Why we need a "Problem Solved"? 

Problem solving is a "thinking" used in engineering when products or processes fail, so corrective action can be taken to prevent further failures. It can also be applied to a product or process prior to an actual fail event, i.e., when a potential problem can be predicted and analyzed, and mitigation applied so the problem never actually occurs.

Deaming Cycle 

The Deming Cycle, or PDCA Cycle (also known as PDSA Cycle), is a continuous quality improvement model consisting out of a logical sequence of four repetitive steps for continuous improvement and learning: Plan, Do, Check and Act. The Deming (PDCA) cycle is a procedure for improvement. It is a logical and rational guide to act in a variety of situations. One of them is to solve problems.




  • Define the problem
  • Describe the current process
  • Find and analyze possible causes
  • Develop solution(s)


  • Implement the solution


  • Evaluate the solution


  • Control plan and monitoring
