General systems theory is often used to solve many problems.
Problems are nothing new for human being. Since the creation of mankind, it is a common fact that human beings are continuously facing different problems and adopt various techniques to cope with these problems. Situations that may arise time to time always require some action to cope with them. Moreover, problems may be well defined and at small scale like opening a can, solving some mathematical problem and scoring in any specific game. On the other hand problems and issues may be of large scale. This may include the opening of a business which requires proper strategies, planning at each and every step. So, each and every problem always requires some specific strategy and solution. However, it does not mean that one solution is used to resolve any particular issue only and it is not suitable for some other problem.
2. After that you have to choose the strategy in order to solve the problem. For that purpose you should consider all those strategies and solutions that are available. Just adopt one that you think best out of all.
Here, I want to mention that the basic reason to explain all the above mentioned details is to make it clear that problem solving always requires some specific phases whether short term goals are required to achieve or long term goals. So, here we can also say that problem solving of large scale systems can be applied to smaller scale systems as well because the basic thing to follow is to consider all the required phases accordingly.
Now, I am going to explain briefly some of the systems methodologies that are described to resolve the problems of large scale systems. I will further explain that how these strategies can be applied to smaller scale systems.
Basically, systems science and systems theory evolved to handle the real world and to resolve complex, intertwined, large scale and small scale systems problems. Remember, problems always contain some sort
