Nobody denies the usefulness of analysis.
Nevertheless, managers of some large companies sometimes think that analytical services are less efficient than a clever and resourceful expert who knows what it takes. In countries where money is here today and gone tomorrow, and one s success is determined exclusively by connections, knowledge of the key figures and ownership of keys to the powder room , analysis is not imperative. But the honeymoon is soon over, and managers eventually embrace the possibility of regular data analysis. New circumstances make analysis a necessity where it seemed to be an extra burden only yesterday. At the same time, the demand for tools with transparent mathematics and understandable analytical methodology is increasing in scientific research.
