Business activity is continuously connected with foreseeing the future. It is exactly the future, and not the present conditions that decides about success of any enterprise. Whether the enterprise will turn out to be profitable and succeed on the market will result from its ability to foresee prevailing conditions on a widely understood market in the following years. What growth rate will be like, whether the branch of our interest will have to face aggressive competition, how consumer tastes and attitudes will change, in what legal environment we will have to function? Such questions can be multiplied endlessly. What therefore can we do to improve the quality of formulated economic forecasts, and, at the same time, to increase chances of achieving goals established before we start a business venture?
