How to implement Segregation of Duties?

This is actually quite a simple process, think of it like checks and balances. 

By utilizing these steps you will not only deter fraud within your organization, but you will also be able to make sure that the people who have their hands on your money are actually managing it properly.

You will be able to catch mistakes that would slip through the crack otherwise.
