Why is it that it is important for companies to utilize both of the different branches in a company? Why wouldn't one person be able to be in both managerial and financial accounting? I personally think that if I ran a company I wouldn't want a lot of people working my finances, I would want one person that I could trust to handle everything. It may be due to the fact that I like to be in control and get things done, but when it comes to a companies finances it is not something to mess around with.
