Selection of Problem Solving Method

How to Select the Right Problem Solving Method?

→ As we all know that there are many Problem-Solving Methodologies are available in daily uses.
→ But sometimes, we have a little bit confused about the selection of the right problem-solving methodologies.
→ You can use any of the below methodologies as per your requirement for problem-solving.
→ For better understanding, you can refer below the diagram for the selection of the right method.
→ First of all, we need to have an identified problem. Then we can process further.

➨ Question_01:
→ Now we need to check that the problem is a part of a well-managed process or not?
→ If it is not a part of a well-managed process then we need to implement any Quality Management System like ISO 9001 or IATF 16949, etc.
→ For your better understanding, you can refer to this article for detailed knowledge of ISO 9001:2015 and IATF 16949:2016 Explained with Examples
→ The second possibility is the problem is a part of a well-managed process.

➨ Question_02:
→ Now again we have to ask the question is the solution known?
→ Is the solution is known? then we can directly go on implement the solution just do it or it can be done by kaizen methodology.
→ For better understanding about various types and categories of Kaizen methodology refer to this article for Case Study of Kaizen Methodology
→ The other possibility is the solution is not known.


➨ Question_03:
→ Now we need to ask are any special causes available?
→ If the answer is yes, we can use the 7QC tool method. It was initiated in 1979 & it is very helpful in identify the special cause related problems.
→ Refer to this article for a Complete understanding of 7 QC Tools explained with Case Study with suitable examples.
→ If the answer is - the special cause is not available then again we need to ask a question.

➨ Question_04:
→ Now we need to check if it requires a new product or process?
→ If a new product/process is required then we can easily go for DFSS.
→ Design for six sigma (DFSS/DMADV) that is one of the popular methodologies of six sigma identified in 1995.
→ If it does not require a new product or process. Then again we need to check one more thing that is mentioned below.

➨ Question_05:
→ Is the problem is related to cycle time reduction? 
→ If the answer is no then we can directly go for DMAIC method for six sigma.
→ If the answer is yes, we have another question that is mentioned below.


➨ Question_06:
→ The last but not least question is bottleneck defect driven?
→ If the answer is yes then also we can continue to use DMAIC Method.
→ If the answer is no we should use Lean Methodology.

  1. Thank you. A valuable overview. For question 5, in the diagram, the answer for both questions are "No". Is it correct to say, it should be "Yes" for the arrow going to Question 6.
