give a short description of how problem isolation is done
Troubleshooting Troubleshooting or dépanneuring is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state.
Withering away of the state Although Engels first introduced the idea of the withering away of the state, he attributed the underlying concept to Karl Marx; other Marxist theorists—including Vladimir Lenin—would later expand on it.[1][3] According to this concept of the withering away of the state, eventually a communist society will no longer require coercion to induce individuals to behave in a way that benefits the society.[1][2] Such a society would occur after a temporary period of the dictatorship of the proletariat.[2]
