ABSTRACT
Look at the nearest synthetic product around you. Who built it and why? What needs does it satisfy? Why was a particular material chosen? Why is the shape of the product the way it is? What could be done to improve the product? As you ask yourself these questions repeatedly you will realize that at least two (decision-making) entities were involved at some point in time that caused the product to exist: the manufacturer who made the product and the end user who purchased the product (which could be you). The end user had a desire for the functionalities of the product and believed that the resources required to acquire the product were justified. In most cases the resource required is money. The manufacturer fulfilled this need by providing the product at a reasonable price and made some profit in the process.
