Although the steps are sequential, any one of them can be repeated. For instance, deep thought about Step 4 might lead you to realize that you in step 2 incorrectly.
And evaluation of outcomes at the final stage may be negative, calling upon you to repeat the process. In this sense, the model functions as a sort of algorithm, with feedback loops at each stage.Defining root causes of a problem is often the most difficult part of problem solving.
You know that something is wrong. You see something isn’t working. But the causes remain vague or elusive. The drill-down technique helps you resolve this issue by breaking the problem down into progressively smaller pieces.Read more on success.com
