Financial Modelling: An imperative sound for decision making

What is Financial Modelling?
Financial modeling is the task of building an abstract representation of a financial decision making situation. This is a mathematical model, such as a computer simulation, designed to represent the performance of a financial asset or a portfolio, of a business, a project, or any other form of financial investment.
Theoretically speaking, a financial model is a set of assumptions about future business conditions that drive projections of a company’s revenue, earnings, cash flows and balance sheet accounts.
However, financial modeling is a general term that means different things to different users. In the US and particularly in business schools it means the development of a mathematical model, often using complex algorithms, and the associated computer implementation to simulate scenarios of financial events, such as asset prices, market movements, portfolio returns and the like. Or it might mean the development of optimization models for managing and controlling the risk of a financial investment. In Europe and in the accounting profession financial modelling is defined as cash flow forecasting, involving the preparation of large, detailed spreadsheets for management decision making purposes.
