WHAT IS “PROBLEM ” ?
“PROBLEM” means…….• Your part is not as per specification ?• Your process is not in your control?• Your internal rejection % is very high?• Your delivery performance is less than
100 %?• Your external rejection % is very high?• Your waste % is very high?
etc……….
You want to solve problem…..
• Temporarily…..or
• Permanently……• And become problem
solver
Have got Problem ?Do what you can, where you are and
with what you have got.

Knowledge
So what to do…..?
There are ways and techniques for solvingeach and every problem but the urge forsolving, make these techniques powerful.
Because………..
Even to the hardest problems... Just Urge to solve it…
So how to do it……? Solve the problems such that…

So let us know types of problem solvingtechniques………
? ? ? ?1 2 3 4 …..
1. Define the problem
2. Build a Team
3. Containment action
4. Determine the root cause
5. Verify the root cause
6. Corrective Action
7. Preventive
8. Congratulate the Team
And Many others……P
Why use this approach…..?
• This technique has proven itsusefulness in other companies
• Common methodology –everybody understands how
• Focus on Fixing it - first time right• Define priorities• Sharing the lessons learned with
others
When do we use this technique……….?• 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• ...
Major impact or Repetitive issues
This technique is based on……….

How does the technique in moredetail look like……….?
1… Clarify the problem2… Break down the problem3… Target Setting4… Determine Root Cause5… Develop Countermeasures6… See Countermeasures through7… Confirm Results & Process8… Standardize process - Sustain the gain
How to fit PDCA with this technique…?
Problem Solving Guide…
Let us take Step : 1- Clarify the Problem
• What do you understand by the problem ?• What is exactly the problem is ?• How you define the problem ?• Is problem the gap between desired and
actual ?• What is and how is affected by the
problem – How you say it is a problem ?
Problem Solving Guide…
Step :1 Clarify the Problem
Desired / IdealSituation
Actual / CurrentSituation
Gap = ProblemGap = Problem
• What we understood is problem means “GAP”
between desired and actual situation.
• Now also identify who is getting affected by
Problem, what is the cost, what is priority etc….
Step :1 Clarify the Problem

Step :1 Clarify the ProblemLet us take type of problems in easy wayType 1 : Standard not achieved
The Standard = 100 % on time delivery
Actual = 82 % on time delivery
15.50 mm
Requirement is 15.75 ± 0.1mm
( 15.65 to 15.85 mm)
Step :1 Clarify the Problem
Type 2 : Standard is achieved but a higherstandard is required now
Actual 100 % on time delivery @ 2week lead time
New standard 100 % on time delivery @1 week lead time
Now new higher standard is target….
Step :1 Clarify the Problem
Type 3 : Consistency in the achievingresult is not there
Time
The standard
Actual
Step :1 Clarify the Problem
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 definedproblems: by region, location, department,product, channel, customers, etc.
• Specify the point of cause: the problem is presentin a specific part of the process
Step 2: Break down the problem Step 2: Break down the problem
Step 3: Target setting Step 3: Target setting
What are GOOD and BAD targets …….?
• When you set the target you should bevery specific about the requirement ordesired result of the actions you are goingto take.
• What• When• Where• How much
Step 3: Target setting Step 4: Determine root cause

Step 4: Determine root cause
Followings are the ways of finding root cause…….
• A team is require to do this activity• Please note that any thing come in
mind as a cause you should write• DO not criticize anybody for silly
thought• Do not get trapped by your own train of
thinking• Note down all the thoughts came from
team’s mind
Step 4: Determine root causeBrainstorming
Step 4: Determine root cause
Pareto’s principle says you should attackfirst on the cause which are affecting 80%

• Try to make your effect measurable– Can you plot graph for the effect ?– Can you calculate the figures for effect ?
• Sometimes ‘6M’s’ can be replaced withrequired headers like :
– Policies– People– Procedures– Plant (Facility)– Programs (Software)
