In order to simplify and standardize continuous improvement, different methods such as 5W or Ishikawa are used.
Standardization means that the problem-solution methods are systematically processed. Then the results of different users can be more objectively compared and the target improvements become easier and more objective to evaluate.
An important advantage of standardized problem-solving methods is that they are self-explanatory. They can be used without extensive training, because each user is guided step by step through the problem solving process.
As each user applies the methods in the same way, additionally the evaluation documentation becomes standardized.
