get to ACTIONABLE Root Cause  Base “Why’s” on Facts and Observations, not Opinions • Test your “Why” logic by using “Therefore” in reverse. Make the tools work for you, don’t be a slave to the tools

  • 39. Step 5 : Develop Countermeasures
  • 40. Step 5 : Develop Countermeasures Evaluation of ideas 1. Cost-benefit Analysis: The method is usually run in three steps:  Definition of all elements causing costs of idea implementation  Definition of all elements causing benefits of idea implementation  Comparison sum of all costs with the sum of all benefits
  • 41. Step 5 : Develop Countermeasures 2. Evaluation matrix  The main goal of evaluation matrix is to evaluate an  idea in accordance to several factors or criteria. Score = Rating x Weight
  • 42. Step 5 : Develop Countermeasures • Good problem solving and countermeasure preparation will drive an organization to:  Productive self-criticism  More robust systems and processes  A higher-level understanding The countermeasure cycle is a team effort! Effective Problem Solving with robust countermeasures lead to better processes!
  • 43.
  • 44. Step 6 : See Countermeasures through • Share information with others by informing, reporting and consulting • Review the progress of the action plan and the results in regular review meeting • Ensure that your countermeasures do not create adverse effect to other upstream or downstream processes. • If there’s a gap between implementation and people engaging with the new process, you must retrain. Do Not Merely Communicate By Email
  • 45.
  • 46. Step 7 : Confirm Results & Processes  Evaluate if target was achieved or not  Evaluate the process and ensure that it is sustainable  Confirm negative and positive effects  Share evaluation with people involved
  • 47.
  • 48. Step 8 : Standardize process • Set successful processes as new standard • Share the new standard.
