Arrange the stages in problem sequentially 1. defining the problem 2. evaluating information 3. takin action 4. gathering information

Explanation:

First of all you must define what the problem is. Only then will you be able to objectify what you want to do with this problem and what the following steps you must take to reach the goal. Then collect information about the problem, how to handle it, how to solve it, what must be done so that other problems are not generated from this problem, among other information.

The third step is to evaluate the information collected and determine what is relevant to that particular problem and what information is irrelevant and needs to be discarded. After that, it's time to act. At this point you should take action.
