“Why is important to know which part has the greatest impact if changed? For two reasons. First, if you experience disturbance in a system, you can now know on which level to seek the error that needs to be fixed. Second, if you wish to change a malfunctioning system, now you know what impact your interference will have on different levels. For example, if you have a company which experiences a deficit for years, you know that just changing the employees won’t make a big difference unless they will also have a better work ethic (change on the interconnection level). You can also change the function of your company —you can downsize the company to one worker, yourself. Thus, you can save on employee wages, taxes, etc. However, this way your affair hardly can be called company, rather an individual business.”
