We don't try to predict the future in order to contol it, we try to predict the future to prepare a proper response to the possible emerging events.
Those who are not engaged in estimating the possible outcomes of future events and preparing to manage in the presence of this uncertainty will be managed by those events. Whether we are preparing for them or not, they are coming
Before accepting the notion that estimating, forecasting, and preparation are not needed, ask what business can we work in where the future cost, schedule, and technical performance of our work is of no interest to those providing the money for our efforts?
