Hi Sammy. I agree with you: evaluating investments before making them is very important. The foundations of this procedure date back to the late 19th and early 20th centuries, with economic engineering. Fundamental contributions came from modern corporate finance (Irving Fisher) and the development of management accounting in the 20th century, paralleling the spread of management control in industrial companies. Getting an investment assessment wrong, in some cases, can even compromise a company's future.
