Modeling  A tool to manage complexityLet's forget systems for some time. Let's talk about puzzles.
What are the ways that you will adopt so that you can increase the chance of coming out with the right solution?
Let me explain. As I have already specified that the puzzle is complex, the prerequisite to solve the puzzle correctly is to understand the puzzle in the right way. If you try to directly solve the puzzle without understanding, it is very unlikely that you will come across the right solution.
Therefore Understanding/Analysis is a prerequisite to solve any complex problem/puzzle.
Now think about the different techniques that you will use to analyze or understand a complex puzzle? Let's say you have a paper and a pencil with you. Now what would you do so that you have a better understanding of the puzzle? Some of you will take down the keywords, some of you will use some graphics like circle, triangle, rectangle etc. Some of you will draw real world graphical drawings, some of you may use some graphs like pie chart, bar chart etc. What exactly are you trying to do while you were drawing these graphical or textual artifacts?
"Whenever a human brain encounters something which is difficult to understand or something which is difficult to comprehend, implicitly or explicitly the human brain tries to model the problem."
What do we understand by "Modeling"?
"Modeling is a technique wherein one uses solid or graphical representations to represent fluid/unclear aspects of the problem or the system so that it could be understood in a much better way".
