It is important to really find why the problem occurs
to really identify the Root Cause
to really fix the problem
Problem Solving Methodologies
(Root Cause)
When we see a problem we tend to look under the lamp and jump into an early conclusion how to solve it
It feels good to do something about it quickly
but do it the right way
Core Principles when searching for the Root Cause
-
Concentrate on solving reoccurring root causes rather than solving just symptoms
-
Do not ignore the importance of treating symptoms for short term relief
-
There can be, and are, often more then one root cause
-
Focus on 5 Way and How rather than who is to blame (Ask Who?, What?, Where?, When?, Why? And How? Did the problem show upp)
-
Be systematic and look for evidence to back up the found root cause
-
Try to find a way to solve the rout cause to prevent it from appearing again
When performing a Root Cause analysis it is important to take a comprehensive and holistic approach and to use all the knowledge available in the total organisation (Cross functional)

There are different methods when searching for Solutions e.g.
-
5 W + H (Ask Who?, What?, Where?, When?, Why? And How? Did the problem show upp)
-
Change analysis

Fish bone analysis
A 3 method
1. Define the problem
2. Current state
3. Wanted State
4. Analyse the root causes
5. Generate and test
countermeasures
6. Implement and sustain
improvements
(implementation plan)
7. Follow up results
8. Standardization
9. Lessons learned
Trial and error
Variation and selection is a very powerful method
