Think of the facade as you would a financial broker that manages your investments. You provide your broker investment capital and that broker works behind the scenes to invest your money in different bonds and stocks that meet your desired level of risk. To do so, the broker must understand what companies suit your risk profile and are a sound investment; where to find those companies; how to purchase stock in your name; what’s been going on in the market—navigating the complex financial landscape on your behalf. Your interface to this broker is the simple exchange of money, along with some high-level specifications for your investment strategy.
