Em vez de uma estimativa pontual, compreender os factores que podem influenciar o futuro

"Competence in forecasting does not mean being able to predict the future with certainty. It means accepting the role that uncertainty plays in the world, engaging in a continuous improvement process of building your firm’s forecasting capability, and paving the way for corporate success. A good forecast leads, through either direct recommendations or informal conversation, to robust actions — actions that will be worth taking, no matter how the realities of the future unfold. In many cases, good forecasting involves recognizing, and sometimes shouting from the rooftops about, the inherent uncertainty of the estimates, and the fact that things can go very bad very quickly. Such shouts should not invoke the paranoia of Chicken Little’s falling sky; instead, they should promote the development of contingency plans to both manage risks and rapidly take advantage of unexpected opportunities."

"Simply focusing on the output of the model (the projected sales figures) rather than the input (such as unemployment and consumer confidence) can actually do more harm than good. Whirlpool’s planners use their industry forecast models to focus executive attention, not replace it. The planners present the model for the upcoming year or quarter, describing the logic that has led them to choose these particular levels of demand and the reason the outcomes are meaningful. Executives can set plans that disagree with the forecasters’ predictions, but everyone has to agree on which input variables reflect an overly optimistic or pessimistic future. Even more important, managers can begin influencing some of the driving forces: For example, they can work with retail partners to encourage remodeling-driven demand to offset a drop in housing starts."

"No model is objective, reflecting some universal truth. Instead, business models represent highly subjective views of an uncertain world. Rather than seeking the ultimate model or expert, managers should adopt the axiom cited by General Dwight D. Eisenhower regarding the successful but highly uncertain D-day invasion in World War II. He asserted that “plans are nothing; planning is everything.” A good forecast informs decisions today, but equally important, forces us to consider and plan for other possibilities."
